-\level1{Introduction}
-This set of macros was written as part of \HPTEX, Hewlett-Packard's software
-package designed to facilitate the use of \TeX\ on the HP Series 200 Desktop
-Computers.  The \HPTEX\ program can be run on either an SRM based, or a
-stand-alone (LIF) system, and requires 1.25 Mbytes main memory and a minimum
-of 15 Mbytes mass storage.  It uses an HP 2688A Laser Printer.
-
-The HP2688A is a page printer which uses scanned electrophotography technology
-to print computer output on single sheet paper.  The 300 dots per inch
-resolution, high contrast and speed, plus sophisticated character printing,
-allow a high degree of application flexibility.  Unique features include
-90\degrees\ rotation of page print, multiple pages of data output per printed
-sheet, and a graphics option.  The print rate is approximately 12 pages per
-minute.
-
-The \HPTEX\ macro package  is designed to supplement \TeX\ by providing macros
-for formating documents and for controlling the HP2688A.  The user of \HPTEX\
-can use any of the \TeX\ commands as well as the \HPTEX\ macro commands.
-
-While the formating macros include macros for headings and footings,
-paragraph style, lists, lines, boxes, paragraph headings, multiple columns,
-tables, and table of contents, they are not meant to be a complete system.
-They are intended to enable the user to get
-started, and to provide useful macros that can be modified and used as
-examples by the user for the creation
-of a customized macro package.
-
-A second release of \HPTEX\ is planned that will include graphics capability.
-
-\vfil
-On \indx{syntax}
-lines, when curly braces ``\[$\ldots$\]'' are shown, they are required in the
-source file, text between
-angle brackets ``\lb$\ldots$\rb'' identifies a parameter variable,
-and the character ``\spacechar '' represents a required space.
-\vfil\eject

-\level1{ Document Formatting Macros}
-The following HP \TeX\ commands control the basic style and formatting
-of a document:
-
-\level2{Page Layout}
-The HP \TeX\ defaults for \indx{page layout} are the same as they are in
-the \TeX\ program.  That is,
-all margins are set to approximately
-one inch from the edges. (Plain \TeX\ sets {\tt \+vsize=8.9in} and
-{\tt \+hsize=6.5in}.) \indx{Headings and footings} are printed {\bo outside}
-those margins.
-
-The following macros affect the running head and the footing of
-each page. The heading and footing lists are expanded during the
-output routine so the \TeX\ commands \indx{{\tentt\bs firstmark}},
-\indx{{\tentt\bs topmark}} and
-\indx{{\tentt\bs botmark}} are compatible here.
-
-\need.5in\bigskip\relax{{\tentt \+centerheading}}\[\hor\]\lbreak
-      \relax{{\tentt \+leftheading}}\[\hor\]\lbreak
-      \relax{{\tentt \+rightheading}}\[\hor\]\lbreak
-      \relax{{\tentt \+outsideheading}}\[\hor\]\lbreak
-      \relax{{\tentt \+insideheading}}\[\hor\]\lbreak
-These macros accept text which is to be placed at the top of every page.
-The first three macros place the argument in the center, left, or right
-of the page respectively.
-{\tt\bs outsideheading} and {\tt\bs insideheading},
-if specified, override the left and right headings. On odd pages, the
-inside heading will appear on the left, outside on the right.  Even
-pages are the opposite. (This feature is helpful when the output is
-to be used as two-sided copy.)
-
-
-\need.5in\bigskip\relax{{\tentt \+centerfooting}}\[\hor\]\lbreak
-      \relax{{\tentt \+leftfooting}}\[\hor\]\lbreak
-      \relax{{\tentt \+rightfooting}}\[\hor\]\lbreak
-      \relax{{\tentt \+outsidefooting}}\[\hor\]\lbreak
-      \relax{{\tentt \+insidefooting}}\[\hor\]\lbreak
-These are like the above commands, only they are for footings at the bottom
-of each page. For example, if page numbers
-are desired in the left side of the bottom of each page, type:
-{\tt\bs leftfooting\[\indx{\bs folio\]}}
-
-{\tt\bs outsidefooting} and {\tt\bs insidefooting} will
-produce similar results as {\tt\bs outsideheading} and
-{\tt\bs insideheading} (see above). The default in HP \TeX\ is
-{\tt \+centerfooting\[\+folio\]}. This produces page numbers at
-the center of the bottom of each page.
-
-\need.5in\bigskip\relax{{\tentt \+noheading}}\lbreak
-      \relax{{\tentt \+nofooting}}\lbreak
-These macros turn off headings or footings for the current and all
-successive pages until the {\tt\bs resumefooting} or
-{\tt\bs resumeheading} command is used.
-
-\need.5in\bigskip\relax{{\tentt \+suspendheading}}\int\lbreak
-      \relax{{\tentt \+suspendfooting}}\int\lbreak
-These macros suspend headings or footings for the specified number of
-pages or until the use of a {\tt\bs resumeheading} or {\tt\bs resumefooting}.
-
-\need.5in\bigskip\relax{{\tentt \+resumeheading}}\lbreak
-      \relax{{\tentt \+resumefooting}}\lbreak
-These macros undo the effects of the {\tt\bs suspendheading},
-{\tt\bs noheading}, {\tt\bs suspendfooting} and
-{\tt\bs nofooting} macros above.
-
-\break
-\level2{Paging}
-
-\cmd{\indx{newpage}}
-This macro forces a \indx{page eject} if not on a new page.\note{\tenpoint
-If {\tt \+newpage, \+oddpage}, or {\tt \+evenpage}
-occur at the bottom of a full page, they will cause an extra page
-eject.  If this happens, insert an {\tt \+eject} just before the
-page command.}
-
-\cmd{\indx{oddpage}}
-This macro causes a page eject, and if the current page is an odd-numbered
-page, leaves an extra blank page so that the following text is
-guaranteed to begin on an odd-numbered page.
-
-\cmd{\indx{evenpage}}
-This macro is similar to oddpage, but the following text will appear on
-an even rather than an odd numbered page.
