\chapter{INTRODUCTION}
 
Hi \TeX\  fans, the time has come to document the new
version of the macro package, PHYZZX.
Vadim Kaplunovsky has updated it to
run under \TeX 1.
Since we envision this to be the penultimate version
of PHYZZX, except for minor corrections to remove heretofore
undiscovered bugs, it now pays to explain what PHYZZX is
and how to use its various features in some detail.
For those of you who are familiar with the old version of
PHYZZX you can rest easy, this version has been designed to be
as upward compatible as possible.
Unfortunately, there are a few minor changes in the way some
macros work simply because Knuth changed \TeX\  and made it
impossible for us to keep some of the old commands.
In general the changes make things easier to use and any file
written for \TeX 97 will, with very few changes, run on \TeX  1.
For this reason the adventurous user can begin by ignoring this
writeup completely and try to run his old files.
If luck is with you, you will not have to change anything;
if luck deserts you, then either PHYZZX will help you along
(only somewhat likely) or you will have to do a little reading.
 
Our present incarnation of PHYZZX resides in two places.
The FMT file (a term designed to strike terror into the hearts of
those who have not been initiated into the high mysteries)
is on the T--disk, and this is the version you really want to use.
One uses the FMT file because it loads much faster and so you don't
have the interminable wait for something to happen while the computer
is reading all of the definitions contained in PHYZZX TEX.
To use the FMT file all you have to do is make the first command
to \TeX\  say {\tt\&phyzzx} instead of putting
\tc{\\input phyzzx} in the file.
 
For the curious we try to keep an updated version of the
file PHYZZX TEX on the theory group disk.
People interested in mucking around in the guts of this file
in order to see how things were done and what goodies, not described
in this writeup (and there are many),  are available
can access this disk by
saying
\tc{GIME PUB\$TH }
If you wish to use this file to convince yourself how much better it
is to use an FMT file, you can do this by accessing the PUB\$TH disk
and starting your file with
\tc{\\input phyzzx}
{\it For cognoscenti\/}:
as in earlier incarnations you can tailor much of PHYZZX to
your liking by having a file MYPHYX TEX on your A disk.
Each time you run PHYZZX it loads this file.
Any definitions which are in this file then take precedence over
those specified in PHYZZX.
So much for generalities, now on to specifics.
 
\chapter{BASICS}
 
\section{What is \TeX\ ?}
 
In order to make this as simple as possible for the first time
user, we will say a few words about what \TeX\ is, before going on
to talk about what PHYZZX does.
 
\TeX\ is the baby of Donald~E.~Knuth of Stanford University and
it is our choice for the best available text processor for
use at SLAC.
{\it Clear as mud!} you say. {\it What the hell is a
text processor ?}, you say.
{\it How is it different from Xedit and Wylbur ?}, you say.
Tell you what I'm gonna do, I'm going to tell you the answers to
these questions even if you weren't perceptive enough to ask.
A text processor is to Xedit and Wylbur what a publishing company
(as embodied by editors and printers) is to
a technical typist; namely, it is a thingamajig which takes a
crudely typed manuscript and turns it into a book.
Physicists and engineers all know that the
nicer your paper looks before it goes out, the more your
colleagues believe what is in it.
Therefore we all want to use \TeX\
to prepare our papers for journals, summer schools
and conference proceedings.
Some of us (hopefully that means some of you reading this
introduction) will use \TeX\ to type our own papers, and some
of us will rely on others for this task.
In any event somewhere in that chain someone has to know how to
use the thingamajig or beautiful manuscripts just won't come out the
other end.
In that case our colleagues won't know all of the wonderful things
we have to say.
To facilitate this process to some degree we wrote the macro package
PHYZZX. In order
to make PHYZZX and \TeX\ more accessible to people at the
lab, we have generated this writeup.
 
As I said,
to all intents and purposes you and Xedit (or you and Wylbur, if
you insist on living in prehistoric times) make a typist.
Actually, you make a pretty good typist for text, but you
don't do too well as a technical typist because neither
Xedit nor Wylbur does a very good job at typing equations.
You plus Xedit plus \TeX\ make a stupendous technical typist
and a remarkably good printing company.
Pursuing this analogy the process for producing a beautiful
book quality manuscript starts with somebody typing the
first draft.
This somebody is presumably you, the reader, and the
tools you use are your trusty computer terminal and an editor like
Xedit.
Obviously I have no intention of explaining how to use Xedit
since this is probably unnecessary and anyhow, everything you
have to know for the purpose of typing a text file
can be easily learned by reading the {\bf IBM Virtual Machine/
System product: CMS Primer}.
Hence, this writeup assumes that you know how to log on to the
computer and use the editor.
 
To use the editor to start collecting a file which \TeX\ will
turn into a beautiful paper, memo, or letter, you have to
follow a simple procedure.
First, in your incarnation as typist, you have log on
and enter an editor (e.g., Xedit) by telling it you want to
create a file whose name is {\bf CRAP} and whose filetype is {\bf TEX}.
You accomplish this feat by typing something difficult like
\tc{X {\rm (or XEDIT)} CRAP TEX A }
whereupon the powers that be will throw you into the editor.
At this point, since you are a person of discerning tastes,
the very next line you enter is
\tc{\\input phyzzx}.
This command will make sure that when you tell the computer
to print a version of the paper it will become an editor and instruct
the typesetter to lay out the copy according to the criteria
established by the macro package PHYZZX.
The very next thing you do is skip a line (i.e., enter a blank line)
in order to make your copy easy to read, and then
start to enter your copy.
So much for you as a typist.
 
\subsection{You As An Editor: Correcting a Mistaken Impression}
 
The preceding discussion indicates that you are to take your
manuscript and type it into the editor in exactly the same way
as you would at a typewriter.
While this is a possible way of proceeding it is not really
the best way to do things.
In order to you to understand why this is true, you have to
understand that once you have functioned as a typist, the
next thing you have to be is an editor.
 
An editor's job is to make sure the text looks good and that
the printer knows how he is supposed to layout the copy which
he receives.
For example, he has to know:
how much space to put between lines of text,
what font to set chapter headings in, how much space to skip
before and after a chapter heading, which math symbols are
exponents, greek letters etc.
Since you are the editor and \TeX\ is going to be the printer,
you have to mark up the copy so that \TeX\ and/or PHYZZX knows
what to do with it.
This feat is accomplished by including editor's comments (or marks)
in the text.
These comments (or commands to \TeX ) have to have a special
character in front of them so that \TeX\ will recognize them
for what they are; this character is the $\backslash$, and the
combination of a \\ followed by a string of characters
is called a control sequence.
One example of a control sequence is {\bf \\par} which tells
\TeX\ to begin a new paragraph.
Note that this is not a trivial thing since \TeX\ has to know
to skip some extra space between the text in different paragraphs,
indent the first line by some amount, etc.
The basic version of \TeX\ has lots of control sequences
which tell \TeX\ to do lots of wonderful things.
To learn about these things (probably more than you initially
want to know about how \TeX\ operates) you have to read
{\it selectively} in the \TeX book written by Knuth.
Since this discussion is between friends, let me warn you
this book stinks as a reference manual and ain't so hot
as an introduction to \TeX .
Knuth has a philosophy of learning by ever increasing levels of
mistakes which I (and many of my acquaintances) find
at best distracting and at worst impenetrable.
Unfortunately, this book is all that is
available as an in depth introduction
to the basic version of \TeX .
If you want to know how to do sophisticated things which lie
outside of the purview of PHYZZX you will have to read quite a
lot of it.\foot{To get a feeling for \TeX\
it is advisable to browse through the first three
chapters and read about boxes and modes.
If you just wish to type papers in the most straightforward way
you can defer this reading until you are more experienced so long as
you use PHYZZX.
However, in any event, you must
read the sections on typing math formulas,
typing displayed equations and a little bit about making boxes
since I have neither the time nor inclination to go into those things
in this writeup, and you must have a basic idea of how this stuff
works in order to proceed.
After all, ostensibly this writeup is about how to use PHYZZX
and is not a primer on \TeX .}
A really good thing to read to get an idea of the basic
things you can do with \TeX\ and to learn about the important control
sequences is a primer entitled {\bf First Grade \TeX\ \bf A Beginner's
\TeX\ Manual \rm by \it Arthur L. Samuel}.
This is short, readable and contains everything you need to
supplement this discussion of PHYZZX.
You can request a copy of this manual from the SLAC Library \hbreak

Since you are going to be both typist and editor it pays for
you to combine these jobs and mark up the manuscript at the
same time that you type it.
To be precise, this means that you want to type in equations
so that superscripts, \break \eject \noindent
subscripts, etc., are clearly indicated.
You also want to type chapter headings, subchapter headings, etc.,
in such a way that the font to be used, the space to be skipped
above and below the heading, etc. are all clearly indicated.
In general you want to tell the printer how to lay out the
resulting copy as you type it in.
This of course requires that you make many formatting decisions
and then use the basic \TeX\ control sequences in order to tell
it what to do.
It will come as no surprise to you that this can get very
complicated very quickly.
That's where PHYZZX comes in.
 
\section{What Is PHYZZX?}
 
PHYZZX is a {\it macropackage} which is designed to make typing papers
destined for Physical Review or Nuclear Physics as simple as possible.
In addition it allows you to type letters and produce memos without
knowing much about the way \TeX\ works.
 
The first question which arises at this point is {\it What is a
macropackage ?}, or for that matter {\it What is a macro?}.
Despite the name a {\it macro} is not something eaten on a
macrobiotic diet.
It is a name for a simple thing.
Unfortunately, this name has
been carefully designed by computerniks
to strike terror into the heart of occasional users and keep them
in their place.  (There is nothing more annoying than an
uppity occasional user.)
Basically a macro is a way of defining an entry in a dictionary
which is kept in the guts of the computer.
The computer uses this dictionary to
find the meaning of words which have been defined
using the control sequence {\bf \\def}.
A macropackage is, as the name implies, a package of macros (or
definitions of commands) which we can use to give complicated
formatting instructions to \TeX\ without having to go
to the trouble of typing everything out each time we want to
give the same instruction.
 
It follows from this discussion that PHYZZX is just a collection
of definitions which tell \TeX\ to do a well defined set of things
to make the text which follows look just the way you want it to look.
The best thing about a macropackage is that once it is written
you only have to know what happens when you
issue a given instruction;
you don't have to know how it is made to happen.
Although each of the commands which appear in the macropackage
cause apparently simple things to happen, making them happen can
get quite involved if you try to use the PLAIN version of \TeX .
 
\subsection{Why Create A Macropackage like PHYZZX ?}
 
Finally we get down to brass tacks.
We already pointed out that you, the person preparing the
manuscript, must to play the role of typist and editor.
As editor you have the job of telling the printer how large to
make chapter titles, what typeface to use for chapter titles,
how much space to skip above and below a chapter title, etc.
Having to give this set of instructions every time you want to
type a chapter title can get to be a pain in the neck.
Not only that, but imagine the problem of remembering exactly what
format you want for chapter titles, section titles, subsection
titles, etc., if -- as is the case with PHYZZX -- you use a different
format for each one.
Clearly, if one had to type all of this each time and keep all this
information in one's head one would probably choose not to use
\TeX\ at all.
 
This discussion raises another point, namely that if one did
not have a predefined set of macros to tell \TeX\ what to
do at a certain point then you would have one more job dumped upon
your shoulders.
In addition to being typist and editor you would have to be a book
designer.
That means that you would have to make all of the esthetic decisions
about the most attractive print to use for a given paper, the spacing
to use between lines, the best way to number equations and
the rest of that crap.
This can be an onerous task which the average user doesn't want to
have to deal with.
Moreover, everybody has his own esthetic criteria (even though some
people have more taste than others), so without
a macropackage, to
set the formats into predefined molds, there would be little
or no uniformity in the layout of papers coming out of SLAC.
While this would be no great tragedy, it could get confusing.
 
Okay, so PHYZZX is a macropackage which provides a dictionary
of editor's commands which allow one to easily format a
document for the printer.
It makes a set of esthetic choices for how these documents should
look and, in the interests of simplicity, doesn't make it trivial
for the casual user to mess around with these choices.
(Actually, this is not really true since there are many
ways in which PHYZZX can be tailored to your personal preferences,
but we will discuss that as we go along.)
The obvious question which comes up at this point is {\it Who
made all of these esthetic decisions?\/}.
In the interests of preserving the lives of the parties involved,
anonymity must be preserved.
Rest assured, however, it was a consultative process
and many people had an input into the final result.
Despite the fact that PHYZZX is an animal put together
by a committee, we think it does its job fairly well.
 
\subsection{ So, what does it do?}
 
The main job which PHYZZX is designed to do is to make
it easy to format SLAC preprints destined for submission to
Physical Review or Nuclear Physics.
Since these journals require different ways of handling line spacing,
footnotes, references, etc., PHYZZX you need to specify the journal
to which the preprint is to be submitted.
Actually, you only have to tell if the journal is going to be
Physical Review, since the default format is that for
Nuclear Physics.
This is because we, with our usual impeccable good taste,
decided that the Nuclear Physics format was a better
general purpose format.
If you don't like our decision write your own macropackage.
 
All kidding aside,
changing to Physical Review format is easy, all you have to
do is start your typing with
\tc{\\input phyzzx}
\tcon{\\PHYSREV}
Note, when you are typing a control sequence everything counts; i.e.,
\TeX\ cares about capital letters, small letters, spaces, etc.
Be careful to copy just what you see typed here or it won't work;
worse yet, it might work in an unexpected way.
 
In addition to formatting papers PHYZZX does a great job of
producing letters and memos.
In each of these cases it produces, by itself, the appropriate
letterhead and formats the text in a way appropriate to the
document at hand.
Since, however, we consider the preprint formatting capabilities
of PHYZZX to be of paramount importance, we will discuss them first
and turn to letters and memos when we have finished.
 
 
\chapter{STRUCTURING PREPRINTS}
 
A preprint is a document which eventually
will be submitted to a journal for publication.
In setting up PHYZZX we assumed that format of a preprint
is essentially fixed.
The size type to be used in the body of
the preprint is chosen so that when run off on the laser printer
and reduced for distribution it will be easily readable.
In addition, normally we skip
one and a half lines between lines of text.
We think this looks most attractive with the size type we are using
and makes the preprints a little shorter, saving paper.
To satisfy the requirements of journals like Phys.Rev. Letters
which specify the number of lines per inch which a
manuscript must have, you must use double spacing;
the command {\bf \\PHYSREV} automatically
takes care of this, as well as
a number of other things.
 
