+\head 1. Overview\endhead
+
+\AmSTeX{} is a macro package for \TeX{}, designed to simplify the input
+of mathematical material and format the output according to preset style
+specifications. Although the \AMS{} holds the copyright for \AmSTeX{},
+its use is not restricted, but is encouraged for the preparation of
+manuscripts intended for publication both in the Society's books and
+journals, and also in other mathematical literature.
+
+Version 2.0 of \AmSTeX{} was released in 1990, concurrent with the
+publication of the second edition of \JoT{}. It contained numerous
+minor improvements and bug fixes, as well as some major changes
+involving additional fonts. Version 2.1 was first released in 1991;
+interim updates are identified by changes in release date. The present
+version 2.2 was released in August 2001. This User's Guide describes all
+the new and changed features from these versions and how to use them,
+with further additions and revisions pertaining to the current release.
+Topics are grouped by type, and then presented in roughly the same order
+as they appear in \JoT{}.
+
+This User's Guide assumes that you already have a copy of \JoT{}. It
+contains references to specific sections that won't help you much if you
+don't have a copy. It also assumes for the most part that you will be
+using the ``preprint style'', a set of macros that provides features
+specific to the formatting of a document, such as headings, page
+numbers, and the like. If you are planning to use the preprint style,
+you will also need to have a copy of AMSFonts Version~2.2. \JoT{} and
+AMSFonts 2.2 are available from the \AMS{} and other distributors.
+

+
+The file \filnam{amsppt.doc} is an {\smc ascii} file, and is
+not intended to be processed with \TeX{}\null. This documentation file
+is arranged in the same order as the macro file that it describes, and
+explains the intent and mechanics of the macros in detail. A separate
+file (\filnam{amstex.doc}), documenting the file \filnam{amstex.tex},
+is available on request.
+
+In addition, other files are used during installation.
+For instructions on installing the \AmSTeX{} macros and preprint style,
+see Appendix B\null. This appendix describes the installation process
+for \TeX{} systems based on the \TeX{} Directory Structure (TDS), and

+
+\subhead General Description of Changes\endsubhead
+
+\AmSTeX{} 2.0+, the preprint style, and their technical
+documentation are the result of a joint effort begun by Michael Spivak
+and extended by the Composition Technical Support group of the \AMS{}.
+
+In version 2.0 of \AmSTeX{}, the following changes were made:
+\widestnumber\item{10}
+\roster
+\item All known bugs were eliminated.
+\item Messages were added identifying the current versions of
+ \filnam{amstex.tex} and \filnam{amsppt.sty}, to be displayed on your
+ terminal screen and in the log file.
+\item Some error and help messages were changed for the sake of
+ clarity or to provide more information.
+\item Refinements were made to conserve memory space.
+\item The CM versions of the Computer Modern fonts were substituted for the
+ older AM versions.
+\item Support for additional fonts was added.
+
+ \itemitem{(a)} \filnam{amstex.tex} provides the mechanism for accessing
+ the Euler and extra symbol fonts of the AMSFonts collection.
+ \itemitem{(b)} The preprint style assumes that fonts \filnam{msam},
+ \filnam{msbm}, and \filnam{eufm} are installed and available.
+
+\item Changes were made to the preprint style to make it conform
+ more closely to the style of AMS publications, in particular, the \JAMS.
+
+ \itemitem{(a)} Running heads were made automatic; they can be suppressed
+ if desired.
+ \itemitem{(b)} Additional elements are recognized in both the top matter
+ and the body of a document, and the input syntax was regularized.
+ \itemitem{(c)} Footnotes were changed to have normal indentation.%
+ \footnote{Like this.}
+ \itemitem{(d)} The style of the references was changed considerably.
+
+\item The ability to produce roman-numeral page numbers using the
+ plain \TeX{} convention (negative \cs{pageno}) was added.
+\item In the preprint style, mathematics-oriented hyphenation exceptions
+ were added. (These follow American, not British, rules.)
+\item An option was added in the preprint style that
+ allows documents to be formatted
+ as chapters of a monograph rather than as separate papers.