-
-The {\bo plain} \TeX\ command, {\tt\+pageno} will set the current page number
-to the specified page number.  (See ``Some Useful \TeX\ Commands'' in
-Chapter~2 of this manual.)
-
-\level2{Paragraph Style}
-As \TeX\ accepts text from the input file, the text is formatted into
-paragraphs. The following commands can be used to control the shape
-of the paragraphs.
-
-
-\cmd{\indx{inset}=\dim}
-Specifies a general amount of indentation to be used with itemized
-lists, notes, warnings and indent blocks. Default is 0.5
- inch.
-
-\need.5in\bigskip\relax{{\tentt \+start\[indent\]}}\lbreak
-      \relax{{\tentt \+finish\[indent\]}}\lbreak
-These commands are used to indent the left margin by the inset
-dimension. The right margin is unaffected by this block.
-
-\cmd{\indx{indentspace}=\dim}
-This command assigns the indentation value for the first line of all succeeding
-paragraphs when {\tt\bs indentstyle} is in effect. The default is
-20 points.
-
-\cmd{\indx{indentstyle}}
-This causes the first line of each paragraph to be indented
-(the amount of the indentation is assigned by the {\tt\bs indentspace}
-command). This is the default paragraph style.
-
-\cmd{\indx{noindentstyle}}
-This causes the paragraphs to be formatted with no indentation.
-The nominal \indx{spacing} between paragraphs is 5 points greater without
-indentation than when {\tt\bs indentstyle} is being used.
-\start{note}
-\centerline{-- NOTE --}
-Spacing between paragraphs can be user specified by using the {\tt
-\bs parskip} command.
-\finish{note}
-
-\level2{Itemized and Bulleted Lists}
-The following macros are aids in producing lists. The various list commands
-cause indentation at various levels and use various tokens (numbers, letters,
-dots, dashes, $etc.$) to the left of the
-first line of the listed item to set off the list entry.
-
-\need.5in\bigskip\relax{{\tentt \+numbereditems}}\lbreak
-      \relax{{\tentt \+lettereditems}}\lbreak
-      \relax{{\tentt \+Lettereditems}}\lbreak
-      \relax{{\tentt \+romanitems}}\lbreak
-      \relax{{\tentt \+Romanitems}}\lbreak
-      \relax{{\tentt \+squareditems}}\lbreak
-      \relax{{\tentt \+dotteditems}}\lbreak
-      \relax{{\tentt \+dasheditems}}\lbreak
-These macros initialize the tag allocation macro {\tt\bs itemtag}.
-Default is {\tt\bs numbereditems}.
-
-\need.5in\bigskip\indx{{\tentt \+numberedsubitems}}\lbreak
-      \relax{{\tentt \+letteredsubitems}}\lbreak
-      \relax{{\tentt \+Letteredsubitems}}\lbreak
-      \relax{{\tentt \+romansubitems}}\lbreak
-      \relax{{\tentt \+Romansubitems}}\lbreak
-      \relax{{\tentt \+squaredsubitems}}\lbreak
-      \relax{{\tentt \+dottedsubitems}}\lbreak
-      \relax{{\tentt \+dashedsubitems}}\lbreak
-These macros initialize the tag allocation macro {\tt\bs subitemtag}.
-Default is\lbreak {\tt\bs letteredsubitems}.
-
-\cmd{\indx{itemtag}}
-This macro causes a number, letter, roman numeral, square, dot or dash
-to be printed as the item specifier
-depending upon what initialization has taken place (see above).
-
-\cmd{\indx{subitemtag}}
-Similar to {\tt\bs itemtag} but pertains to subitems.
-
-\cmd{\indx{square}}
-This macro prints a .4em-by-.4em square ( \square\ ). This macro can be used at
-any time a horizontal list is being built (such as the middle of a
-paragraph),
-but it is particularly useful as the argument for the {\tt\bs itemlist} macro.
-(This command produces the same symbol as \TeX 's {\tt \+bull} command.)
-\cmd{\indx{dott}}
-This macro prints a solid round dot ( \dott\ ). (Same as {\bo plain} \TeX 's
-{\tt \$\+bullet\$}.)
-
-\cmd{\indx{emdash}}
-Sets a horizontal rule one ``\indx{em}'' long ( \emdash\ ).
-
-\cmd{\indx{itemlist}\[\hor\]}
-This macro introduces an item of a list by indenting both left and right
-margins by the \dim\ specified in the last {\tt\bs inset} command.
-The \hor\ is inserted within braces to specify the token
-which is to set off the text. If the token has already been
-specified (using {\tt \bs dotteditems, \bs Romanitems}, $etc.$),
-or the default {\tt \bs numbereditems} is acceptable,
-then the command {\tt \bs itemtag} can be inserted here.
-The text of the item follows.  (The text
-does {\bo not\/} need to be enclosed within braces.)
-Indentation continues only for the duration
-of one paragraph (if more than one paragraph is desired in an
-item, {\tt\bs itempar} should be used).
-The use of {\tt\bs itemlist} resets the subitem tag.
-
-\cmd{\indx{subitem}\[\hor\]}
-This macro is similar to {\tt\bs itemlist}, but the indentations are twice as
-large as for {\tt\bs itemlist}. This can be used to indicate a
- second level of list. (See {\tt \bs itemlist} for contents of
- the \hor .
-
-\need.5in\bigskip\relax{{\tentt \+itempar}}\lbreak
-      \relax{{\tentt \+subitempar}}\lbreak
-These macros are used to start new paragraphs within an item or
-subitem respectively.
-
-\cmd{\indx{enditems}}
-This commands properly ends an itemized list by resetting the item counter
-and appending {\tt\bs bigskip} \indx{glue}.
-
-\cmd{\indx{itm}}
-Similar to {\tt\bs itemlist\[\bs itemtag\]} except that a
-period is appended to the tag if it is a letter, number
-or roman numeral. With this command, the item tag must be
-specified ahead of time using the command
-{\tt \bs dotteditems, \bs lettereditems}, $etc.$, unless the
-default ({\tt \bs numbereditems}) is acceptable. Again,
-{\tt\bs itm} will {\bo not} accept any \hor\
-as an item tag specifier.