Concerning spacing and other parameters you may well ask
{\it How fixed is fixed ?\/}.
The answer varies.
For example,
since we realize that people like to play around with line spacing
to some degree, we have provided commands which we hope will
enable you to change the average interline spacing to
something closer to your heart's desire.
The commands which perform this wondrous feat are
\tc{\\singlespace}
\tcon{\\doublespace}
and
\tc{\\normalspace}
Obviously, {\bf \\doublespace} means twice {\bf \\singlespace};
but {\it What is the meaning of \bf \\normalspace \it ?\/}.
The answer to this question is that {\bf \\normalspace}
corresponds to a spacing between single and doublespace.
 
You might think, having read a little in the \TeX\ book,
that you can achieve the same thing by changing {\bf \\baselineskip}
and {\bf \\lineskip}.
In a sense you would be correct.
However, you should know that the commands {\bf \\doublespace}, etc.,
do more; this is because
they do different things depending upon the font and
format you are using.
If you want to do the same thing you will have to modify
a lot of basic \TeX\ parameters or the esthetic impact of the
document which emerges just won't be the same.
 
All of this is by way of a parenthetical comment since it won't
do you any good unless you know how to use the simplest version
of PHYZZX first.
 
\section{Chapters, Sections and Subsections}
 
\subsection{Chapters}
 
Most longer papers are divided into several parts in order
to make them easier to read.
These parts usually are preceded by headings or titles
which indicate the subject to be covered in discussion which follows.
Stylistically, several decisions have to be made about how
these headings are to be set in type.
You, as editor, have to tell the printer what to do.
 
We will refer to the major divisions of a paper as chapters.
In general each chapter has a heading.
Our choice as book designers has been to set this heading in
larger type and preface the text of the heading with a number.
The number is automatically increased each time you declare a
new chapter.
In addition, some extra space is skipped both above and below
each chapter heading.
All of this magic is at your disposal if you simply use the
{\bf \\chapter} command to indicate that the text you are
about to type is the heading of a chapter.
\storechap \storesec
To be precise, the way you use this command is to type
\tc{ \\chapter $\{$ {\it text} $\}$ }
where $\{$ {\it text} $\}$ stands
for the chapter name which you have to make
up and insert.
For example, the chapter title for this chapter was generated by
typing
\tc{\\chapter$\{$ {\it STRUCTURING PREPRINTS} $\}$}
 
Note, I chose to type the heading in capitals.
That's because I like the way it looks.
You certainly don't have to do that.
If you don't, but instead type
\tc{\\chapter$\{$ {\it Structuring Preprints} $\}$}
then you obtain \recallchap
\chapter{Structuring Preprints}
 
One thing to notice is the curly braces surrounding the text.
These braces are absolutely necessary.
They are grouping symbols which tell \TeX\ how much of the
text to follow is to be considered part of the chapter heading
and if they are omitted you will get a disastrous error message
saying something like \TeX 's capacity is exhausted.
Unfortunately, on the screen of a computer terminal,
these symbols are easy to confuse with ( \
and so you will have to be careful.
If you are in {\bf XEDIT}
you will be able to issue the command {\bf balance}.
This is an {\bf XEDIT} command defined by an exec file on the U
disk which counts matching pairs of curly braces.
It is helpful in that it tells you there is a problem, but
unfortunately it doesn't find the problem for you.
 
In general you won't want to play around with the choice of font
inside of a chapter heading and so, by default, you will
get a roman font.
However, you can play with it if you wish.
We have provided a series of control sequences, or editors marks,
which allow you to change between different fonts all of which
have essentially the same size.
Hence, if you type {\bf \\rm} you get the current roman font,
if you type {\bf \\bf} you get the bold face version of the current font,
if you type {\bf \\sl} you get a slanted version of the current font,
if you type {\bf \\it} you get an italic font, and if
you type {\bf \\tt} you usually get a typewriter font.
I say that you usually get a typewriter font because we do not
have typewriter available in all sizes of print.
When we don't PHYZZX makes a substitution of the same font at a different
size.
Another font for which this happens is {\bf \\caps} which is
a font \endpage \noindent which is made up of only capital letters.
This font distinguishes between upper and lowercase letters only by size.
As an example of switching fonts let us see what happens if we change
font inside the command chapter.
 
If you type \recallchap
\tc{\\chapter$\{$\\bf{ \it Formatting Text}$\}$ }
you get
\chapter{\bf Formatting Text}
If you type \recallchap
\tc{\\chapter$\{$\\sl {\it Formatting Text}$\}$ }
you get
\chapter{\sl Formatting Text}
If you type \recallchap
\tc{\\chapter$\{$\\it {\it Formatting Text}$\}$ }
you get
\chapter{\it Formatting Text}
\endpage
If you type \recallchap
\tc{\\chapter$\{$\\caps {\it Formatting Text}$\}$ }
you get
\chapter{\caps Formatting Text}
Finally, if you type \recallchap
\tc{\\chapter$\{$\\tt {\it Formatting Text} $\}$ }
you get
\chapter{\tt Formatting Text}
 
While all of this is very nice you should note that the font
used to set the chapter number does not change with the text.
This illustrates something about \TeX 's grouping symbols.
Since we put the control sequences for changing fonts inside the
braces, only the text inside the braces is affected.
That is, the change only occurs {\it locally}.
In general any change you make inside a pair of curly braces only
affects the material inside the braces, unless you force
the effect to persist.
(If you want to know how to do this look up the {\bf \\global}
command in the \TeX\ book.)
It follows, therefore, that if we want the number to change
we have to change the font before we give the {\bf \\chapter}
command.
 
\medbreak
If you type \recallchap
\tc{$\{$ \\bf \\chapter$\{$ {\it Formatting Text}$\} \}$}
you get
{\bf \chapter{Formatting Text}}
\endpage
If you type \recallchap
\tc{$\{$ \\sl \\chapter$\{$ {\it Formatting Text} $\} \}$}
you get
{\sl \chapter{ Formatting Text}}
\medbreak
If you type \recallchap
\tc{$\{$ \\it \\chapter$\{$ {\it Formatting Text} $\} \}$ }
you get
{\it \chapter{ Formatting Text}}
\goodbreak
If you type \recallchap
\tc{$\{$ \\caps \\chapter$\{$ {\it Formatting Text} $\} \}$ }
you get
{\caps \chapter{ Formatting Text}}
\medbreak
Finally, if you type \recallchap
\tc{$\{$ \\tt \\chapter$\{$ {\it Formatting Text} $\} \}$ }
you get
{\tt \chapter{ Formatting Text}}
\noindent Much better, no?
 
We have already mentioned that PHYZZX put extra space
above and below a chapter heading.
Since all of the chapter headings for this writeup
were generated using
the command {\bf \\chapter}, you only have to examine them
to see how \TeX\ handles these extra spaces.
 
Another remark worth making is that in the current incarnation
of PHYZZX you do not have to worry about chapter titles which
are too long.
The chapter macro is set up to split your line when necessary
and automatically center each line.
To accomplish this feat PHYZZX makes use of a control sequence
called {\bf \\titlestyle}.
The command {\bf \\titlestyle} is worth knowing about because
sometimes you want to be able to type in a longish amount of
material and want the various lines to be centered, not left or
right adjusted after each break.
Typing {\bf \\titlestyle$\{$ {\it text} $\}$} will accomplish this feat.
In addition,
if you don't like the way PHYZZX chooses to break the lines
you can force your desires upon the machine by inserting: the
command {\bf \\break}.
This command forces the line to break at the point where the command is
given.
The command {\bf \\nobreak} will stop the line from
breaking at an undesirable place, and the symbol \~ \ will
insert some unbreakable space between words.
This stuff is covered in the basic books on \TeX\ and we refer you to
there for details.
Combining these control sequences with the control sequence
{\bf \\titlestyle} allows you to {\it easily}
achieve many interesting effects.
For example, you can generate an invitation by typing \hbreak
{\bf \\titlestyle $\{$ \\it \it You are cordially invited \bf \\break
\hbreak
\it to the coming out party for \bf \\break \hbreak
\it the new macro package \bf \\break \hbreak
\\rm \it PHYZZX \bf \\break $\}$ } \hbreak
and obtain
\titlestyle {\it You are cordially invited \break
to the coming out party for \break
the new macro package \break
\rm  PHYZZX \break }
 
If you are really sharp, and I assume that you are, you will
have noticed that the type in which the invitation is set is larger
than the normal type.
Remember that I already told you that titles are set in larger
type than the basic text.
I also told you that the commands {\bf \\rm}, {\bf \\bf}, {\bf \\it},
etc., change the style of the font but leave it the same size.
What we have not discussed is how you change the size of the font
the way {\bf \\titlestyle} does with impunity.
Well, all things come to he who waits!
Now's the time to discuss this point.
 
Font sizes, as you learn from reading the \TeX book come in sizes
measured in a mysterious printer's unit call {\it points}.
You don't have to know what a point is, you only have to know that
most of the text in this writeup is twelve point type, the titles
are in fourteen point type and the footnotes are in ten point type.
It is possible for you to force \TeX\ to use a particular size
of type by saying {\bf \\tenpoint},{\bf \\twelvepoint} or
{\bf \\fourteenpoint}; in which case the obvious thing happens.
Thus, for example, if you change the typed instructions for generating
the invitation to read \hbreak
{\bf \\titlestyle $\{$ \\twelvepoint
\\it \it You are cordially invited \bf \\break
\hbreak
\it to the coming out party for \bf \\break \hbreak
\it the new macro package \bf \\break \hbreak
\\rm \it PHYZZX \bf \\break $\}$ }  \hbreak
you get
\vskip -\parskip
\titlestyle {\twelvepoint \it You are cordially invited \break
to the coming out party for \break
the new macro package \break
\rm  PHYZZX \break }
\endpage
\noindent and if you type \hbreak
{\bf \\titlestyle $\{$ \\tenpoint
\\it \it You are cordially invited \bf \\break
\hbreak
\it to the coming out party for \bf \\break \hbreak
\it the new macro package \bf \\break \hbreak
\\rm \it PHYZZX \bf \\break $\}$ }\hbreak
the result is
\titlestyle {\tenpoint \it You are cordially invited \break
to the coming out party for \break
the new macro package \break
\rm  PHYZZX \break }
 
\subsection{Sections}
 
Now that we know everything about generating chapters, we turn
to the problem of generating smaller subdivisions; namely,
sections and subsections.
 
\recallchap \recallsec
The numbering is done as $\{ chapter number\}.\{section number\}$ .
Each time you start a new chapter, the section numbers restart from
1.
You have already seen many examples of the results produced by
the section macro in this writeup.
As in the case of the chapter macro all of the numbering is taken
care of automatically.
To accomplish the feat of generating a new section heading you type
\tc{\\section $\{$ {\it section heading} $\}$ }
For example, if you type
\tc{ \\section $\{$ {\it New Section} $\}$ }
you get
\advance\sectionnumber by -1 \section{ New Section }
As in the case of chapter headings you can play with the
fonts if you insist; however, remember that the space above and
below chapter and section headings have been carefully matched
to our choices of fonts.
If you play too much, the esthetic balance of the final copy
won't be the same.
 
\subsection{Subsections}
 
The smallest subdivision for which we have a formal macro
defined is a subsection.
Our choice has been to make subsections unnumbered and underlined.
When you type the command {\bf \\subsection
$\{$ {\it subsec.heading} $\}$ }
you get the sort of heading which introduces this paragraph.
All of the control sequences, {\bf \\chapter}, {\bf \\section} and
{\bf \\subsection} force the start of a new paragraph, so in principle
you do not have to skip lines as you type in text.
However, from the point of being able to proofread your
typed copy in order to make corrections, not skipping lines
can be a disaster.
 
The underlining of the text in the section macro is accomplished using
the control sequence
\tc{\\undertext $\{$ {\it text} $\}$ }
This is a command worth knowing about, but in general using italics
is a better way to emphasize text.
 
This completes our discussion of the macros which handle the
generation of titles for the major subdivisions of the usual paper.
 
\section{Other Subdivisions: Appendices and Acknowledgements}
 
In addition to chapters, sections and subsections, papers tend
to have auxiliary junk attached.
This extra junk is usually called either
acknowledgements or appendices.
To save you the bother of figuring out which font sizes and spacing
choices are necessary to make these appendages
consistent with the rest of the paper we also have
control sequences to generate headings for them.
Typing the command
\tc{ \\ack }
generates the line
\ack
Note the beauty of the typeface and the precisely chosen amounts of
extra space which gracefully offset the title generated with this
simple command.
Once again, for the Philistines among you, you can play with
the fonts using the commands {\bf \\bf}, {\bf \\sl}, etc.;
however, let the esthetic violence you do to the manuscript
be on your own head.
 
Generating appendices presents us with a slightly more complex
situation and so you get more choices as to how to proceed.
The questions which arise at this juncture are
{\it How many appendices will there be ?\/} and
{\it How do you want them numbered ?\/}.
Clearly, if there is to be only one appendix then the choice is
simple.
In that event you generate a lovely heading by simply typing
\tc{ \\appendix }
which causes \TeX\ to generate the line
\appendix
If there are to be many appendices and you want to number them
in any way which suits you, you only need type
\tc{\\Appendix$\{$ {\it text} $\}$ }
note the capital letter appearing as the first letter of this control
sequence.
Remember, \TeX\ cares about upper and lowercase, so this is a
different command from { \bf \\appendix}.
 
Typing
\tc{\\Appendix$\{$ {\it A} $\}$ }
generates
\Appendix{A}
\noindent Typing
\tc{ \\Appendix$\{$ {\it I} $\}$ }
generates
\Appendix{I}
\endpage
\noindent and typing
\tc{ \\Appendix$\{$ {\it 1} $\}$ }
generates
\Appendix{1}
 
\recallchap \recallsec \advance\chapternumber by 1
\def\chapterlabel{3.}
\advance\sectionnumber by 1
\def\sectionlabel{\number\sectionnumber \quad}
 
This completes the discussion of the basic commands which generate
division headings.
Now we turn to a discussion of the special commands which
PHYZZX has included to allow you to tailor the way in which
these macros handle numbering conventions.
 
\section{Controlling the Way Chapters are Numbered}
 
The discussion to follow is really not necessary if what you want to
learn is how to use PHYZZX to type a paper.
This section is devoted to making PHYZZX do something out of
the ordinary; i.e., something it ordinarily doesn't want to do.
 