-
-\cmd{\indx{sitm}}
-Similar to {\tt\bs itm} but pertains to subitems. Like
-{\tt\bs itm}, {\tt\bs sitm} will {\bo not}
-accept any \hor\ as a subitem tag specifier. The subitem tag must
-be specified beforehand, unless the default
-({\tt \bs letteredsubitems}) is acceptable.
-%\need3in
-\start{note}
-\centerline{-- NOTE --}
-If you enter a local \indx{block structure} prior to setting an itemized list,
-and want to exit that structure immediately after your last item, then
-you must first be sure that you are in {\bo \indx{vertical mode}}.
-Otherwise, the last item may not be indented properly.
-
-Three ways to accomplish this are by using {\tt\bs enditems,
-\bs vskip}, or {\tt\bs par}. \finish{note}
-
-\level2{Line Specifier Macros}
-The content of individual lines can be controlled, and they can be
-centered or justified using the following
-commands.
-
-\cmd{\indx{centerline}\[\hor\]}
-This takes the text within the brackets and centers it between the
-margins. The line does not count as a paragraph, so the normal
-interparagraph space is not inserted above the line. If this command
-follows a paragraph, it is
-usually appropriate to precede it with a {\tt\bs vskip}. This command
-has been redefined from {\bo plain} \TeX\ in that it uses the
-HP macro {\tt \+lline} (described below), so {\tt \+leftskip}
-and {\tt \+rightskip} values are taken into account.
-
-\cmd{\indx{lline}\[\hor\]}
-This is very similar to the plain \TeX\ {\tt\+line} command
-in that it creates a horizontal box that is the width of the current
-{\tt\+hsize}, except that {\tt\+lline} takes into account
-the values of {\tt\+leftskip} and {\tt\+rightskip}
-if they have been specified.  In other words {\tt\+lline}
-stays within the current margins. The \hor \ is the contents of
-the horizontal box.
-
-
-\cmd{\indx{leftline}\[\hor\]}
-This left justifies the contents of the \hor . The comments about vertical
-spacing above apply here, also. This command has also been redefined
-to use {\tt \+lline} (see {\tt \+centerline}, above).
-
-\cmd{\indx{rightline}\[\hor\]}
-This right justifies the contents of the \hor . The comments about vertical
-spacing above apply here, also. This command has also been redefined
-to use {\tt \+lline} (see {\tt \+centerline}, above).
-
-\cmd{\indx{raggedright}}
-The {\tt\bs raggedright} macro causes paragraphs to be formatted
-in such a way that they are not necessarily justified
-on the right margin. This command has also been redefined from
-{\bo plain} \TeX\ in that {\tt \+rightskip} values are preserved.
-
-\cmd{\indx{justify}}
-This macro has the opposite effect of the {\tt\bs raggedright} macro
-and causes the text to be right justified
-({\tt\bs justify} is the default in HP \TeX ).
-
-\level2{Boxes}
-
-\cmd{\indx{boxline}=\dim}
-This macro assigns the width of the lines used for {\indx{boxes}. The default
-boxline dimension is 0.01332 inch.
-
-\cmd{\indx{boxspace}=\dim}
-This macro assigns the width of the space between a boxed item and
-the line of the box. The default width in HP \TeX\ is 5 points.\super{4}
-
-\cmd{\indx{boxit}\[\hor\]}
-This macro encloses the argument in a box. If encountered
-while making a line of text, the box's bottom line will
-be along the baseline of the text. The \hor\ may contain multiple
-lines separated by {\tt\bs cr} to be centered within the box. Note
-that each line is then treated as a {\bo group}, so font changes,
-$etc.$~on one line will not affect the next line.
- When using this command, the \hor\ will be
-raised somewhat above the line, \boxit{like this.}
-If you desire that the text not be raised above the baseline,
-use the {\tt\bs textbox} command (described below).
-
-\cmd{\indx{textbox}\[\hor\]}
-This command causes a box to be placed around the \hor ,
-{\bo without} altering the text, \textbox{like this.} A
-textbox cannot be broken from one line of text to another.
-
-\cmd{\indx{centerbox}\[\hor\]}
-This macro centers a box horizontally on the page
-and inserts space above and below.
-Multiple lines can be specified using {\tt\bs cr} (see
-{\tt \bs boxit} description). A {\tt \+centerbox} within a
-  {\tt \+centerbox} will not work, but {\tt \+boxit} inside
- {\tt \+centerbox} will.
- %\need1.25in
-\level2{Notes and Warnings}
-Two other text structures available with the HP \TeX\ macro package are notes
-and warnings.
-
-\need.5in\bigskip\relax{{\tentt \+start\[note\]}}\lbreak
-      \relax{{\tentt \+finish\[note\]}}\lbreak
-A note is inset twice the {\tt\bs inset} dimension on both margins and
-set apart from the rest of the text by extra vertical space.
-If a note would otherwise start less than half an inch from the
-bottom of a page, a page eject is performed prior to the note.
-{\tt\bs finish\[note\]} signifies the end of the note.
-
-\need.5in\bigskip\relax{{\tentt \+start\[warning\]}}\lbreak
-      \relax{{\tentt \+finish\[warning\]}}\lbreak
-A warning is similar to a note, except that is also set apart by horizontal
-rules above and below the text. {\tt\bs finish\[warning\]}
-signifies the end of the warning text.
-
-\level2{Verbatim Mode}
-Verbatim mode will cause text to be printed ``as is,''
-without any justification. Special characters in this mode
-are the backslash (\bs ) and the curly brackets (\[), (\]).
-Most other characters can be used and will be printed \indx{verbatim}.
-
-Verbatim mode is intended for use with simple text which does
-{\bo not} contain a large number of control sequences.
-The reason for this restriction is that there are many
-characters (such as a space, a \indx{tilde}, $etc.$)
-which take on different meanings in verbatim mode.  Some of these may be
-imbedded within a control sequence and can cause
-problems when they are expanded.
-
-You will usually want to select a ``non-proportionally spaced''
-font (like ``tt'') for use in verbatim mode.  The
-reason for this is that ``proportional fonts'' (like ``rm'')
-will cause the printed output to be aligned differently
-than what appears on the CRT during source file typing. Other
-non-proportional fonts available with the HP 2688A Laser Printer
- are Courier, Gothic, Pica, Script, Prestige and Line Printer.
-
-\start{note}
-\centerline{-- NOTE --}
-Although verbatim mode using \indx{non-proportional fonts} will
-{\bo usually} produce output
-that exactly matches what you see on the CRT, there is
-at least one exception to this.  Long sequences of characters
- may be spaced
-slightly differently than a string
-of blank spaces of identical length .  This is
-a result of the rounding anomalies that occur when \TeX 's
-{\bo ideal} character sizes are converted to the printer's
-{\bo actual} sizes.
-\finish{note}
-\cmd{\indx{start\[verbatim\]}}
-This macro causes the following text to be printed ``verbatim''
-without any justification.
-
-\cmd{\indx{finish\[verbatim\]}}
-This macro ends the verbatim mode described above.
-
-%\need1.25in
-\level2{Paragraph Levels}
-These macros can be used to create \indx{paragraph headings}
-of four different levels.
-The \hor, and page number can be written
-to the file \lb{\sa jobname}\rb\lower.3em\hbox{*}
-to be used for a table of contents (the asterisk ``\lower.3em\hbox{*}''
-signifies the {\tt contents} file).
-
-The command {\tt\+ctswrite\hor} will automatically open a file and write the
-\hor\ and the page number to the file.  The {\tt\+contents} command
-then uses the \lb{\sa jobname}\rb\lower.3em\hbox{*} file to
-create the \indx{table of contents} (refer to the {\tt\+contents} command
-description in this section).
-
-\cmd{\indx{level}\lb\sa integer between 1 and 4\rb\[\hor\]}
-This is the command used to print a paragraph heading.  Whatever
-format is specified using the commands listed below ({\tt \+firstlevelhead,
-\+secondlevelhead}, $etc.$) will be used. For example, the command used to set
-the paragraph heading of this section looked like this:
-
-\centerline{\tt \+level3\[Paragraph Levels\]}
-
-The {\tt \+level} command will automatically update the {\tt\bs levelno}
-to print the paragraph head.
-
-\need.5in\bigskip\relax{{\tentt \+firstlevelhead}}\[\hor\]\lbreak
-\relax{{\tentt \+secondlevelhead}}\[\hor\]\lbreak
-\relax{{\tentt \+thirdlevelhead}}\[\hor\]\lbreak
-\relax{{\tentt \+fourthlevelhead}}\[\hor\]\lbreak
-These commands specify the tokens that are inserted to format
-each of the various head levels. They should be used when the
-default conditions of HP \TeX , as described below,
- are not satisfactory. A control sequence {\tt \bs title}
-is defined to be the \hor\ from the corresponding {\tt \bs level}
-command. For example, the command:
-\start{verbatim}\tt{\hfuzz=31pt
-         \+secondlevelhead\[\+need.75in\+bigskip\+leftline\[\+fourteenbf%
-              \+levelno\+enspace\+title\]\+medskip%
-              \+ctswrite\[\+hskip15pt\+tenrm\+title\]\]}
-    \finish{verbatim}
-\vskip3pt\noindent
- would cause all second level paragraph heads to be printed on
-a new page if less than .75 inch remains on the current page.
-The title will be left justified in fourteen point boldface
-type. The level number is followed by an ``enspace.''
- ``Bigskip'' \indx{glue} is inserted before the title with a ``medskip''
-after.  The \indx{{\tentt\+ctswrite}} command specifies how the
-level heading will be written in the table of contents, as
-described below.
-
-Whenever you define a {\tt \bs firstlevelhead, \bs secondlevelhead}, $etc.$,
-command to specify the formatting of paragraph headings, you must also
-specify how it will be written in the table of contents (if
-you plan to create one).  The command for doing this is
-{\tt \bs ctswrite}.  For example, the fourth level head was
-redefined from the HP \TeX\ defaults in this document, and the
-contents writing command was used as follows:\lbreak
-\centerline{\tt \bs ctswrite\[\bs hskip45pt\bs ninerm\bs title\]}
-This causes all fourth level headings in the table of contents
-to be inset 45~points and be written in nine--point roman type.
-
-The default HP \TeX\ paragraph level headings
-are formatted as follows: {\tt \bs level1} begins on a new page,
-prints the title in 14 point bold face type and down 1.5 inches
-from the top of the page. {\tt \bs level2}
- requires that at least .75 inch remain on the
-page. If so, the title is printed with some vertical space above it,
-otherwise, it is set on the top of the next page. In any case, it is printed
-in 12 point boldface type. {\tt \bs level3} and
-{\tt \bs level4} are similar, but
-require less space to remain on the page and print the title in 10
-point bold face and 10 point roman respectively.
-
-The ``levelhead'' macros are {\bo local} to
-their \indx{block structure}.  This provides a simple means
-to return to the HP \TeX\ default levelhead
-style.  All you would need to do is enclose the command
-and any text you want affected within braces.  After the
-closing brace, \TeX\ will return to the default format. Note
-that this should only be attempted for {\bo shorter} blocks.
-Creating large blocks of several pages in length can cause
-\TeX\ to run out of memory.
-
-
-\start{note}\centerline{-- NOTE --}
-If you need to change the font style or size within a level
-heading, you must specify the {\bo entire} font name,
-(for example: {\tt \bs tentt}$\ldots$ not {\tt \bs tt}).
-\finish{note}
-\cmd{\indx{levelno}}
-This macro can be used whenever the author desires the number
-of the heading to appear in the document. The number of the
-various levels of headings appear, separated by periods.
-For example, typing {\tt Section \bs levelno} might result
-in: Section 1.2.7.1 if this was the first fourth-level heading
-of the seventh third-level section of the second$\ldots$ $etc.$
-Levels lower than the last modified level do not appear in
-{\tt\bs levelno}.
-
-\def\delim{.}
-\cmd{\indx{setlevelno}\[\int\delim\int$\ldots$\int\]}
-This macro can be used for presetting the one through
-four heading numbers. If you use
-this command before a {\tt\+level} command, then the
-counter will increment to the next number when the
-{\tt\+level} command is encountered. Therefore, you
-should preset to one number below the desired level.