\subsection{Playing With Numbers}
 
There will be times when you want to print out just a
piece of a paper either because it is long, or because (as I
understand is the case for that strange group of people called
{\it experimental physicists}) many people are working on different
chapters (perhaps even sections) of the same paper.
In this event you probably want the chapter and section numbers to
print correctly when you are proof reading so that you don't get
confused.
Rest easy, this can be done.
PHYZZX defines two quantities which it updates and refers to when
it needs chapter and section numbers.
These quantities are called {\bf \\chapternumber} and
{\bf \\sectionnumber} (big surprise!).
You, as the editor, can tell PHYZZX to set these numbers to a
specific value, say 7, by typing
\tc{\\chapternumber$=$7}
or
\tc{\\sectionnumber$=$7}
Note that for the first time you have encountered an $=$
sign occurring in a statement to \TeX .
You will encounter this sort of syntax many times,
in general when it occurs it will be because it is the natural
way to write something.
 
Once you get involved in fooling with chapter and section numbers
there are a few things you have to know.
Both the {\bf \\chapter} and {\bf \\section} macros increase
the respective chapter or section number by 1 before they print
anything.
Thus, if you want to get a chapternumber like 7 you set
\tc{\\chapternumber$=$6}
The same is true for setting the section number.
If you are so perverse as to start in the middle of a chapter, then
when you set the section number you must also set
the chapter number, since it appears as part of the section
heading.
Actually, the quantity which appears in the section heading is
called {\\bf \\chapterlabel} and to set it you have to say
\tc{\\let\\chapterlabel={\it 6}}
or whatever label you want instead of 6.
This extra step is required because we really don't think its
such a great idea to start in the middle of a chapter  and
so didn't bother to make it too trivial to do so.
If you are starting a chapter, then you don't have to worry
about setting the section number since the command {\bf \\chapter}
automatically resets the section number to 0.
 
\subsection{Changing Styles}
 
Another way you might want to modify the way PHYZZX handles divisions
is to have it number chapters using letters, or roman numerals,
instead of arabic numerals.
Although this defeats the purpose of establishing some sort
of uniformity of style for preprints, etc., it is possible to do.
This feature was added to PHYZZX because we recognize that some
folks, particularly experimentalists, just can't leave well
enough alone.
The mood of people like this begins to verge upon hysteria if
they don't have knobs to twiddle and buttons to push.
For this small number of benighted souls there exists the
special command called {\bf \\chapterstyle}.
You change the way in which PHYZZX numbers chapters by saying
\settabs 2 \columns
\+ {\bf \\chapterstyle$=$$\{$\\alphabetic$\}$}& to get
the l.c. letters a,b,c,$\ldots$ \cr
\+ {\bf \\chapterstyle$=$$\{$\\Alphabetic$\}$}& to get
the u.c. letters A,B,C,$\ldots$ \cr
\+ {\bf \\chapterstyle$=$$\{$\\roman$\}$} & to get
the l.c. roman numerals i,ii,iii,$\ldots$ \cr
\+ {\bf \\chapterstyle$=$$\{$\\Roman$\}$} & to get
the u.c. roman numerals I,II,III,$\ldots$ \cr
 
There is one more option open to you, that is to have all
chapters, sections and subsections unnumbered.\foot{Note that
this implies that all equations will automatically be sequentially
numbered}
To select this option you begin your file with the command
\tc{\\unnumberedchapters}
This is not too difficult, but it is long to type.
 
One final remark.
We have not made it possible, other than shutting it off
completely, for you to change the style used when numbering subsections.
All you get is {$ chapterlabel.section number $} no matter what you
do.
Moreover, the section number is always an arabic numeral.
If you don't like this, write your own section macro.
(This isn't as bad as it sounds.  We'll discuss doing this sort of
thing at the end of this writeup.)
 
\chapter{DISPLAYED EQUATIONS: NUMBERING AND NAMING THEM}
 
We have now discussed the macros available for defining the basic
parts of a paper and appropriately titling them.
Now let us turn to the most important
stuff -- other than text -- which appears in each section; namely
equations.
If you've done your homework and read Knuth or {\bf First Grade
\TeX\ } you know that equations are typed in {\it math mode}
and that you let \TeX\ know that you are in math mode by
typing either \$ or \$\$ .
Enclosing an equation inside a pair of single \$  signs
puts it in ordinary mode; enclosing the same equation between
matching pairs of \$\$ signs puts it in display mode.
Regular math mode is used for inserting equations into a line of
text.
Since you have done your homework we don't have to say
anything about this, since PHYZZX doesn't play with ordinary math mode
at all.
Display mode is used for generating equations which are to stand out
from the ordinary text.
It allows you to type  \hbreak
{\bf \$\$} {\it (x+y)(x-y) = x\^\ 2 - y\^\ 2 }{\bf\$\$ } \hbreak
in order to get
$$ (x+y)(x-y) = x^2 -y^2 $$
This is called a displayed equation.
 
Displayed equations are used in all journals and are usually
numbered.
In PLAIN \TeX\ there is a built in
capability for allowing you to generate
equation numbers; it is the macro {\bf \\eqno}.
If you type \hbreak
{\bf \$\$ \it  (x+y)(x-y) = x\^\ 2 - y\^\ 2 \bf \\eqno({\it 13}) \$\$ }
you get
$$ (x+y)(x-y) = x^2 -y^2 \eqno(13) $$
This example shows what the command {\bf \\eqno} does. It makes
the material appearing to the right of this command into
a label for the displayed equation and sticks it in the right hand
side of the line.
There is also the PLAIN \TeX\ command {\bf \\leqno} which does the same
thing but puts the equation number on the left.
For example, typing \hbreak
{\bf \$\$ \it 7x+12 = 24 \bf \\leqno ({\it 13}) \bf \$\$ } \hbreak
produces
$$ 7x + 12 = 24 \leqno(13) $$
 
{\it So}, you ask, {\it what does PHYZZX have to do with this?}
Well the answer to that question depends upon who you are.
If you are typing someone else's handwritten manuscript which is
in final proofread form, then these macros for putting in
equation numbers are all you need.
If, however, you are the author of the paper, typing it in yourself,
either from a rough copy or composing it directly at the
terminal, then these two commands leave a great deal to be desired.
 
To begin with, if you are anything like me, when composing
at the typewriter you usually forget the number of the last
equation you have typed.
Of course you can always go back and look it up, but this is time
consuming and sometimes difficult to do.
In addition if, as is usually the case, you expect the manuscript
to be changed after it is typed, then it is highly likely
that equations will be added, deleted and moved around.
In that case, if you have used {\bf \\eqno} or {\bf \\leqno}
you will have to go through the text and change all of the
equation numbers and all references to those numbers each time
there is a revision.
Clearly this can get to be a big nuisance.
Wouldn't it be nice if \TeX\ would just take care of numbering
all of the equations properly each time it prints the manuscript
taking into account all of the revisions automatically.\hbreak
\centerline{{\it Joy of joys} it can be done!}
 
\section{A Simple Solution to Numbering Equations}
 
PHYZZX has a macro {\bf \\eq} which can take care of this chore for
you automatically.
All you have to do is type \hbreak
\tc{ \$\$ \it x + y = {\bf $\{$} 2 {\bf \\over} (x - y) {\bf $\}$}
\bf  \\eqno\\eq \$\$}
to get \hbreak
$$ x + y =  {2 \over (x-y)} \eqno\eq $$
and you will have automatically generated an equation number.
The question is, {\it What sort of equation
number will you generate ?\/}.
Once again, this is a question of style.
If you are in the Phys.Rev. format, or in the default Nuclear Physics
format then the equation label is of the form
{ \it chapterlabel.equation number}.
Equations are numbered sequentially within each chapter, but
when you change chapters the chapter number is increased by
1 and the equation number is reset to 1.
If you have chosen the format with unnumbered chapters and sections,
then {\\eq } will automatically generate sequential equation numbers.
As far as we are concerned this is the most satisfactory way of
numbering things.
For short papers, i.e. those with only one chapter, choose the unnumbered
chapter format and all of your equations will be numbered sequentially;
for longer papers, i.e. those which call for dividing them into
chapters, numbering the equations by their chapter and number within
the chapter makes it easier to refer to them.
Sometimes, however, either out of perversity or because a paper
has many chapters but very few equations, an author wishes to
choose the format with numbered chapters but sequential equation numbers.
This will happen if, before entering the first equation in your paper
you type the command {\bf \\sequentialequations}
Hence, in the default mode, typing
\tc{ \$\$ \it 7x + 11x\bf \^\ \it 2 = 50 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 3x +   x\bf \^\ \it 3 = 85 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 4x +  8x\bf \^\ \it 7 = 12 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 7x + 4x\bf \^\ \it 2 = 0 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it  x + 21x\bf \^\ \it 5 = -5 \bf \\eqno\\eq \$\$ }
yields
\equanumber=0
$$  7x + 11x^2 = 50 \eqno\eq $$
$$  3x +   x^3 = 85 \eqno\eq $$
$$  4x +  8x^7 = 12 \eqno\eq $$
$$  7x +  4x^2 = 0  \eqno\eq $$
$$   x + 21x^5 = -5 \eqno\eq $$
If, however, you first type {\bf \\sequentialequations};
then typing \hbreak
\tc{ \$\$ \it 7x + 11x\bf \^\ \it 2 = 50 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 3x +   x\bf \^\ \it 3 = 85 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 4x +  8x\bf \^\ \it 7 = 12 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it 7x + 4x\bf \^\ \it 2 = 0 \bf \\eqno\\eq \$\$ }
\tcon{ \$\$ \it  x + 21x\bf \^\ \it 5 = -5 \bf \\eqno\\eq \$\$ }
yields
\sequentialequations
$$  7x + 11x^2 = 50 \eqno\eq $$
$$  3x +   x^3 = 85 \eqno\eq $$
$$  4x +  8x^7 = 12 \eqno\eq $$
$$  7x +  4x^2 = 0  \eqno\eq $$
$$   x + 21x^5 = -5 \eqno\eq $$
 
Since you are an astute reader you have no doubt noticed
that what I have told you to this point only solves half of the
problem.
While {\bf \\eq} automatically generates equation numbers
which, each time you run the paper through \TeX\ ,
are automatically updated to conform to the order in which
they appear in the text, we have no a priori way of knowing what these
numbers are.
The question is, {\it How do we get hold of these numbers so that
we can refer to them in the text?\/}
Well, {\bf \\eq} provides a partial solution to this problem by
definiing the control sequence {\bf \\?} a synonym for that
number each time it is invoked.
Hence, typing {\bf \\?} at any point in the text causes \TeX\ to
print the number of the last equation in which you used the
command {\bf \\eq}.
For example by typing {\it equation \bf \\?} we cause \TeX\ to print
equation \? , which is the number of the last equation
appearing in our examples.
The only thing wrong with this solution is that the meaning of
the symbol {\bf \\?} changes each time you invoke {\bf \\eq},
so what happens if you want to refer back to an equation
at several different points in the text?
 
\section{Naming Equations: A Powerful Tool}
 
In order to make it possible to refer back to a specific equation
without knowing its number, PHYZZX has a way of giving the equation
a symbolic name, like {\bf \\?}, which will always stand for the
number of that equation.
The macro which accomplishes this feat does this at the same time
it generates (and prints) the number associated with this
equation.
Since this command does just one more thing than the command
{\bf \\eq} does, we have given it a name which is just one
letter longer; the name is {\bf \\eqn}.
To use {\bf \\eqn} you type
\tc{ \\eqn\\{\it equation\_name}}
\equanumber=6
Note carefully the \\ appearing before the equation name inside the
braces.
This backslash must always precede the name itself because you
are using {\bf \\eqn} to define a new control sequence and, as
we have already noted, control sequences always start with a \\ .
Also note the grouping symbols.
They tell \TeX\ to include everything in the braces as the
equation name and they are necessary.
To use this command you type something like \nextline
{\bf {\it the value of} \$ \\pi \$ {\it is}} \nextline
\tc{ \$\$ \\pi \\approx {\it 3.14159 } \\eqn\\{\it valueofpi}  \$\$ }
to obtain \nextline
 
the value of $\pi$ is
$$ \pi \approx 3.14159 \eqn\valueofpi $$
If you now type       \nextline
{\it the circumference of a circle is given by} \nextline
{\bf \$\$ {\it 2} \\pi {\it r}
\^\  {\it 2} \\eqn\\{\it circumference} \$\$ }\nextline
you define a new equation number and a new name.
The result of this is  \nextline
 
\noindent the circumference of a circle is given by
$$  2\pi r^2 \eqn\circumference $$
If we now type {\bf \\valueofpi} we get \valueofpi ,
if we type {\bf \\circumference} we get \circumference .
 
A little thought will convince you that this ability to name
equations is a very powerful time saving tool.
By giving names to equations you are able to refer to them
at will without ever giving a thought to the number they
will be assigned when the paper is printed.
If you use the command {\bf \\eqn\\{\it name}} to
deal with the numbering problem, then the number assigned to the
equation and all references to the equation will always be correct.
It won't matter if you delete equations, add equations, move
equations around, or decide to switch from the normal conventions
for numbering equations to sequential numbering, etc.
 
\subsection{Restrictions on Equation Names}
 
There are only a few simple rules you should observe when giving
names to equations using the command {\bf \\eq}
\pointbegin
First, the name has to be proceeded by a \\ as we already noted
\point
Second, the rest of the name has to be all letters.
{\it No numbers are allowed\/}.
You may however use upper and lowercase letters, and names can
be arbitrarily long.
Everyone seems to have his own favorite way of naming equations
in order to facilitate referring back to them later.
I invite you to play around with this until you find a scheme
which makes you comfortable.
\point
Third, try to remember to always use a different name for each
equation.
Neither \TeX\ nor PHYZZX will warn you if you give two equations
the same name.
They will quite happily change the meaning of the
previously defined name to mean the number of the last equation
to which you have given that name.
If you wish this to happen, o.k., however be sure that is what you
want or you will be in for some surprises later.
\point
Finally, {\it never use the name of any macro for an equation name},
this road surely leads to disaster.
For example, if you accidentally type {\bf \\eqn\\bf}
you not only change the previous meaning of {\bf \\bf} but you
also mess up any macro which uses that control sequence.
 
As an example of this I note that the names {\bf \\herman},
{\bf \\Suzanne}, {\bf \\duMMy } are all good names; however,
{\bf \\jerk3}, {\bf \\don't} and {\bf \\sl} are not.
There is one exception to this rule, you can give the name {\bf \\?}
to an equation, which is what the macro {\bf \\eq} does.
This is useful only if you intend to use it as a temporary name
for an equation that will be referred to once or twice before
the name is redefined.
If you really want to give use numbers for you equation names
roman numerals are all right.
You can name equations {\bf \\eqi},{\bf \\eqii},$\ldots$,
{\bf \\eqix }, etc.
 