- You cannot preset the level 2 counter without
- specifying the level 1, or the level 3  without level 1 and 2
- and so on. (For example, you cannot specify {\tt\+setlevelno\[1.~.~.4\]},
- you must specify {\tt \[1.\int .\int .4\]}.)
-
-\cmd{\indx{contents}}
-This macro forces a page eject and produces a \indx{table of contents}
-on the following pages as dictated by the previous heading macros.
-No vertical \indx{glue} is inserted, so you may want to use a {\tt \bs vfil}
-command immediately before {\tt \bs contents}.
-
-\need.5in\bigskip\relax{{\tentt \+topofcontents}}\[\ver\]\lbreak
-      \relax{{\tentt \+botofcontents}}\[\ver\]\lbreak
-These macros specify a list to be placed above and below the table of
-contents. The \ver\ may include logos, rules, $etc.$ The table of contents
-is quite rigid, so a {\tt\bs vfill} is appropriate in at least one \ver.
-Defaults in HP \TeX\  will format the table of contents as they appear in the
-beginning of this manual (with the exception of the headings).
-\start{note}\need1in
-\centerline{-- NOTE --}
-{\tt\+topofcontents} and {\tt\+botofcontents} must
-{\bo both} be specified {\bo before} the
-{\tt\+contents} command is used. (That is, you cannot
-specify {\tt\+botofcontents} after {\tt\+contents},
-even though this seems logical.)
-\finish{note}
-\level2{Multiple Columns}
-
-The following macros control the number of columns on the page.
-Multiple column and single column text can be mixed on a page by
-using the following commands.
-
-\cmd{\indx{columnspace}=\dim}
-This command specifies the amount of space between columns on a page.
-This dimension should be assigned before entering multicolumn mode and
-should remain unchanged for the duration thereof. The default
-column space in HP \TeX\ is 0.5 inch.
-
-\need.5in\bigskip\relax{{\tentt \+start\[twocolumns\]}}\lbreak
-      \relax{{\tentt \+start\[threecolumns\]}}\lbreak
-      \relax{{\tentt \+finish\[twocolumns\]}}\lbreak
-      \relax{{\tentt \+finish\[threecolumns\]}}\lbreak
-These four commands cause the text to be formatted into multiple columns.
-If a {\tt\bs balance},
- {\tt\bs newpage}, {\tt\bs evenpage} or {\tt\bs oddpage} macro is
-encountered while in multicolumn mode, the columns are balanced
-on the page prior to the page eject. Exit from multicolumn mode
-causes the columns to be balanced as well. Unbalanced columns may
-be obtained by using {\tt\bs vfill} {\tt\bs eject} while in multicolumn mode.
-Balancing forces the top lines of each column to be lined up. The
-bottom lines are lined up as well unless {\tt\bs raggedbottom} has been
-specified. Discardable items (such as glue, penalties, $etc.$)
-immediately following these commands will be ignored. (To prevent
-this, you may use {\tt\+null} immediately
-after {\tt\+finish\[$n$columns\]}.)
-
-\cmd{\indx{balance}}
-This command causes the columns to become balanced. Discardable
-items (such as \indx{glue}, penalties, $etc.$) immediately following these
-commands will be ignored. (To prevent
-this, you may use {\tt\+null} immediately
-after {\tt\+finish\[$n$columns\]}.)
-
-
-\start{note}
-\centerline{-- NOTE --}
-When using multiple columns, you may find it helpful to use the
-plain \TeX\ commands {\tt\+tolerance} and
-{\tt\+hbadness} (to increase the stretch and
-shrinkability of interword \indx{glue} and decrease complaints
-regarding ``underfull hboxes''). See {\tenit The
-\TeX book} for more information.
-\finish{note}
-
-\level2{Tables}
-The following macros are useful for setting \indx{tables}. These
-macros are different from the plain \TeX\ {\tt\bs halign} and
-{\tt\bs valign} commands in that
-they format one row at a time. The table can be justified as a whole
-either left, right or centered. As long as the number of columns
-in each entry remains constant, the entire table appears justified.
-(Interesting figures, such as pyramids, hopscotch boards, $etc.$ can
-be produced by changing the format and the number of
-columns in each entry.)
-Each column of the table has its own user specified width.
-Between each column
-is a vertical line (which can be easily made invisible).
-This vertical rule takes no space from any column so the rule
-width may be varied without altering the column dimensions.
-An entry may also be designed to span two or three columns.
-Horizontal bars are
-treated exactly the same as data entries. The macro \indx{{\tentt\bs tbar}}
-can be used to produce such a bar.
-
-\cmd{\indx{tableline}=\dim}
-This parameter specifies the dimension of bars and rules in
-all subsequent entries. This parameter should remain unchanged
-throughout the entire table. Default value is 0.01332 inch.\super{7}
-\start{note}
-\centerline{-- NOTE --}
-There may be some occasion when printing a table that you
-get the error message,\lbreak
-~~~~``{\tt Printer error: \lbreak
-~~~~**Could not process all the data, data lost.}''\lbreak
-The printer uses a variety of different length line segments to
-``build'' a line.  If the {\tt tableline} specification you have
-chosen requires too many individual segments to make up the exact
-specification, it may cause this error.
-There are a few remedies available, as follows:
-
----If you are using the default magnification (1.0), then
-try using the default {\tt tableline} dimension (just leave out
-the {\tt\+tableline} command.
-
----If you are using a file magnification value other than 1.0, then alter
-your {\tt\+tableline} specification so that its value, when converted
-to dots (multiply length in inches $\times\ 300$), is a power of 2 ($i.e.$ 1, 2,
-8, 16, 32 or a multiple of any of these except 1).
-\finish{note}
-
-\cmd{\indx{tablespace}=\dim}
-This parameter specifies the minimum amount of space to be placed
-between the vertical rules and data entries in the table. Default in
-HP \TeX\ is 5 points.