\section{Other Macros For Naming Equations}
 
We have already noted that \TeX\ allows you to put equations
on the left hand side of a line using the macro {\bf \\leqno}.
For this reason, we too need a version of the naming macros
which do the same thing.
The obvious name for such a macro would be {\bf \\leqn}
and it is invoked by typing
\tc{\\leqn\\{\it equation.name}}
If you include this in an equation the number comes out on the left.
 
In addition to this obvious addition to the macro set
there are macros meant to be used for the automatic numbering of
aligned equations.
To learn about aligned equations you should read in the \TeX book
or in {\bf First Grade \TeX }.
Assuming that you have done so, let me remind you how about how
aligned equations are generated, in order to set the stage for
explaining how the macros {\bf \\eqinsert}, {\bf \\leqinsert},
{\bf \\mideqn} and {\bf \\midleqn} work.
 
Aligned equations are, as the name implies, a set of equations
which appear one after the other.
In order to make the spacing between these equations look nice
and in order to make them line up so as not to look messy
PLAIN \TeX\ introduces the macro {\bf \\eqalign}.
This macro produces a list of equations which are aligned with
respect to some common feature of each equation, for example
an $=$ sign.
As with single displayed equations \TeX\ allows you to number these
sets of equations as if they are a single equation by using the
commands {\bf \\eqno}, {\bf \\leqno}.
PHYZZX, too, is kind and permits exactly the same thing; to do this you
use the commands {\bf \\eqn} and {\bf \\leqn}.
Since {\bf \\eqalign} is a macro whose argument is the text of the
equations, the way to use {\bf \\eqn}, etc. is to type them
{\it after} the right $\}$ which closes the {\bf \\eqalign}    %{
command.
For example, typing \nextline
{\bf \$\$ \\eqalign$\{$ \\cos $\{$ \\pi \\over {\it 6} $\}$\\ = \& \\
\\sqrt$\{${\it 3/4}$\}$ \\cr \nextline
\\cos$\{$\\pi\\over{\it 4}$\}$\\ =\&\\ \\sqrt$\{${\it 1/2}$\}$ \\cr
\nextline
\\cos$\{$\\pi\\over{\it 3}$\}$\\ =\&\\ \\sqrt$\{${\it 8}$\}$ \\cr $\}$
\\eqn\\trig \$\$ }\nextline
yields
$$ \eqalign{\cos{\pi \over 6}\ = &\ \sqrt{3/4} \cr
\cos{\pi\over 4}\ = &\ \sqrt{1/2} \cr
\cos{\pi \over 3}\ =&\ \sqrt{8} \cr} \eqn\trig $$
 
\subsection{Things to Remember About {\bf \\eqalign}}
 
\pointbegin
The entire argument of {\bf \\eqalign} must be enclosed in braces.
Successive rows of the equation must be separated by the control
symbol {\bf \\cr} to tell \TeX\ to make a carriage return.
\point
Every row contains two parts (or {\it templates}) separated
by the special tabulation symbol \&.
This symbol tells \TeX\ what character you want to line up in each
line of the set of equations.
If you want half of some of the lines to be empty that is all right,
but the symbol \& must always appear.
Left and right braces within a {\it template} must balance separately.
\point
PLAIN \TeX\ sometimes puts aligned equations too close together.
If you want to force {\bf \\eqalign} to spread the lines apart
somewhat there is a special control symbol for doing this.
All you have to do is type {\bf \\cropen$\{${\it space}$\}$}
instead of {\bf \\cr} at the end of each line.
For example, {\bf \\cropen$\{${\it 12pt}$\}$ } will force
the lines 12pt further apart.
The control sequence {\bf \\crr} is an abbreviation for
{\bf \\cropen$\{${\it 10pt}$\}$}.
 
Although it is not obvious from the previous example, {\bf \\eqalign}
won't always put the equation number where you would like it.
For example, if one of the equation lines is very long and
pushes into the right hand margin, then {\bf \\eqalign} will
put the equation number on a separate line below the last equation
in the set.
If, as often happens, there is only one or two long lines and
there is room on one of the other lines for an equation number
you can force \TeX\ to put it there if you wish.
The way to do this is to use the PLAIN \TeX\ control sequence
{\bf \\eqinsert} immediately following the {\bf \\cr} or
{\bf \\cropen} ending the line you wish to have the equation on.
If you type \nextline
{\bf \$\$} $\ldots$ {\bf =\&} $\ldots$ {\bf \\cr \\eqinsert$\{$
{\it equation.number}$\}$ \$\$ } \nextline
then you get the equation number you specify on the line
indicated.
The corresponding PHYZZX macros which allow you to do this
while at the same time automatically generating a name and number
for the aligned set of equations are
\tc{\\mideqn\\{\it name}}
If you don't want to name the equation at the same time that
you automatically generate a number for it you can simply use
\tc{\\eqinsert\\eq}
 
\subsection{Numbering Aligned Equations Independently}
 
Sometimes you will wish to generate a set of aligned equations
but refer to each of them individually.
In this case you will wish to be able to number them independently.
PLAIN \TeX\ provides the control sequence {\bf \\eqaligno}
to handle this eventuality.
The command {\bf \\eqaligno} works like {\bf \\eqalign}
except that each equation line consists of three
parts (or {\it templates\/}) separated by the character \&.
The third template is where you put the appropriate label for
that line of the set of equations.
If you wish to number each equation line sequentially without
generating a name, then all you have to do is type \nextline
{\bf \$\$  \\eqaligno $\{$ {\it junk} \& {\it more junk} \&
\\eq \\cr $\}$ \$\$ }\nextline
If, however, you wish to name each line separately
you {\it may not} use the macro {\bf \\eqn}.
It will not work and will give you a peculiar message of the form
{\it you cannot use {\bf \\eqno} inside {\bf \\eqalign}}.
To name individual lines of aligned equations the correct macro
to use is {\bf \\eqnalign $\{$ \\{\it name} $\}$ } as the
entry for the third template followed by the command {\bf \\cr}.
The same command will work in {\bf \\leqaligno} which works
in exactly the same way as {\bf \\eqalign} but puts the contents
of the third template to the left of each equation instead of to
the right.
In general, {\bf \\leqaligno} causes more difficulties than
{\bf \\eqaligno} and you should read about it in the \TeX book
before using it.
 
\chapter{REFERENCES, FIGURE CAPTIONS AND TABLE CAPTIONS:
THEIR NAMING AND NUMBERING }
 
\section{References: Stuff Which Comes at the Back}
 
To this point we have discussed the partitioning of a document
into it's major parts, and the automatic numbering and naming
of equations.
We now come to the question of generating references.
In general a reference is signaled by attaching a
label or reference mark, i.e.
either a superscripted number or a superscripted number
enclosed in delimiters (e.g., braces, brackets or parentheses),
to a specified word in the text.
This number indicates that in the back of the document, on a page
(or pages) labelled REFERENCES, one will find a corresponding
chunk of text prefaced by the same number.
This text will usually be
a reference to work published in some journal
or some comment which is only marginally relevant to the subject
being discussed.
Your problem as typist and editor is to generate the appropriate
number, attach it to the desired word and then type the desired
text into a separate file of text at the same time numbering it
with the corresponding number.
You therefore are faced with several formatting decisions;
namely, how to attach the reference number to the word in
the text, and how to format the references when they are typed
in the back of the paper.
Clearly, there is a real need for a macro
to help you handle this dull and repetitive chore.
 
\subsection{What features should such a macro possess ?}
 
First it should handle the task of
attaching the desired number to the designated word, and
then it should file away the pertinent text in a form which will
allow it to be printed at the end of the paper.
In addition to the mechanical act of attaching the reference mark and
sending the text to another page, we would also like it
to automatically generate the number for us; so that we don't have to
constantly refer back to the number of the last reference
inserted.
As in the case of equations, this would be nice, since then
the numbering will automatically come out correct even if we
add, delete or move references around.
Finally, since one often cites the same reference
in many places in the text, it would be nice for the macro to
allow us to name a reference (in the same way we named equations)
so that we can cite it without ever knowing exactly
what number PHYZZX has assigned to it.\nextline
 
\centerline{PHYZZX \it has the macro capability to do all of this
and more.}
 
Since, however,
there are may different ways in which people like to
generate and cite references we had to make the commands for
carrying out these tasks more flexible than those which we
have been discussing to now.
For this reason there are more of them to learn about
and their syntax is a little more complicated.
We will take them one at a time in increasing order of
generality.
 
\subsection{Single References}
 
Let us deal with the simplest case first.
Suppose you wish to generate a reference, mark the appropriate word
and save the indicated text for printing in the back of the paper.
The command used to accomplish this feat is
{\bf \\ref}.
The syntax of this command is
\tc{ \\ref$\{$\it text$\}$}
where the indicated text is the material which you wish to have
appear in the back of the paper.
For example if you type\ref{This is the place you want to put a
reference}{\bf \\ref$\{$ \it This is the place you want to put a
reference \bf $\}$}; then PHYZZX will, as you see, generate a
reference number, attach it to the word immediately preceding
the macro command and store the text in a file on your A disk.
Each time you invoke the macro {\bf \\ref} it increases the
reference number by 1 and adds the next reference to the file on
your A disk.
Anytime that you wish to print this file all you have to do is
type the command {\bf \\refout}.
Normally, you would wait to do this until the end of the document;
however, to see what happens we will now type {\bf \\refout} to
obtain
\nobreak
\refout
 
\referencecount=0
Note, that the simple command {\bf \\ref} is like the command {\bf \\eq}:
it automatically numbers the reference and stores it away,
however it does not allow you the freedom of naming it.
It is like {\bf \\eq} in another way;
like {\bf \\eq} it automatically
gives the reference the name {\bf \\?}.
This allows you to refer to the last reference until
you do something to redefine {\bf \\?}.
Clearly, this command has only
limited flexibility and one needs a more sophisticated command
to allow you to individually name each reference.
The command which does this is {\bf \\Ref}; the syntax for this
command is
\tc{\\Ref\\{\it name}$\{${\it text of reference}$\}$}
where {\it name} is the name you wish to assign to this
reference and {\it text} is the material which you wish to have
appear on the page of references at the back of the document.
To use the command {\bf \\Ref} you simply begin typing the
appropriate reference immediately following the word to which
the reference number is to be attached.
For example if you type \nextline
$ \ldots $ {\it this is the result obtained by Banks and
Kaplunovsky{\bf \\Ref\\}junkname{\bf $\{$}T.\~\ Banks
and V.\~\ Kaplunovsky \bf $\}$}
you get \nextline
$\ldots$ this is the result
obtained by Banks and Kaplnovsky\Ref{\junkname}{T.~Banks
and V.~Kaplunovsky}\nextline
Note that the word Kaplunovsky has a superscripted version of the
current reference number attached to it and the text has disappeared.
The text is stored away in a file called
{\bf referenc.texauxil}.
This file is automatically stored on your A disk
when the \TeX\ file is processed.
Once again, to print this stuff we type {\bf \\refout}
 
\refout
 
\noindent If we wish to refer to this reference we need only type
{\it Ref. {\bf \\junkname}} to obtain Ref.\junkname .
Note that when you type {\bf \\junkname} you do not automatically
get a space after the number generated, even if you typed one.
This is because \TeX\ eats a space which appears after a control
sequence.
If you want a space to follow the number you should type
{\bf \\junkname\\ \quad }; i.e., {\bf \\junkname} followed
by a {\bf \\ \it (space)}, which is \TeX 's control sequence for an
extra space.
 
\subsection{Gaining Ultimate Control of Referencing}
 
Recapping, we see that
the command {\bf \\Ref} basically does for references what {\bf \\eqn}
does for equations.
Ordinarily, {\bf \\Ref} is the most convenient version of the
reference command and will be the one you will use most
often.
There will be situations, however, where you wish to generate a named
reference without generating its reference mark.
For example, you may be typing a formula, or a footnote and wish
to put the superscripted reference mark inside the footnote or formula
(or for that matter, inside some {\bf \\hbox} which you are
defining).
You must be careful because the command
{\bf \\Ref} cannot be used in these situations.
This has to do with the way in which it goes about doing its job.
You really don't have to know the reasons why it won't work,
you just have to know it won't.
This problem is easily solved if you know how to use the most
flexible form of the reference command; namely, the command
\tc{\\REF\\{\it junkname}$\{$ {\it text }$\}$}
As you see the syntax of this command is identical to {\bf \\Ref}
and in fact, it does almost exactly the same thing.
It generates a dummy name ({\bf \\junkname}) and writes the text
material into the file {\bf referenc.texauxil}.
The difference is that when {\bf \\REF} is finished it does not
attach the reference mark to the preceding word.
To attach the reference mark to a specific word you type the command
{\bf \\refend} immediately following that word.
Basically, what {\bf \\Ref} does is invoke the command {\bf \\REF}
immediately followed by the command {\bf \\refend}.
Dividing the reference generating command from the
command which attaches the reference mark
solves all of the aforementioned problems.
If you wish to put a reference in a forbidden place, like a footnote,
or hbox, or formula, all you have to do is use {\bf \\REF}
somewhere before you enter the forbidden territory and then use
{\bf \\refend} immediately following the place where you want the
reference mark.
 
\subsection{Generating Your Own Reference Marks}
 
Since the referencing commands are the ones which are
most often played with (because
so many people have their own styles for referencing things) it
is worth spending a few moments giving you a better understanding
of the various subcommands which go into their construction.
First, you should know that the current value of the number
assigned to the last reference
is filed away under the name
{\bf \\referencecount}.
To get hold of this number you type
\tc{\\number\\referencecount}
and then \TeX\ will type out the current value of this number.
PHYZZX attaches this number to a word by invoking
the command {\bf \\refmark}.
The syntax of the control sequence {\bf \\refmark} is
\tc{\\refmark$\{$ {\it number or name of reference}$\}$ }
When this command is issued PHYZZX tells \TeX\ to generate a
superscripted version of the material appearing inside the braces
and attach it to the word immediately preceding the place where you
typed this control sequence.
It is not advisable to leave spaces between the word
and the command {\bf \\refmark} (or for that matter {\bf \\ref, \\Ref}
and {\bf \\refend}),
because if space is left it might creep into the text.
The command {\bf \\refmark} does one more thing, it changes the
appearance of the reference mark depending upon whether the paper
is in Nuclear Physics or Physical Review format.
 
Since I have referred to {\bf \\refmark} as a subcommand
it is only fair to give an example of how it is used.
One place is in the definition of the command {\bf \\refend}.
PHYZZX defines the command {\bf \\refend} to mean
\tc{\\refmark$\{$\\number\\referencecount$\}$}
Using {\bf \\REF} to define a reference outside
of a forbidden region and using {\bf \\refend} inside this region
to generate the reference mark provides only a partial solution to the
problem we have been discussing.
This is because {\bf \\refend} causes the current value
of {\bf \\referencecount} to be printed.
If, for some reason you wish to delay the printing of
several reference names; or, if you wish to mix and match various
references and stick them in a single reference mark, you can
do this by typing {\bf \\refmark$\{$ \\junkname} $\ldots$ {\bf $\}$}
In this way you can gain all but stylistic control
of your reference marks.
It is still true that {\bf \\refmark} changes the form of the
reference mark depending upon whether the paper is headed for
Phys.Rev. or Nucl.Phys.
 
To gain total control of your reference marks
you need to use the command {\bf \\attach}.
The syntax of this command is
\tc{\\attach$\{$ \it stuff \bf $\}$}
What {\bf \\attach} does is put {\it stuff} into math mode,
make a superscript out of it and attach it to the word that
comes before.
It also spaces from that word so as to make the attached
quantity look most natural.
The {\bf \\attach} command does nothing at all to the reference
mark and it is independent of the format of the paper.
 
\subsection{Multiple References}
 
You have now learned all you should know about generating
single references and taking complete control of the way in which
they generate reference marks.
However, you still do not know everything about the
way in which PHYZZX can handle references.
This is because we have not yet discussed the question of
multiple references.
 
{\it What is a multiple reference?} and {\it Why should I care about
multiple references?} you ask.
Good question!
In principle you don't need to care about them at all.
You already have the basic tools for handling any referencing problem
should the need arise, all you need to do is
use the commands {\bf \\REF} and {\bf \\refmark}.
Nevertheless, since multiple references occur frequently, especially
in experimental papers, they merit a special
construct to make them simpler to handle.
 
The problem of generating multiple references comes up
when you reach a point in the text where you wish to
add a reference to several authors and at the same time
you do not wish to have this saved as a single reference.
This may happen for several reasons, the principal reason
being that you may wish to refer to some of these references
individually at a later point in the text.
In this case there exists a set of commands which allow you
to do this.
These commands allow you to tell \TeX\ that the material to
follow will define and name several references.
They assign a number to each of these references,
store them away individually and then attach the reference mark \nextline
$\{$ {\it number of first ref. in set -- number of last ref. in set}$\}$
\nextline
The presence or absence of delimiters (in the form of brackets) depends
upon whether or not you have typed {\bf \\PHYSREV}.
The commands which perform this service are
\tc{\\REFS\\{\it name}\bf$\{$ \it text \bf$\}$}
\tcon{\\REFSCON\\{\it name}\bf $\{$ \it text \bf $\}$}
and
\tc{\\refsend  .}
 
To use these commands to generate multiple references you invoke
them sequentially.
For example, suppose you wish the next three references to form
a single multiple reference.
Begin by selecting the word to which you wish to attach the
reference mark.
After the word to which you wish to attach the appropriate
reference mark, you type in the first reference
\referencecount=0
\REFS\first{This is the first reference of a series.}
\REFSCON\second{The papers just mentioned are unimaginative,
stupid, incorrect and besides I did it first.}
\REFSCON\third{I am running out of references.}
by typing \nextline
{\bf \\REFS\\{\it first}\bf $\{$ \it
This is the first reference of a series. \bf $\}$} \nextline
You then type the next reference using the command {\bf \\REFSCON}
as follows \nextline
{\bf \\REFSCON\\{\it second}\bf $\}\{$ \it
The papers just mentioned are unimaginative,
stupid, incorrect and besides I did it first.\bf $\}$} \nextline
In the same way you continue with {\bf \\REFSCON} to generate
all succeeding references.
Hence, to input the third reference you type \nextline
{\bf \\REFSCON\\{\it third}\bf $\{$ \it
I am running out of references. \bf $\}$ } \nextline
You finally cause PHYZZX to generate the reference mark by
typing\refsend
\tc{\\refsend}
after the closing brace of the last reference.
As you see, this set of macros has kept track of the numbers
of the references, filed the text for
each reference away and finally combined the number of the first
and last reference in the set into a single reference mark and
attached it to the word {\it typing}.
To see what has been filed away we type {\bf \\refout}
and obtain
 
\refout
 
If you wish to generate an automatically numbered multiple
reference but have no need to name the individual references
then we provide the commands {\bf \\refs} and {\bf \\refscon}.
The syntax of these commands are
\tc{\\refs$\{$ \it text \bf $\}$ }
and
\tc{\\refscon$\{$ \it text \bf $\}$ }
The command {\bf \\refs$\{$ \it text \bf $\}$} is equivalent
to {\bf \\REFS\\?$\{$ \it text \bf $\}$ }
and the command {\bf \\refscon$\{$ \it text \bf $\}$}
is equivalent to {\bf \\REFSCON\\?$\{$ \it text \bf $\}$}.
The fact that the name {\bf \\?} is assigned
to each reference in turn makes it less useful than in the command
{\bf \\ref} and so you would not tend to use this command unless
you are typing an already finalized manuscript.
 
\subsection{The Problem of Long References }
 
First, you we should observe that there is no problem combining
many citations in a single reference.
Obviously, this can be done by typing them in as the argument
of any one of the reference commands.
If, however, you wish to have a series of citations all appear
under the same number, but wish to have them appear on
individual lines all you have to do is follow each one by the
command {\bf \\nextline}.
What {\bf \\nextline} does is generate a neat break and starts
\TeX\ off printing the material which follows at the beginning of
a new line.
The important fact about {\bf \\nextline} is that it preserves
the indentation of the text established by the reference macro.
 
This brings us to the second point.
{\it What happens if you wish to have a reference which consists
of several paragraphs ?\/}
Here you have to be careful, since if you use the command {\bf \\par}
or leave a blank line (which amounts to the same thing)
you will spoil the indentation of the text material.
To avoid this a special macro exists called {\bf \\subpar}.
To get vertical space between text in a single reference
type the command {\bf \\subpar}
whenever you would ordinarily insert
the command {\bf \\par} or leave a blank line.
It will accomplish the same feat as {\bf \\par \\noindent}
but it will not mess up the formatting of the reference page.
 
Having discussed the way to properly generate long references, we
now come to the problems this will cause.
The fact is, \TeX\ has trouble writing long lines to
an external file.
Since, as far as \TeX\ is concerned the argument of any one of
the reference macros is just one long line, there will come the
time when \TeX\ will complain in a mysterious way.
If you are running interactively it will issue a horrible looking
PASCAL error message (sending the unforwarned into a case of
cardiac arrest) and then continue with its processing.
Since \TeX\ will resume processing after this frightening hiatus
you will promptly recover, shake your head and say {\it Ain't
computers peculiar?\/}.
You will also, in all probability, ignore the fact that it happened.
This will be a mistake.
If you look in {\bf referenc.texauxil} on your A disk, you will find
that \TeX\ has found one of the references is too long
and has chopped it off, replacing most of the text by
{\bf \\ETC}.
I presume that in general this will not be what you intended.
\nextline
\titlestyle{\twelvepoint \it Have no fear, PHYZZX is here !}\nextline
There is a control sequence which solves this problem; unfortunately,
it is not a really neat solution.
The solution is to go back into the reference and type
{\bf \\splitout} at various places in the text.
This command tells \TeX\ to begin sending a new line to the
file.
As I said, this is a solution but not an elegant one.
We are saddened that the elegant solution has escaped us and
hope that a \TeX pert out there will tell us a better way to proceed.
 
\subsection{Questions of Style}
 
Sometimes you will wish to attach a reference mark to a word
which is immediately followed by a comma.
This presents you with two choices neither of which produce
truly satisfactory text.
If you type \nextline
\ $\ldots $ {\it this is the place,}{\bf \\refend} \nextline
you get \nextline
$\ldots $ this is the place,\refend \nextline
and if you type  \nextline
$\ldots $ {\it this is the place}{\bf \\refend}, \nextline
you get
$\ldots $ this is the place\refend , \nextline
In the first case the reference mark is really attached to the
comma, causing an unsightly extra amount of space;
in the second case the reference mark separates the word from
the comma, which is even worse.
The way out of this predicament is to make use of Knuth's
command {\bf \\rlap}
If you type \nextline
$\ldots $ {\it this is the place}{\bf \\rlap},{\bf \\refend} \nextline
you get \nextline
$\ldots $ this is the place\rlap,\refend \nextline
which is much better.
Obviously the same trick applies to the macros
{\bf \\refsend}, {\bf \\refmark}, {\bf \\ref}, {\bf \\Ref} and
{\bf \\attach}.
 
Because of the way references work you always get a single
space after an attached reference.
Basically this means that if you attach the reference mark to
the last word in a sentence, the next sentence will start too
close.
There is a way out of this dilemma.
Type  \nextline
{\it the  end of the world}{\bf \\rlap}.{\bf \\refend\\ \quad}
The next\nextline
which will produce \nextline
the end of the world\rlap .\refend\   The next \nextline
The {\bf \\ \quad} forces more space between the sentences.
 
Finally, if you need a reference followed by a colon and want
to get rid of the extra space that the reference macro puts in
simply type {\bf \\refend\\unskip}.
The command {\bf \\unskip} is a Knuth construct which eats
the last extra space you entered.
(Actually, it eats the last bit of glue that
was inserted into the text, but that is a matter for \TeX perts.)
 
\subsection{Typing Journal Entries: A Convenient Macro }
 
Since many of the references which appear in a paper are
citations of articles appearing in various physics journals
we have a special macro to handle this problem.
The reason one uses a macro to do this is that \TeX perts
are expected to typeset such references with the journal name
in as slanted ({\bf \\sl}) font, the volume number in boldface
({\bf \\bf}) font and the remaining text in roman ({\bf \\rm}) font.
You can either remember to do all of this or you can use the
command {\bf \\journal}.
The syntax of this command is
\tc{\\journal{\it journal name}{\bf \&}{\it volume number}%
{\bf (}{\it year}\bf )}
This command is used inside any
one of the reference commands as follows:
if you want to obtain the same result as typing \nextline
{\bf \\ref$\{$ \it T.\~\ Banks and V.\~\ Kaplunovsky \bf \\sl
\it Nucl. Phys. \bf \~\
\\bf \it B211 \bf \\rm \it (1983) 529 \bf $\}$} \nextline
you need only type \nextline
{\bf \\ref$\{$ \it T.\~\ Banks and V.\~\ Kaplunovsky \bf
\\journal \it Nucl.Phys.\bf \& \it B211 (83) 529 $\}$}
This will produce a reference entry of the form \nextline
\refitem{1.} T.~Banks and V.~Kaplunovsky \journal Nucl.Phys. & B211 (83)
529
 
Note, the blanks before {\bf \\journal}, before and after the
character {\bf \&} and before and after the {\it (year)} are
optional.
If everything is working as it should they will have no effect
on the final result.
On the other hand, be careful about blanks within the parentheses;
if you put them in they will appear.
Thus, typing ( 83 ) produces a different result from typing (83).
The first will result in the journal year being typed as 19 83
and not 1983 which is, presumably, the desired result.
 
\section{Figures and Tables}
 
There are two other things which tend to appear at the end
of a paper and to which one refers in the text.
These are Figure Captions and Table Captions.
In general these things come up as you are typing
in some text and decide {\it Aha! This is a good place for a figure
(or table)}.
As with equations and references, it is convenient to be able
to generate a number for this figure(table), name it and file
away the text of the figure caption (or something which will remind
you what figure you wanted to put there) in a file called
{\bf figures.texauxil} (or {\bf tables.texauxil}) to be printed
at the end of the paper.
The commands which accomplish this feat are
\tc{\\FIG\\{\it name}\bf$\{$ \it text $\}$}
and
\tc{\\TABLE\\{\it name}\bf $\{$ \it text \bf $\}$}
As in all other variants of this naming convention,
{\bf \\name} will be the name of the figure (or table)
generated, and {\it text} is the material to be stored away
in a file on your A disk.
These commands work like the reference or equation commands
in that the numbering is automatic and
will always be correct no matter how you subsequently modify the
text.
The commands, analagous to {\bf \\refout}, which print the
list of figure or table captions are
\tc{\\figout}
and
\tc{\\tabout}
which should come as no big surprise.
 
There is a fundamental way in which the figure and table caption
macros differ from the reference macros; namely, they do not
automatically generate a reference mark.
This is because you normally want to say something like \nextline
$\ldots$ {\it as you can see from Fig. 7 } \nextline
or something like that.
The basic macros, i.e. {\bf \\FIG} or {\bf \\TABLE} permit
you to type this in as you please.
For example, one way to have \TeX\ generate the line above
is to type \nextline \figurecount=7
{$\ldots $ \it as you can see from \bf \\FIG\\?$\{$ \it text
\bf $\}$} Fig.{\bf \~\ \\?} \nextline
which will produce  \nextline
$\ldots $ as you can see in \FIG{\?}{this is the picture of the Mona
Lisa generated as a fractile} Fig.~\? \nextline
Obviously, using this form of the command (either for a figure or
a table) you have total control of what follows.
Moreover, for simplicity I chose to name the figure {\bf \\?}
since I only intended to refer to it this one time.
It is clear that I could have given it any name.
 
For those of you who are happy to use the command exactly in this
way, i.e. to name the figure {\bf \\?}, file away the caption
and then type either {\it Fig.\~\ \\?} or {\it fig.\~\ \\?}
there are two macros, named {\bf \\Fig} and {\bf \\fig}
respectively.
The syntax of these commands is somewhat simpler; namely,
\tc{\\Fig$\{$ \it text \bf $\}$}
and
\tc{\\fig$\{$ \it text \bf $\}$ }
They are the analogues of the set of reference macros which
automatically generate a reference mark whose name is {\bf \\?}
after filing away the text of the figure caption.
What they do is first execute the command \nextline
\tc{\\FIG\\?$\{$ \it text \bf $\}$}
and then follow this by either Fig.\~\ or fig.\~\ .
The analagous macro for tables is
\tc{\\Table$\{$ \it text \bf $\}$}
which performs the same task as typing
\tc{\\TABLE\\?$\{$ \it text \bf $\}$ \rm Table\bf \~\ \\?}
 
This completes our discussion of macros associated with {\it things
which come at the back}.
 