-
-\cmd{\indx{tableformat}\[\tspec|\colspec\dim|$\ldots$|\colspec\dim\]}
-This command specifies the table format. Note that a \indx{vertical bar}
-(\indx{{\tentt |}}) is required as a separator
-between specifications, but not at the beginning or end of the
-list (different than {\tt \+tablerow} or {\tt \+tablebar}).
-
-\tspec\  can be any of {\tt\bs leftline}, {\tt\bs rightline},
- or {\tt\bs centerline}. \colspec\ can be any of
-{\tt\bs leftline}, {\tt\bs rightline}, {\tt\bs centerline} or
-{\tt\bs paragraph}. Other options are
-allowed if you make them yourself; for example, if you type:
-\par\vskip3pt
-\centerline{\tt\bs def\bs mything\#1\[\bs line\[\bs hskip 1in \#1\bs hss\]\]}
-\par\vskip3pt
-\noindent then {\tt\bs mything} would be a valid \tspec\ option that
-would print the table 1 inch from the left margin.
-The \colspec\ is always a single token ({\tt\bs leftline}, {\tt\bs rightline},
-{\tt\bs centerline} or {\tt\bs paragraph}), and is
-followed by a dimension. The token specifies the standard
-justification of the column ({\tt\bs paragraph} must be used if the
-column is to contain paragraphs), and the dimension specifies the
-absolute width of the column. Again, if you are not satisfied with the
-selection you can make your own---the rules are that the macro consume
-one token (containing the text) and produce a box of width {\tt\bs hsize}.
-%\need2in
-\start{note}
-\centerline{-- NOTE --}
-If the {\tt\bs paragraph} column specification is used, {\tt \+parskip}
-must be 0 points (this is the default).  Otherwise, the paragraph entry
-will be raised or lowered by the current {\tt \+parskip} amount and the
-table will be out of alignment.  If you are using {\tt\+noindentstyle}
-and have not reset {\tt\+parskip}, then inserting an {\tt\+indentstyle}
-command just prior to the table will return to the proper (0 points) parskip.

-These commands are used to build tables. {\tt\bs tablerow} should
-be used if the \col\ contains text, while {\tt\bs tablebar} should
-be used for bars or other non-text entries. Horizontal bars are
-obtained by using either {\tt\bs vrule height} \dim , {\tt width} \dim\
- or {\tt\bs tbar}
-as a \col\ ({\tt\bs tbar} uses {\tt\bs tableline} as the rule height).
-The following syntax holds true for both macros:\dotteditems
-
-\itm A \indx{vertical bar} (\indx{{\tentt |}}) or a \indx{tilde} (\~{}) must be
-beginning and end of each column, including the first and last entry
-(differs from {\tt \+tableformat} syntax).
-\itm The \indx{vertical bar}s ({\tt |}) may be replaced by tildes (\~{})
-if a visible vertical bar in that position is not desired.
-
-\itm If the first thing in a \col\ happens to be the control sequence
-\indx{{\tentt \bs span}}\[\int\]{\tt \bs tbar}, then the number
-of columns specified
-as \int\ are spanned by the entry (in this case a horizontal bar). The
-natural justification for the spanned entry will be that of the
-leftmost column spanned. (Note that {\tt span}\[\int\] is
-{\bo not} followed by a blank space as this can cause difficulties.)
-%\need1.25in
-\start{note}
-\centerline{-- NOTE --}
-While building tables, if a {\tt\+tablebar} or {\tt\+tablerow}
-runs more than one line of text (on the CRT), it is good practice
-to use the percent
-sign (\indx{{\tentt \%}}) at the end of each line.  This will tell \TeX\ to
-ignore anything else on that line and prevent
-possible problems with extra spaces being
-misinterpreted by \TeX .
-\finish{note}
-\level2{Fonts}
-Only a few fonts are preloaded in HP \TeX. These macros allow you
-to access a variety of font families, styles, and sizes.
-
-\cmd{\indx{fontdef}\bs\lb{\sa command}\rb=\[\lb{\sa library}\rb,%
-    \lb{\sa font name}\rb\]}
-This command equates a command of your choice with a
-font (as used in the library). You can use \lb{\sa library}\rb
-(optional) to
-specify other than the default font library.
-This command differs from \TeX's {\tt\+font} command in that the
-font won't actually be loaded until
-the first request (if any).

-\indx{slanted},
-\indx{sans serif}, and \indx{typewriter} style.
-
-If the selected font is undefined, the font style is changed
-to roman. If that new font is still undefined, the size is

-\level2{Miscellaneous Macros}
-
-%\cmd{\indx{indx\[\hor\]}
-%This command sets the \hor. The \hor\ along with the current page
-%number are then written to the file {\job.inx} for use as an index.
-%
-\cmd{\indx{note}\[\hor\]}
-This macro puts a footnote at the bottom of the current page
-and inserts a superscript footnote number at the location
-of the command and the footnote.
-Footnote numbers are allocated starting with~1 and can be
-reset by the use of {\tt\bs resetnotes}. The \hor\ is the footnote
-text.
-
-
-\cmd{\indx{need}\dim}
-The result of this macro is that if the page breaking algorithm
-of \TeX\ determines that the current position would optimally
-fall within \dim\ of the bottom of the page, the page is broken
-leaving some empty space at the bottom.
-\need1in
-\start{note}
-\centerline{-- NOTE --}
-Since the {\tt \bs need} command uses a negative penalty
-to {\bo encourage} (not {\bo force})  \TeX\ to break
-the page, it will
-not always have the effect you might anticipate. This is especially
-true if the command is encountered near
-the top of the current page and the remaining text will not
-adequately fill the current page.
-\finish{note}
-\cmd{\indx{super}\[\hor\]}
-The argument is printed as a superscript.
-
-\cmd{\indx{sub}\[\hor\]}
-The argument is printed as a subscript.
-
-\cmd{\indx{lbreak}}
-This macro forces a line break within a paragraph. It inserts ``hfil''
-\indx{glue} before the break, so the line will {\bo not} be right
-justified.  If you want right justification, use plain \TeX 's
-{\tt \bs break} command.
-
-\cmd{\indx{uline}\[\hor\]}
-This macro causes the argument to be underlined.