\chapter{FOOTNOTES: THINGS WHICH COME AT THE BOTTOM}
 
Everybody knows what a footnote is and you have already seen an
example of a footnote appearing on page~5.
Basically what a footnote macro has to do is
attach a footnote mark to a specified word and then
file away material to be put at the bottom of the page
(in ten point type).
The macro has to decide what to do if the footnote is too long,
or if many footnotes appear on the same page.
In addition, it has to decide what footnote mark to generate.
PHYZZX has two macros which carry out this feat.
 
The first macro, {\bf \\foot}, has the syntax
\tc{\\foot$\{$ \it text $\}$}
where the text of the footnote is to be inserted between the
braces.
When you invoke this command immediately following the word
to which you want to attach a footnote mark it does several
things.
First it generates the footnote mark and attaches it to the
preceding word.
If you are in the Nucl.Phys. format, this symbol will automatically
be chosen from the set of symbols $\star$, $\dagger$, $\ast$,
$\ddagger$, $\natural$, $\diamond$, $\bullet$ and $\nabla$.
The macro will continually cycle through this table, according
to a specified algorithm, in such a way that the same symbol
will not (except in truly extraordinary circumstances) appear twice
on a single page.
If you are in PHYSREV mode, then the footnote mark will be a
superscripted $\sharp$ sign followed by the current value of
{\bf \\number\\footsymbolcount}.
This is a truly ugly convention, however it is included only
to provide something for people who insist on numbering footnotes.
Actually, Phys.Rev. does not like footnotes and preferes this
material be included in with the references as endnotes.
 
Note, that as with references, the text of a footnote is
indented using the \TeX\ command {\bf \\hangindent},
hence to insert multi-paragraph footnotes one cannot use the {\bf \\par}
command but must use instead the {\bf \\subpar} command.
If you don't do this, but use {\bf \\par} (or equivalently insert a
blank line) then \TeX\ will, obligingly, turn off the {\bf \\hangindent}.
This will, of course, mess up the footnote considerably.
 
\subsection{Hints and Warnings}
 
Since footnotes use \TeX 's basic {\bf \\insert} command,
they are meant to be used in {\it unrestricted horizontal mode}.
In other words, you use them inside paragraphs, but outside
of {\bf \\hbox}, {\bf \\centerline} or similar commands.
If you don't understand the meaning of the phrase {\it unrestricted
horizontal mode} you should read about it in the \TeX book,
or in {\bf First Grade \TeX }.
This fact means that one has to be careful in attempting combine
certain other control sequences with the {\bf \\foot} command.
 
\pointbegin
Do not define references, figure captions, table captions, etc.,
inside the text of a footnote.
If you must put a reference mark inside a footnote use the command
{\bf \\REF} somewhere before you start the footnote and then
use {\bf \\refend} inside the text of the footnote.
 
\point
If you choose to invoke a footnote when you are in vertical mode
between paragraphs, then the footnote, complete with its footnote
mark, will be generated; however, since there is nothing to
attach this mark to, no superscripted footnote mark will appear.
Since the command will generate a footnote mark, the counter
{\bf \\footsymbolcount} will be advanced and so, insofar as PHYZZX
is concerned, the symbol is waiting around to be used.
Hence, if you wish to attach this symbol to a word at a later point
this can be accomplished by use of the subcommand {\bf \\footattach}.
All you have to do to use {\bf \\footattach} is type it immediately
following the word to which you wish to attach the footnote mark.
This command works just like {\bf \\attach} or {\bf \\refmark}
except that it attaches the current footnote mark and knows whether
to use Nucl.Phys. or Phys.Rev. format.
 
\point
We already noted that if you wish to attach a footnote
inside of a box (either horizonatal or vertical)
the way to do it is to use {\bf \\foot} after the previous paragraph
has ended, but before you make the box in question.
Then use the command {\bf \\footattach} inside the box.
What happens if you need to attach the footnote mark
to something inside a box which appears inside a paragraph?
In this case you can use the PLAIN command {\bf \\vadjust}
to accomplish this feat.
Simply type
\tc{\\vadjust$\{$ \it text \bf $\}$\\nobreak}
immediately before the box and then use {\bf \\footattach} inside
the box.
 
\subsection{Controlling Your Footnote Marks}
 
Once again, this section is for those who wish to go beyond
the mundane and use unusual symbols for their footnotes.
This can be done by using the PHYZZX command
\tc{\\footnote$\{$ \it symbol \bf $\}\{$ \it text \bf $\}$ }
which will generate a footnote using the {\it symbol} you have
specified as the footnote mark.
The symbol can be any math mode symbol, or any outr\'e thing
that you can think up.
The symbol does have to be in math mode, so if it is something
you made up instead of a math mode control sequence, be sure to
{\bf \\hbox} it and enclose it in \$ signs.
 
\chapter{ITEMIZED LISTS: POINTS, ITEMS AND OTHER STUFF}
 
You now have all of the necessary information to allow you
to use PHYZZX to format a paper for the printer:  you can
tell him to set up chapter, section and subsection headings;
number equations; format the reference, figure caption and
table caption page; format footnotes, keep track of how
many are on a page and carry them over to succeeding pages if
it is necessary.
From a stylistic point of view there is nothing more for you
to learn about papers.
Using the basic commands defined in PLAIN \TeX\ and those
PHYZZX macros which we have already discussed, you are now
capable of generating a paper of the correct style to be
the body of a SLAC preprint.
What we have not discussed to this point are things like macros for
title pages and macros which make typing special constructions
simpler than they would be in PLAIN.
 
In this section we will discuss a set of
macros which make the construction
of {\it itemized lists} particularly easy to achieve.
Itemized lists appear most often when one is outlining a paper
and trying to arrange the material in some systematic fashion.
This sort of outline shows up in memos and the introduction to a
paper.
Itemized lists also appear in the body of the text when one wants
to make a series of points and, at the same time, clearly separate them
from the format of the general body of the text.
 
Lists of this sort are conventionally set up as a series of indented
paragraphs preceded by some sort of highlighting symbol.
This symbol can be a number, letter, roman numberal or some math
mode symbol such as a dot, star, diamond, etc.
When used in writing outlines, etc., one indicates the major divisions of
the outline by indenting the text associated with
them some fixed amount and highlighting this text with a specific
type of symbol.
When itemizing the ideas which fall within each major division, one
usually indents the text somewhat more than one did for the major
divisions and highlights each of these sub-points with a symbol
which differs in type from those used to highlight the major points.
One then further subdivides each of these categories into smaller
steps and indicates this fact by once again increasing the amount of
indentation and once again changing the type of highlighting symbol used.
So on ad-infinitum $\ldots$
 
Obviously, at least for those of you who have read the \TeX book,
all of this can be done using the commands {\bf \\hangindent}
and {\bf \\hangafter}.
However, if one is creating long lists of points, subpoints,
subsubpoints, etc., then keeping track of the symbols and
appropriate levels of indentation can get to be a problem.
For this reason PHYZZX provides a series of macros to make this as simple
as possible.
As in the previous cases, we will begin by discussing the
fixed format versions of the macros, which are the ones which are easiest
to use, and go on to discuss the ones which allow you greater flexibility.
 
\section{Fixed Format Lists: Points, Subpoints, Subsubpoints}
 
\subsection{Points}
 
The macros {\bf \\point},{\bf \\subpoint} and {\bf \\subsubpoint}
exist to make it easy to deal with itemized
lists having up to three levels
of indentation.
The first level of indentation is the smallest and is generated by
typing the command {\bf \\point} followed by the text associated with that
point.
Note that unlike the reference or footnote macros,
the text associated with
a {\bf \\point} {\it does not} need to be enclosed in braces.
Points, etc. are constructed using the {\bf \\hangindent} command
and so \TeX\ accepts all of the text up to the next {\bf \\par} (or blank
line) and formats it as you desire.
For this reason, if a point is to consist of more than one paragraph
{\it do not use the {\bf \\par} command to generate the second paragraph}
but, instead, use the special command {\bf \\subpar}.
In addition to indenting the material to follow, the command
{\bf \\point} also generates a number for the point and attaches it
to the left of the first line.
You have seen examples of points in other parts of this writeup; go back
and look at them if my sentences are confusing.
Each time you type {\bf \\point}
PHYZZX generates a new paragraph, increases
the number of the last point by one and appends this to the left of the
first line of the new point.
Obviously, this works well until you finish with a given set of points
and then decide you want to make a new list of points at a later point
in the same paper.
Except in unusual circumstances you would like the first item on this
list to be labelled 1, and not start up from the number assigned to
the last point in the previous list.
To avoid this sort of calamity you use a special command to begin
a new set of points namely, the command {\bf \\pointbegin}.
(Clearly this choice of nomenclature is far
from sprightly and imaginative,
but it is easy to guess what the correct command is even if you
have forgotten it.)
 
As an example suppose you type \nextline
{\bf \\pointbegin} \nextline
This is the first point I wish to make.  \nextline
{\bf \\point} \nextline
This is the second point. \nextline
{\bf \\point} \nextline
I am not very imaginative, so this is the third point. \nextline
You then obtain
\pointbegin
This is the first point I wish to make.
\point
This is the second point.
\point
I am not very imaginative, so this is the third point.
 
\noindent
You then return to typing ordinary text by following the text of
the last point in your list with a {\bf \\par} or blank line.
 
\subsection{Subpoints and Subsubpoints}
 
The format of a subpoint is that it is indented further and
highlighted by lower case letters enclosed in parentheses.
The command for generating a subpoint is {\bf \\subpoint}
and, as with points, each time you type {\bf \\subpoint}
you automatically generate the next letter in the alphabet
as a highlight.
As with points, in order to start the numbering over again
you start each set of subpoints by typing
{\bf \\subpointbegin} instead of {\bf \\subpoint}.
For example, typing \nextline
{\bf \\pointbegin} \nextline
This is the first point I wish to make.  \nextline
{\bf \\subpointbegin} \nextline
This is the first subpoint. \nextline
{\bf \\subpoint} \nextline
This is the second subpoint \nextline
{\bf \\subpoint} \nextline
Etc. \nextline
{\bf \\point} \nextline
This is the second point. \nextline
will generate
\pointbegin
This is the first point I wish to make.
\subpointbegin
This is the first subpoint.
\subpoint
This is the second subpoint
\subpoint
Etc.
\point
This is the second point.
 
Subsubpoints are the last automatically provided subdivision
and are generated using the commands {\bf \\subsubpointbegin}
and {\bf \\subsubpoint}.
They are indented still further and highlighted by lower case
roman numerals enclosed in parentheses.
I leave it to you to generate you own examples of subsubpoints,
the syntax is completely similar to that of the previous examples.
 
The command {\bf \\spoint} is acceptable as an abbreviation
for {\bf \\subpoint}.
Abbreviations for the other commands are similar; i.e.,
\settabs 3 \columns
\+ {\bf \\spointbegin} & for &{\bf \\subpointbegin} \cr
\+ {\bf \\sspoint} & for & {\bf \\subsubpoint} \cr
and
\+ {\bf \\sspointbegin} & for & {\bf \\subsubpointbegin} \cr
 
\section{For Less Structure Consider Items}
 
There will come the time, especially for those of you who learn
to use \TeX\ to generate transparencies, when you want to be able
generate itemized lists, but you don't want the highlighting
to happen automatically.
Instead you might like to generate stuff with a {\bf \\bullet}
or an {\bf \\ast} as a highlight.
For those among you who are left brain dominated and
feel the need for a macro set which
takes care of the boring details of indentation, but allows
you to play fast and loose with the highlights,
PHYZZX provides the macros
\tc{\\item$\{$ \it symbol \bf $\}$}
\tc{\\subitem$\{$ \it symbol \bf $\}$}
and
\tc{\\subsubitem$\{$ \it symbol $\}$}
(The last two commands can be abbreviated as {\bf \\sitem} and
{\bf \\ssitem} respectively.)
 
\item\bullet
For example, this item was generated by typing {\bf \\item\\bullet}.
Note that I did not put {\bf \\bullet} in braces since it
is a single control sequence. If I had, however, it would have
done no harm.
Spaces and blank lines before {\bf \\item} are irrelevant,
however, since {\bf \\bullet} is a control sequence and eats
one space following it, you have to have at least one blank
after {\it symbol}.
Once again I caution you that if you put a blank line or {\bf \\par}
after {\bf \\item} and before the text, or inside a multiparagraph
{\bf \\item}, then you destroy the level of indentation.
{\it Remember, indentation only holds for a single paragraph in \TeX .}
 
\item\ast
As a second example consider this item which was generated by
typing {\bf \\item\\ast}
 
\item\dash
Or this, which was generated by typing {\bf \\item\\dash}.
 
At this point I have inserted a blank line in my text and have
caused the item to terminate and the text reverts to its ordinary
format.
 
\item\clubsuit
This is item {\bf \\item\\clubsuit}
 
\sitem\diamondsuit
And this is {\bf \\sitem\\diamondsuit}
 
\ssitem\dash
Finally, this is a subsubitem; \nextline
it was generated by typing
{\bf \\ssitem\\dash}.
 
\section{Having Your Cake and Eating It Too!}
 
Clearly, the {\bf \\item},{\bf \\sitem} and {\bf \\ssitem}
macros provide you with the ultimate in flexibility
in the choice of highlighting conventions.
With them alone you can choose your own format for numbered lists
and never have to accept the format imposed by {\bf \\point}, etc.
However, the total lack of structure of {\bf \\item}, etc.
has a drawback; namely, if you use it to define your points, subpoints
etc., you are responsible for keeping track of all of the numbering.
This is certainly not too
formidable a task, but it can get tedious. \nextline
\centerline{\it  Fortunately,  there is a middle ground.}
 
\subsection{Levels of Indentation}
 
If all that you want to do is change the levels of indentation
of points, subpoints and subsubpoints you only have to modify
the parameter {\bf \\itemsize}.
This parameter is a dimension stored away in \TeX 's memory
and items are indented {\bf 1.0\\itemsize}, subitems are indented
{\bf 1.75\\itemsize} and subsubitems are indented {\bf 2.5\\itemsize}.
The current value of {\bf \\itemsize} is 30pt (30 points);
however, you can change this by simply typing
\tc{\\itemsize = \it 40pt}
or whatever else strikes your fancy.
 
\subsection{Getting More Serious}
 
Let us suppose, although I cannot imagine that this could possibly
be the case, that you have more serious problems with points, subpoints
and subsubpoints.
Perhaps you would prefer to define your own listing macros
so that {\bf \\mypoint} generates a point whose highlight
is a capital letter followed by a period; {\bf \\myspoint}
generates a subpoint highlighted by a number square brackets;
and {\bf \\mysspoint} generates a subsubpoint highlighted
by a lowercase letter in parentheses.
You have two options, you can write your own macro set
or you can use the PHYZZX command {\bf \\newlist}.
 