-
-\cmd{\indx{mon}}
-This command prints the current month name. For
-example, if the current month were August, {\tt\bs mon} would
-print the letters ``August'' in the current font.
-
-\cmd{\indx{date}}
-This command prints the current date in the format Month Date, Year.
-For example, if today's date were 12 December 1984, {\tt\bs date}
-would print the characters ``December 12, 1984'' in the current font.
-
-\cmd{\indx{hour}}
-This command prints the current time of day (for example -- 4:07 PM)
-
-\level2{Block Structure}
-Certain local document styles are considered to belong to a ``block.''
-(\indx{Block structure}, as used here, simply refers to a portion of a
-file that has some common formatting instructions applied
-to it.)\note{\tenpoint The concept of {\tenbo \indx{grouping}}, explained
-in this manual and in {\it The \TeX book}, is basically the
-same as the ``\indx{block structure}'' referred to here.}
-
-The current block is defined to be the most recently opened
-block. Pending blocks are blocks that have been opened but
-not closed. The HP \TeX\ macros {\tt\+start} and {\tt\+finish}
-are used to open and close blocks.
-
-Valid \blk s pre-loaded in HP \TeX\ include {\tt indent, note,
-  warning, ver\-ba\-tim, twocol\-umns} and {\tt threecolumns},
-  all of which have been described in this chapter.
- User defined blocks may be implemented by defining  a control
- sequence, {\tt\bs BEGIN\blk} and, optionally, another
- control sequence, {\tt\bs END\blk}.
-
-\cmd{\indx{start}\[\blk\]}
-This command determines if a control sequence {\tt\+BEGIN\blk} has
-been defined.  If one exists, a new block is opened and the control
-sequence is invoked.  Otherwise, an \indx{error message} is issued and the
-command is ignored.
-
-\cmd{\indx{finish}\[\blk\]}
-This command is used to close the current block and invoke the
-control sequence {\tt\+END\blk} if one has been defined. If \blk\ matches
-the current block name, the current block is closed. If not, an
-appropriate error message is issued and corresponding corrective
-action is taken. If \blk\ is not valid or there are no pending
-blocks, the command is ignored. If \blk\ is valid but does not
-match the current block
-name, {\tt\bs done} commands are inserted until either \blk\ matches
-the current block name or until all pending blocks are closed.
-
-\cmd{\indx{done}}
-This command closes the current block without
-any error checking and invokes the control sequence {\tt\+END\blk} if
-one has been defined. A \TeX\ error message will be issued if
-there are no pending blocks.
-
-Following is an sample usage of the {\tt\+BEGIN} and {\tt\+END}
-commands in creating user-defined blocks:
-
-\def\BEGINexample{\bigskip\centerline{- EXAMPLE -}
-                \medskip\leftskip.75in\rightskip.75in}
-\def\ENDexample{\medskip}
-\start{example}
-This example was created by defining the following block:\medskip
-\centerline{\tt \+def\+BEGINexample\[\+bigskip\+centerline\[- EXAMPLE -\]}
-\centerline{\tt ~~~~~~\+medskip\+leftskip.75in\+rightskip.75in\]~~~~~~}
-\medskip
-The block was opened using the command: {\tt\+start\[example\]}. The
-optional control sequence {\tt\+END\blk} was also used, as follows:\medskip
-\centerline{\tt \+def\+ENDexample\[\+medskip\]}\medskip
-The {\tt\+medskip} vertical glue will be inserted after the block is
-closed using the command: {\tt\+finish\[example\]}.
-\finish{example}

-\level1{\indx{HP 2688A} Control Macros}
-
-These macros are for controlling certain features of the 2688A Laser
-Printer:
-
-\level2{Page Copy Control}
-
-\cmd{\indx{copies}\int}
-This macro assigns the number of copies per page starting with the current
-page. The copies are uncollated; in other words, if {\tt\bs copies5}
-occurred on page 3, the output will have five copies of page 3,
-then five copies of page 4, $etc.$ The control of the number of copies
-is accomplished through one of \TeX's counters.  Default is counter
-number~1.  Possible integers and their effect are shown below:
-\itm 1 to 32,767 will produce the specified number of copies.
-\itm Greater than 32,767 will produce 32,767 copies.
-\itm 0 will produce 1 copy.
-\itm Less than 0 (negative number) no copies (can be used
-to suppress certain sections of a document, $etc.$)
-\enditems
-The counter
-can be changed using the following macro.
-
-\cmd{\indx{selectcopycounter}\lb {\sa integer from 0 to 9}\rb}
-This is used for changing which counter is used for controlling
-the number of \indx{copies} per page (default is 1). This command generally
-should not be used except by people who are writing their own
-macros.
-
-\need.5in\bigskip\relax{{\tentt \+copieson}}\lbreak
-      \relax{{\tentt \+copiesoff}}\lbreak
-If the multiple copies feature is being used in a document, these
-macros can be used to alternate between one copy per page and the
-number of copies assigned by the {\tt\bs copies} macro. The difference between
-{\tt\bs copiesoff} and {\tt\bs copies1}~is that when the former is followed
-with {\tt\bs copieson}, the original number of copies is restored, whereas
-when the latter is followed with {\tt\bs copieson}, there is,
-of course, no effect.
-
-\level2{Logical Page Control}
-
-The Print Server features a concept called ``\indx{logical paging}''
-which is controlled using the following set of macros. A
-logical page is a rectangular addressing space on the sheet of paper
-(referred to as the ``\indx{physical page}''). Logical pages have an
-orientation (\indx{portrait}, \indx{landscape}, \indx{reverse portrait}
-or \indx{reverse lanscape}) and a position on the physical page.
-Through the operator
-interface of PS2688A, you may define a list of logical pages that
-may be written to on any sheet of paper.
-These logical page specifications may also be stored in a PS2688A
-input file to avoid typing in the specifications for each job.
-Using these macros, you
-can address the logical pages with either of two methods:
-either by explicitly specifying a logical page for each page of
-\TeX\ output, or by specifying an ordered list of logical pages
-and letting the system cycle through the list.
-
-\cmd{\indx{lpdef}\[\lb\sa logical page definition\rb\]}
-This command defines a logical page size and orientation.  The
-\lb{\sa logical page definition}\rb
-consists of the logical page
-number, followed by the {\bo left},
-then the {\bo top} dimensions (distance from the
- edges of the physical page), and the
-\indx{logical page orientation} (portrait, landscape, rev--portrait or
-rev--landscape). Orientation may be abbreviated {\tt P,L,RP,}and
-{\tt RL,} respectively, and either upper or lower case
-characters will work. The edges of the page that
-would normally be the top and left as viewed from that
-logical page's orientation are
-always considered top and left in this context.
- An example usage follows:\medskip
-\centerline{\tt \bs lpdef \[1, 1.5in, 3in, L\]}\medskip
-This would cause logical page number 1~to be printed
-in {\bo landscape} orientation, with the left edge of the
-print (as viewed from landscape orientation) beginning 1.5~inches
-from the edge of the physical page.  The ``top'' (left-hand
-edge along the paper path) will begin 3~inches from the
-edge.
-
-The default values for logical pages in HP \TeX\ are: LEFT=1in,
-TOP=1in.
-
-
-
-
-\start{note}
-\centerline{-- NOTE --}
-The dimension specified as distance from the top edge does not
-take into account the space needed for headings.  If running headings
-are to be used, the logical page definition should allow extra
-room for them when specifying ``top'' dimension. (Footings
-are also printed ``in the margin,'' so when specifying
-{\tt vsize} be sure to leave room for them.)
-\finish{note}
-
-\cmd{\indx{lplist}\[\lb\sa logical page list\rb\]}
-This command specifies the logical page list to be used whenever
-logical pages are being used implicitly. Only one such
-specification is allowed within a document, if more than one exist,
-all but the last are ignored. This command initializes
-implied logical paging.
-
- The \lb {\sa logical page list}\rb ~is a list
-of integer numbers from 1~to 32~which have been defined
-using the {\tt \bs lpdef} command. Positive number entries will
-cause a physical page eject prior to initiating the logical
-page entry.  Negative numbers require no such physical
-page eject.  Each entry number should be separated from
-the next by a comma.
-
-%\need3in
-\medskip The remaining commands control explicit logical paging. If any of
-these commands occur within a page, a page eject is issued and the
-next page to be printed will be dependant upon the particular
-command. If any of these commands occur on the top of a page, the
-prescribed action will be delayed until the next page break
-(be it natural or forced by a {\tt\bs newpage}, {\tt\bs eject}, $etc.$).
-For example, suppose the first page of every chapter in a
-document uses logical page 5, then {\tt\bs ppageto5} {\tt\bs lpresume}
-would eject the current page (assuming it is not empty), issue
-a physical page eject and begin printing on page 5. Later,
-when the page is full, \TeX\ breaks the page and resumes printing
-according to the logical page list.
-
-\cmd{\indx{lpageto}\lb {\sa integer between 1 and 32}\rb}
-This command causes the next page to be printed on the specified
-logical page. No physical page eject is implied.
-
-\cmd{\indx{ppageto}\lb {\sa integer between 1 and 32}\rb }
-This command is similar to {\tt\bs lpageto} but implies a physical
-page eject prior to printing on the specified logical page.
-
-\cmd{\indx{lpresume}}
-This command is used after a {\tt\+ppageto}  or {\tt\+lpageto}
-command to resume
-printing on the current page of the logical page list.
-
-\cmd{\indx{lpreset}}
-This command resets the logical page list and prints on the first
-page in the list.
-
-\cmd{\indx{lpexit}}
-This command exits the current loop in the logical page list and
-prints on the next page in the list.
-
-\cmd{\indx{selectlpcounter}\int}
-This is used for changing which counter is used for specifying the
-logical page (default is 2). This macro generally should not be used
-except by people who are writing their own macros.

-\level1{Formatting a \indx{Sample Document}}
-In this section we will format a simple document
-utilizing many of the HP \TeX\ macros.
-For this example, we will accept all the HP \TeX\ default values for the
-various commands.
-\vskip.5in
-\centerline{\twelvebf A Sample Document}
-
-Isn't that nice? If we wanted to, we could have easily set that off to the
-right like this:\lbreak
-\rightline{\twelvebf A Sample Document}
-
-Now, how about \textbox{a textbox?}  Those are
-always fun. Or, if we really want to set something off, we could
-ask \TeX\ to:
-\centerbox{put it inside\cr
-           a nice little\cr
-           centered box,}
-or, maybe just \boxit{``boxit'' --  like this.}
-
-But say you're really serious about getting someone's attention.
-
-\start{warning}
-\centerline{\bf LOOK!}
-\centerline{You can use the ``Warning'' command, like we did here.}
-\finish{warning}
-
-Now, let's use the extraordinary capabilities of \TeX\ to
-generate a mathematical formula:
-$$\hat{n}_2(s)={1\over \alpha_2}\biggl[ \biggl({\partial C_2\over
-     \partial x} \biggr)_{x=0}+{k_1 \hat{n}_1\over D_1} \biggr]$$
-Next, we'll create a table to show the dimensional units available in \TeX :
-\medskip
-\tableformat{\centerline|\centerline 1in|\leftline 1.2in|\centerline 1in|%
-  \centerline .05in|\centerline 1in|\leftline 1.2in|\centerline 1in}
-\tablebar{|\span7\tbar|}
-\tablerow{|\TeX\ UNIT|DESCRIPTION|PER INCH||\TeX\ UNIT|DESCRIPTION|PER INCH|}
-\tablebar{|\span7\tbar|}
-\tablerow{|{\tt in}|inch|1||{\tt mm}|millimeter|25.4|}
-\tablerow{|{\tt cm}|centimeter|2.54||{\tt dd}|Didot point|67.54|}
-\tablerow{|{\tt pt}|printer's point|72.27||{\tt bp}|big point|72|}
-\tablerow{|{\tt pc}|pica|6.02|| | | |}
-\tablebar{|\span7\tbar|}
-\medskip
-Itemized lists are very useful:
-\itm For listing things.
-\itm For making a series of points.
-\sitm You can even use subitems.

-Now, look at the next page to see exactly how this sample
-document was formatted.