The command {\bf \\newlist} allows you to define your own
listing macros which format things in a manner which is closer
to your heart's desire.
All you have to decide is what sort of delimiters you want
around the highlighting number and what you want the numbering
convention for that level of point to be.
Your available choices are the five defined when we discussed
changing chapterstyle; namely, {\bf \\Number},
{\bf Alphabetic}, {\bf \\alphabetic},
{\bf \\Roman} or {\bf \\roman}.
 
The syntax of the newlist command is as follows
\tc{\\newlist\\{\it name}= \it [left delim.][style]\& [right delim.] \&
[dimen]; }
(Note that the =, \& , and ; all count.)
As an example of its application note that the {\bf \\point}
command is defined by saying
\tc{\\newlist\\point=\\Number\&.\&1.0\\itemsize;}
This line tells PHYZZX to define a new command called
{\bf \\point} and to have it generate a highlighting symbol
which consists of no left delimiter, followed by a number,
followed by a right delimiter which is a period and the indentation
of a point is to be {\bf 1.0\\itemsize}.
Similarly, subpoints are defined to be
\tc{\\newlist\\subpoint=(\\alphabetic\&)\&1.75\\itemsize;}
and subsubpoints are defined by saying
\tc{\\newlist\\subsubpoint=(\\roman\&)\&2.5\\itemsize;}
The abbreviations for {\bf \\subpoint} and {\bf \\subsubpoint}
are obtained by following their definition with the
statements
\tc{\\let\\spoint=\\subpoint}
\tcon{\\let\\sspoint=\\subsubpoint}
Note, if you have chosen to redefine {\bf \\subpoint}
and {\bf \\subsubpoint} using newlist, the commands {\bf \\spoint}
and {\bf \\sspoint} will {\it not} be redefined unless you follow
your newlist instructions with the two lines printed above.
 
To define the new set of listing macros mentioned earlier you would type
\tc{\\newlist\\mypoint=\\Alphabetic\&.\&1.0\\itemsize;}
\tcon{\\newlist\\myspoint=[\\number \& ]\& 1.75\\itemsize;}
and
\tc{\\newlist\\mysspoint=(\\alphabetic\& )\& \\2.5\\itemsize;}
Note, while there are only five styles available for numbering
things, delimiters are limited only by your imagination.
 
\chapter{MISCELLANEOUS STUFF ABOUT PAPERS}
 
\section{Page Numbers}
 
Page numbering is a totally automatic procedure
and, in general, requires none of your attention.
Normally, if you are not doing anything funny PHYZZX will
produce a document whose pages are numbered consecutively
starting from 1.
In general the first page you get will be numbered, unless
you have told PHYZZX not to do so.
The macros {\bf \\FRONTPAGE}, {\bf \\MEMO}, {\bf \\letter}
and {\bf \\titlepage} do issue such a command, and when
invoked produce a document where all pages but the
first page are numbered consecutively.
If you type {\bf \\FRONTPAGE} then PHYZZX will complete the previous
page (if there is any), set the current value of the page number to
1 and then tells \TeX\ not to number this page.
Visible numbers appear at the bottom of all the pages which follow
and the first visible number is 2.
The command {\bf \\Frontpage} is a synonym for {\bf \\FRONTPAGE}.
The {\bf \\letter} and {\bf \\MEMO} macros, which
will be discussed later,
and the {\bf \\titlepage} macro, which is invoked when you are about
to type the title page of your latest magnum opus, all suppress
the printing of the pagenumber at the bottom of the first page.
 
If you wish to start a document in the middle and set the pagenumber
all you have to do is reset the counter called, of all things,
{\bf \\pagenumber} by typing
\tc{\\pagenumber= \it number}
This will make the first page \TeX\ prints have this number.
To make sure that the printing of this number is not suppressed
you should also type {\bf \\frontpagefalse}.
If you wish to have PHYZZX number the pages using roman numerals
you can accomplish this by saying {\bf \\pagenumber=-1}
(or {\bf \\pagenumber=-n} if you wish to start with the roman
numeral equivalent to the number n).
 
\item\dash
If you wish no pagenumbers type {\bf \\nopagenumbers}
(be careful, its not easy to make them come back afterwards).
\item\star
If you want to suppress the page number on a particular page you
can type {\bf \\frontpagetrue}, which will make PHYZZX
think that this is the front page.
You'll sometimes have to play to make this happen where you want.
 
\section{Spacing}
 
We have already talked about changing font sizes and selecting
spacing, and have pointed out that three families of fonts are
available.
These are fonts which are fourteen points high, twelve points
high and tenpoints high.
The twelvepoint font is the font PHYZZX uses for normal text
because it looks best when reduced.
The fourteenpoint fonts are used for chapter titles, etc., and
the tenpoint font sets, which are kind of small when reduced,
are generally reserved for footnotes.
To change font size at will you type either
{\bf \\tenpoint}, or {\bf \\twelvepoint}, or
{\bf \\fourteenpoint}.
To change spacing conventions you use the commands
{\bf \\singlespace}, or {\bf \\normalspace}
or {\bf \\doublespace}.
Note that all of these commands can be used inside the paper
to temporarily change what is going on;
however, you should only invoke the
commands which change spacing when you are between paragraphs.
If you violate this rule, eventually, you
will be sorry.
 
\section{Commands Which Break Lines and Pages}
 
\TeX\ has its own way of breaking lines and pages and you can learn
about them by reading the \TeX book.
However, we have added three commands which are convenient.
The first command {\bf \\nextline} allows you to generate and
incomplete line.
For example, typing {\it This is the way the world ends \bf \\nextline}
produces \nextline
This is the way the world ends \nextline
Notice that \TeX\ has not tried to space the words out to fill
the line the way it would have if you had typed {\bf \\break}.
The command {\bf \\nextline} is essentially the same as typing
{\bf \\hfil\\break}; it differs slightly in that it also
does some things about glue, but you don't have to know about that.
 
The command which forces \TeX\ to break the page at will
is {\bf \\endpage}.
Typing this command forces \TeX\ to start a new page
and at the same time it insures that even if the previous page
is not completely full of text the material will be spaced correctly.
 
The command with which you finish a paper, memo, letter, etc.,
is {\bf \\bye}.
This command tells \TeX\ to complete the last page, print it and
then turn itself off, returning you to CMS.
 
\section{Some Remarks About Penalties}
 
There are a few commands, which belong to PLAIN and not PHYZZX
which you should know about.
The basic command which allows you to tell \TeX\ that you
would advise it that this is a good or bad place to break
a page or line of text is {\bf \\penalty}.
Penalties can be either positive or negative.
If a penalty is positive it tells \TeX\ that this is not a good
place to put in a break.
The bigger the penalty is, the worse \TeX\ thinks it is to cause
a break at this point.
The biggest allowable penalty is {\bf \\penalty 10000}.
If you type {\bf \\penalty 10000} at a specific point in the text
than \TeX , as the printer, will assume that no matter what his
judgement tells him, you insist that no break can occur at this
point.
\TeX\ defines a control sequence {\bf \\nobreak} which equivalent
to typing {\bf \\penalty 10000}.
If the penalty is negative, then \TeX\ is advised that you
believe this point to be a good place to cause a break.
The more negative the penalty, the better you think this place is.
If the penalty is negative and greater than
-10000, then \TeX\ will
use its own judgement to balance off your suggestion against its
own esthetic criteria.
If the penalty is -10000 (or less), then you are telling \TeX\
that your judgement must carry the day.
The abbreviation of {\bf \\penalty -10000} is {\bf \\break}.
 
Note that using the
same commands inside paragraphs and between paragraphs
tell \TeX\ to do different things.
Inside of a paragraph {\bf \\break} tells \TeX\ to break the
current line at this point, between paragraphs it tells \TeX\
to break the page.
If you wish to force \TeX\ to break the page inside a paragraph,
without terminating the paragraph, you have to type
\tc{\\vadjust\\break}
 
 
\section{The Titlepage}
 
We have now finished with our discussion of macros which PHYZZX
defines for simplifying the formatting of the body of a paper.
To complete our discussion of the paper generating capabilities
of PHYZZX we now have to turn to the question of generating
the title page.
A SLAC title page has several parts.
\pointbegin
First, in the upper right hand corner of the title page
one has the publication number, date of submission and
a line telling whether this paper is to be distributed as
T, E or T/E .
This chunk of text has to be set up as a block with the
appropriate typeface chosen for each line and then the
entire block is right adjusted.
This block is referred to as the pub-block
\point
Next comes the title of the paper, which is set in fourteen point
type and this is followed by the list of authors and the
institutions they come from.
\point
After the title and author list you have a choice.
If you have a short abstract it is included at this point
and printed on the title page.
If, however, the abstract is too long, it will not fit
on the title page.
In this event you skip it and put it on the next page of the paper.
\point
After the abstract, or after the title and author list if the abstract
is too long, we have a line which tells the journal to which the
preprint has been submitted.
\point
The next line ends the main body of the title page.
After this line the remaining material, which are contract
acknowledgements, etc., are put at the bottom page in footnote format.
 
As you can see from this discussion the problem of formatting
the title page can get to be quite difficult if we don't have
special macros to help out.
For this reason a special set of macros for formatting title pages
has been included in PHYZZX.
 
\subsection{The Publication Block or Pub-block}
 
The first commands which you use relate to setting up the
block of type which gives the date, publication number, etc.
If you do not want such a block, you type
\tc{\\nopubblock}
If, as will usually be the case you want a pub-block, then
you have to specify what goes into it.
To specify the publication number you type
\tc{\\pubnum$\{$\it number \bf$\}$}
This causes PHYZZX to put the quantity {\bf \\pubnum} into
the publication number.
When you start the quantity {\bf \\pubnum} is {\bf 0000}.
 
The next item which appears in the macro is the date.
If you do nothing, then each time you run \TeX\ to produce a new
copy of the file it will put the current date in this place.
If you wish to set the date to printed by yourself, then you type
\tc{ \\date = $\{$ \it month day, year \bf $\}$ }
Note the braces around the entry because they have to be there.
 
Finally, the last thing that has to specified for the pub-block
is the pubtype, which is either T, E, or T/E.
To specify this quantity you type
\tc{\\pubtype=$\{$ \it publication type \bf $\}$}
 
\subsection{Specifying the Titlepage}
 
The next macro which has to be invoked is
\tc{\\titlepage}
This is a single control sequence which you type in just before the
titlepage. This command must follow the setting of the
{\bf \\pubnum}, {\bf \\date} and {\bf \\pubtype}
or you will only get the default values for these quantities.
What this macro does is tell \TeX\ that this is the titlepage of the
document and it should not be numbered.
 
 
\subsection{Typesetting the Title}
 
The next item to be typed is the title of the paper.
Since this is set in different size type and requires a certain
amount of spacing above and below the text, you should use the
macro {\bf \\title}.
The syntax of this command is
\tc{\\title$\{$ \it title \bf $\}$}
You are now ready to type in the name and institution of the author (or
authors) of the paper.
 
\subsection{Getting the Author(s) Right}
 
If there is a single author you type
\tc{\\author$\{$ \it author's name \bf $\}$}
This is, of course to be followed by his address.
PHYZZX will set the name in upper and lower case capital letters
and center it on the page.
Then, if you use the macro {\bf \\address} PHYZZX will typeset the
address in italics and center it
directly below the author's name.
The syntax of this macro is
\tc{\\address$\{$ \it address \bf $\}$}
In general PHYZZX will let \TeX\ decide how to break the address
into several lines if it is too long.
If you wish to force these breaks use the command {\bf \\break}.
Note, this is a place where you do not want to use the command
{\bf \\nextline} or you will force the address to come out
without having been properly centered.
For those lucky persons who live at SLAC, there is a special macro
to save them typing.
This macro has the name {\bf \\SLAC} and if you wish to tell PHYZZX
that your address is SLAC all you have to type
\tc{\\SLAC}
If the author of the paper is a visitor, or is here on detached service,
then you might want to give two addresses.
To have \TeX\ print the second address below the first with the
word {\it and} in between, all you have to do is type
\tc{\\andaddress$\{$ \it second address \bf $\}$}
 
If the paper has more than one author you have two options.
If the number of authors is small and they come from different
institutions, then you use the macro {\bf \\andauthor}
whose syntax is
\tc{\\andauthor$\{$ \it author's name \bf $\}$}
This does what the {\bf \\author} command does but it also
precedes this name with a line which has the word {\it and}
centered above the author's name.
This command is then to be followed by {\bf \\address} in order to
give the address of the second author.
This can go on as long as you like.
 
All of this works well for theorists, however it does not work
well for experimental papers.
Experimantal collaborations tend to involve many authors from
several different institutions.
All we can do in this situation is to type the command
{\bf \\authors} and then follow this with a list of authors
and institutions.
All this command does for you is put the correct amount of
space between the list of authors and the material preceding it.
 
\subsection{Setting up the Abstract}
 
At this point you have to decide whether or not you want to
include the abstract on the titlepage.
If you wish to do so this is the time to type
{\bf \\abstract}.
This will cause \TeX\ to typeset the word ABSTRACT in the center
of the next line of text, skip the appropriate amount of space
and set you up in a new paragraph.
The next thing you do is type in the body of the abstract.
If you don't put the abstract on the titlepage then you
carry out this sequence of commands after you have finished the
titlepage with the command {\bf \\endpage}.
After you type in the abstract on the second page you should force
\TeX\ to print this as a separate page by once again typing
{\bf \\endpage}.
This will produce an abstract on its own page with white space
above and below the text.
 
If you are in the situation of having an abstract which is too
long for the title page but too short to fill the entire
second page you will get ugly output if you type it in
and follow it with the command {\bf \\endpage}.
\TeX\ will simply shove everything to the top of the
page because {\bf \\endpage} is the same as {\bf \\vfil\\break}.
The way to force \TeX\ to center the title and material is to type
\tc{\\vfil}
\tcon{\\abstract}
\tcon{\it text of abstract}
\tcon{\\endpage}
 
\subsection{Where's The Paper Going?}
 
In order to specify the journal to which you have submitted the paper
you type
\tc{\\submit$\{$ \it journal \bf $\}$}
For example, if it is going to Phys.Rev. D you would type
\tc{\\submit$\{$ \it Physical Review \bf \\bf \it D \bf $\}$}
which will produce the line \nextline
\centerline{ Submitted to Physical Review \bf D}
 
\subsection{Acknowledgements}
 
It is customary to acknowledge the support of various grants or
contracts somewhere on the titlepage.
Generally this is done in the form of a footnote.
The easiest way to get \TeX\ to typeset such acknowledgements is to
use the macro {\bf \\foot}.
You insert this footnote just after the last word of the title
or author's name, depending upon the situation, and then continue
setting the title page.
The {\bf \\title}, {\bf \\author} and {\bf \\address} macros
have been written in such a way that the {\bf \\foot} command
can be used with these macros without any trouble.
If you fool around with the title page and put things inside boxes
using the PLAIN \TeX\ commands {\bf \\line} or {\bf \\centerline}
this is not true.
In this case the text will be put inside a box in restricted
horizontal mode and you must use the commands {\bf \\footnote}
and {\bf \\footmark} as explained in our discussion of footnotes.
 
For theory group users there is a special macro which generates
the acknowledgement to the Department of Energy.
the command is {\bf \\doeack}.
To generate this acknowledgement you simply type
{\bf \\doeack} immediately after the last word in the title.
If other groups want to have their own {\bf \\doeack} macro
they need generate a file called MYPHYX TEX
and make sure it contains the lines  \nextline
{\bf \\def\\doeack$\{$\\foot$\{$ \rm Work supported by the Department of
Energy, contract \bf \$\\caps \rm DE-$\ldots$ \bf \$ $\}\}$ }
 
\subsection{Finishing the Title Page}
 
Close the title page with command {\bf \\endpage}.
If you don't do this \TeX\ will make some stupid decision about
adding extra material to this page.
You won't be happy with the results.
 
\section{A Sample Titlepage}
 
Let us conclude this section by including a sample title page.
If you type \nextline
\newcount\lastpage \lastpage=\pagenumber

\chapter{MEMOS}
 
We have now finished discussing all of the macros which have to
do with the formatting of papers.
Now as promised we will turn to a discussion of the two other
formats which PHYZZX supports.
The first format is that of a SLAC memorandum.
The second format is that of a letter.
 
A memorandum, as we have defined it, is a document meant for internal
distribution, addressed to a specific group of people and
designed to transmit information on a specific subject.
This sort of document tends to have a heading which identifies it
as a memorandum, gives the date, says to whom the memorandum is
being sent, from whom the memorandum comes and briefly summarizes
the topic being discussed.
This heading is then separated from the body of the memorandum
by some sort of ruled line and then one types in the text of
the memorandum.
 
To type a memorandum you begin by typing the formatting instruction
\tc{\\MEMO}
which tells PHYZZX the document to follow is a memorandum.
It also forces the document to be single spaced and generates
the heading which identifies the document as a SLAC memo
and gives the date at which the file was processed; \ie , the current
date.
If you wish to type a heading which has the date of your choice
then use the command {\bf \\memodate} instead of {\bf \\MEMO}.
The syntax of this command is
\tc{\\memodate$\{$ \it date of your choice \bf $\}$}
 
Now you have to generate the remainder of the heading; i.e.,
the to, from and topic (or subject) entries.
The macros which do this are
\tc{\\to \rm , \bf \\from \rm , and \bf \\topic \rm or \bf \\subject }
The commands {\bf \\to}, {\bf \\from} and {\bf \\topic} or
{\bf \\subject} work like points or items.
Hence, they do not need braces.
 
Finally, after typing in these commands followed by the relevant
text you need to generate a line to separate the heading from the
body of the memorandum.
This is done with the command {\bf \\rule}.
Having done this you are now ready to type in the text of the memorandum.
 
Note, all of the itemized list macros which we have discussed
in earlier sections work in the MEMO format too.
Hence, you can use them with impunity.
The same is true for footnotes, etc.
 
Finally, when you complete the memo, if you wish to indicate to whom
copies are to be sent you type
\tc{\\copies}
This command works like {\bf \\point} or {\bf \\item}
and so you would type
\tc{\\copies}
Mr. A. {\bf \\nextline} \nextline
Mr. B. {\bf \\nextline} \nextline
etc. \nextline
in order to get what you want
 
Don't be surprised when you generate multipage memoranda.
The way pages are numbered is going to be different from the
numbering of papers.
For a memorandum all but the first page are numbered with the numbers
appearing at the top of the page.
 
A sample memorandum is generated as follows; \nextline
 
\vbox{\tc{\\MEMO}
\tc{\\to}
Whom it may concern
\tc{\\from}
Marvin Weinstein
\tc{\\subject}
Generating memos without tears.
\tc{\\rule}
{\it
Look how easy it is to generate a sample memo.
Even a baby can type something like this.
If you use this macro to type your memos people will probably
take what you have to say more seriously.
(They shouldn't but they will!)
You can even type points, for example: \nextline
{\bf \\pointbegin} \nextline
Any fool would recognize that if we proceed in this way we can only
wind up with a disaster. \nextline
{\bf \\point} \nextline

to take a Hawaiian vacation.  They're just a bunch of old stick in the
muds. }
\tc{\\copies}
{\it Burton Richter \bf \\nextline} \nextline
{\it Richard Taylor }

Which generates something which looks like this}

\chapter{TYPING LETTERS AUTOMATICALLY}
 
In addition to typing papers and memos PHYZZX supports a format
for typing letters.
To choose this format all you need to type the command
\tc{\\letters}
immediately following
\tc{\\input phyzzx}
This command will cause PHYZZX to switch over to a different page
size, 8 inches long by 6.5 inches wide (this is a little
wider than a preprint) and it automatically changes the linespacing
to singlespace.
In addition, the same command tells PHYZZX to put a SLAC letterhead
at the top of the first page, and to change the way in which pages are
are numbered.
 
Having switched over to this mode the very next thing you need to do
is type in the date, followed by the name and address
of the person to whom the letter is being sent.
Getting the alignment of these various elements just right
takes some doing and so we have a macro to do the job.
The name of this macro is
\tc{\\letter}
Do not confuse this command with the initialization
command {\bf \\letters}.
Both statements must appear in your file and the command {\bf \\letters}
must come first.
I apologize for this construction but it is a leftover from
previous incarnations of PHYZZX.
Since we wanted this version of PHYZZX to be upward compatible we didn't
change it.
What the command {\bf \\letters} does is to tell PHYZZX that the
text to follow is to be set in {\bf \\letterstyle} and then
it makes PHYZZX print {\bf STANFORD UNIVERSITY} across the top of the
first page.
The command {\bf \\letter} tells PHYZZX that this is the first page
of a letter, prints the rest of the SLAC letterhead,
suppresses the printing of the pagenumber at the
bottom of this page and then allows you to type in the
name and address of the person to whom the letter is being sent.
The syntax of this command is
\tc{\\letter$\{$ \vtop{\hbox{\it Name \bf \\cr}
                       \hbox{\it first line of address \bf \\cr}
                       \hbox{$\ldots$  \\cr}
                       \hbox{\it last line of address \bf \\cr $\}$}}}
Note that any of the {\bf \\cr}'s can be replaced by the command
\tc{\\cropen$\{$ \it extra space \bf $\}$}
which will cause PHYZZX to leave the extra amount of space requested
between the lines; or you can replace the {\bf \\cr} by {\bf \\crr}
if what you want is 10 points of extra space.
 
The reason for typing the commands {\bf \\letters} and {\bf \\letter}
separately is that {\bf \\letters} initializes the format for typing
a letter and then {\bf \\letter} allows you to start several new letters
in a single file.
So long as you begin each letter with the {\bf \\letter} macro
each letter will start on a new page, and the letters will not know
about one another.
 
As with the titlepage macro, PHYZZX assumes that the date which is
to appear above the name and address is the current date.
If, however, you wish to fix the date appearing on the letter you
can do so by typing
\tc{\\date$\{$ \it your date \bf $\}$}
The {\bf \\date} macro will then make {\it your date} appear on all
of the letters in this file.
 
Once you have generated the letterhead, date and filled in the name
and address of the person to whom the letter is being sent,
you are ready to type in the body of the letter.
This is to be done in the same manner as for a paper or memo,
and all of the itemized list, etc., macros will work in this format
too.
 
\subsection{Typing the Salutation}
 
Finally, having typed in the body of the letter we come to the
problem of generating the signature.
Once again, since placing this upon the space and leaving the
correct space between the {\it Very truly yours,\/} and
the typed version of your name can get to be hairy, we provide the
macro {\bf \\signed}.
The syntax of this command is
\tc{\\signed$\{$
\vtop{\hbox{ \it Very truly yours (or whatever) {\bf \\cr}}
      \hbox{ \it Your name \bf \\cr $\}$ }}}
If copies of the letter are to go to several people you type this
at the bottom of the letter using the {\bf \\copies} command
discussed in the section on memos.
 
You finish a letter with the command {\bf \\endletter}.
This command insures that if there are several letters in the same
file each one will be processed independently.

\section{Multiple Letters}
 
Very often you wish to send the same letter to many different
people; hence, the text of each letter is the same but the
salutations will be different.
There are two ways to go about generating such a series of letters.
The only difference between them is that the first is somewhat
more conservative of computer time, but it can only be used for
relatively short letters; the second is a bit more demanding of
computer time, but it doen't care how long the letter is.
By a short letter I mean one which is no more than
one or two pages in length.
 
\subsection{Short Letters}
 
To type in short letters you begin by typing
\tc{\\letters\\multiletter}
This command is to be followed by the text of your letter.
What {\bf \\multiletter} does is tell PHYZZX to file away the
material to follow in the depths of its memory, to be used later.
You let PHYZZX know to stop stuffing stuff away by typing
\tc{\\letterend}
when you have finished.
Having now saved the body of the letter for future use you
generate your letters by typing
\tc{\\letter$\{$ \it Addressee  \bf $\}$}
followed by
\tc{\it Dear Mr. Soandso \bf \\par}
followed by the commands
\tc{\\lettertext\\endletter}
As you will have guessed the command {\bf \\lettertext}
is the name PHYZZX has assigned to the body of the
letter.
 
\subsection{For Longer Letters}
 
The second method for generating many letters is slightly more wasteful
of computer time, but to my mind it is simpler to use.
I reccommend it over the command {\bf \\multiletter} and
have included a brief discussion of the previous case only
to keep the macro set upward compatible.
Do us both a favor and forget I mentioned it.
 
This method takes a little longer because it requires \TeX\ to input the
same file many times.
It is simpler because it requires no change in syntax from
the format used for a single letter.
To use this method you create a file YOUR FILE A (the filetype
doesn't have to be TEX here),
which contains the body of your letter, including your signature.
You then create a driver file (filename TEX A) of the form
\tc{\\input phyzzx}
\tcon{\\letters}
\tcon{\it optional \quad \bf \\date$\{$ \it your date \bf $\}$}
\tcon{\\letter$\{$ \it Addressee \bf $\}$}
\tcon{\it Dear $\ldots$ \bf \\par}
\tcon{\\input your.file}
\tcon{\\endletter}
\tcon{\it $\ldots$}
\tcon{\\letter$\{$ \it Addressee \bf $\}$}
\tcon{\it Dear $\ldots$ \bf \\par}
\tcon{\\input your.file}
\tcon{\\endletter}
\tcon{\\end}
Note, the period between the filename and filetype is crucial.
What is being done in this method is that we are using \TeX 's
ability to input an external file as often as you wish.
This technique has the added advantage that you can even have the
letters vary somewhat.
To perform this trick you use the {\bf \\def} command.
To begin you use the names of some undefined control sequences in
the file YOUR FILE A, and then redefine these sequences
in the main driver file after each {\bf \\endletter} and before
the start of the next letter.
 
 
\chapter{MISCELLANEOUS MACROS WHICH PHYZZX DEFINES}
 
We have now finished our discussion of all of the macros which
pertain to the formatting of special documents.
This section simply lists some special macros which we have
included in PHYZZX simply because they simplify the task of
typing things which occur frequently.
 
The commands will be listed giving the syntax of each command and
an example of what it does.
 
\pointbegin
\tc{\\ie \quad \rm generates  \ie}
\point
\tc{\\eg \quad \rm generates \eg}
\point
\tc{\\dash \quad \rm generates \dash}
\point
\tc{\\\\ \quad \rm generates \\}
 
In math mode we have the following useful commands
 
\point
\tc{\\coeff$\{$ \it a \bf $\}\{$ \it b \bf $\}$ \quad \rm generates}
$$ \coeff{a}{b} $$
 
\endpage
 
 
\point
\tc{\\partder$\{$ \it f(x)
\bf $\}\{$ \it x \bf $\}$ \quad \rm generates}
$$ \partder{f(x)}{x} $$
\point
\tc{\\bra$\{$ \it \\Psi \bf $\}$ \quad \rm generates }
$$ \bra{\Psi} $$
\point
\tc{\\ket$\{$ \it phi \bf $\}$ \quad \rm generates }
$$ \ket{\phi} $$
\point
\tc{\\VEV$\{$ \it H \bf $\}$ \quad \rm generates }
$$ \VEV{H} $$
\point
\tc{\\Tr$\{$ \it G \bf $\}$ \quad \rm generates }
$$ \Tr{G} $$
 
\endpage
 
\point
\tc{\\int \rm generates }
$$ \int $$
\point
\tc{\\prop \rm generates  $\prop $}
\point
\tc{\\lsim \rm generates $\lsim $}
\point
\tc{\\gsim \rm generates $\gsim $ }
 
\chapter{GOODBYE}
 
This completes the basic writeup of the capabilities of PHYZZX.
As I indicated in the introduction, this is not the final version of
the macro set, but is in fact the last but one version that I
will have something to do with.
The final version will appear one of these days and will include
in the body of the FMT file several macros for creating wrap around
figure inserts and simple tables.
The macros already exist but
have not yet been collected together and finalized in format.
In addition, it will probably include a label making capability
to generate mailing labels for letters.
Don't hold your breath for this version, however, first I have
to get over having typed this documentation.
 
\section{Using Your MYPHYX File}
 
I promised you a short discussion of tailoring PHYZZX
into your own inimitable macro package.
The simplest way to do this is to have a complicated
file called MYPHYX TEX on your A disk.
If there are a few features of PHYZZX which do almost what you
want, but not quite, you can
look at the file PHYZZX TEX.
By reading Knuth and studying this file you will see how
everything PHYZZX does is made to happen.
The way to change something is to steal the relevant definition
from this file and copy it to your MYPHYX file.
Then, make the changes which you wish to make.
Since PHYZZX inputs this file after it makes its own
definitions, you desires will override the PHYZZX definitions.