+\item Finally, some optional formatting features requested by
+ \AmSTeX{} users were added to the preprint style.
+\endroster
+
+\medskip
+In version 2.1, the following changes were made:
+\roster
+\item \cs{curraddr}, \cs{rom}, and \cs{linespacing} were added.
+\item Additional error conditions were identified and supplied with more
+ informative messages.
+\item A sporadic line-breaking problem in the preprint style references
+ section was remedied.
+\item Some bugs introduced into the preprint style during the
+ version 2.0 changes were found and eliminated.
+\item Use of the Euler fonts other than medium Euler Fraktur was
+ made more convenient.
+\item The ability to use multiple \cs{thanks} commands was added.
+\item The \cs{proclaim} font was changed from slanted to italic, and
+ \cs{proclaimfont} provided so that users can change it if desired.
+\item \cs{nologo} was reinstated.
+\item The installation instructions were revised and augmented.
+\item The backward compatibility file \filnam{amsppt1.tex} was added.
+\endroster
+
+\medskip
+These changes were made in the January 1997 release:
+\roster
+\item Bugs reported since the release of version 2.1 were fixed.
+\item \cs{urladdr} was added; \cs{linespacing} was documented.
+\item Bibliographic elements were added for {\it Math.\ Reviews},
+ {\it CMP\/} and AMS preprint server references.
+\item Various changes were made to permit easier customization:
+
+ \itemitem{(a)} Command names were given to fonts and dimensions used
+ in various environments.
+ \itemitem{(b)} Changeable end-of-document processing was split out
+ and associated with a new command name.
+ \itemitem{(c)} The output routine was simplified.
+ \itemitem{(d)} Initialization options that a user might want to
+ suppress to save space were moved into a separate file,
+ \filnam{amsppt.sti}
+
+\item Page dimensions were changed in the preprint style to match the
+ current AMS publication specifications.
+\item The mechanism for loading AMSFonts was changed to make it easier
+ for a user to specify the use of a PostScript outline version.
+\item The installation instructions were updated and augmented.
+\endroster
+
+These changes were made in version 2.2:
+\roster
+\item Bugs reported since the release of version 2.1 were fixed.
+\item The requirement to acknowledge use of \AmSTeX{} was removed, and
+ the copyright statement and restriction notice is no longer printed
+ out on the terminal every time \AmSTeX{} starts up.
+\item The installation instructions were completely revised, and based
+ on the \TeX{} Directory Structure (TDS) used by most current \TeX{}
+ distributions.
+\item a \cs{subjclassyear} command was provided to allow a particular
+ version of the Mathematics Subject Classification to be cited.
+\endroster
+
+\subhead This User's Guide\endsubhead
+
+This User's Guide has been prepared using \AmSTeX{} Version~2.2 with the
+preprint style. Some changes have been made: font and dimension settings
+have been reset, the macros for headings have been redefined to produce a
+result more suited to documentation, and some {\it ad hoc\/} macros have
+been defined to simplify the presentation of particular information.
+However, in general, this document and the file from which it was produced
+illustrate the general appearance and input for a preprint with running
+heads. Printing the output of \TeX{} for this Guide requires AMSFonts
+Version~2.0 or later
+(users of AMSFonts Version~2.0 are strongly encouraged to upgrade to
+Version~2.2).
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\head 2. Formatting Features
+\endhead
+
+Formatting documents prepared with \AmSTeX{} is accomplished by a
+``style file''. The features described here are part of the preprint
+style. The \AmSTeX{} preprint style, Version~2.2, will format an input
+file in a manner suitable for a paper in a journal, unless the style of
+a \cs{Monograph} is explicitly selected. Unless noted otherwise,
+the journal style is the style described below.
+
+\setbox1=\hbox{\tt\\dedicatory...\\enddedicatory\ }
+\setbox0=\vbox{\hsize=\wd1\parindent=0pt\tt\obeylines
+ \strut\\title...\\endtitle
+ \\author...\\endauthor
+ \\affil...\\endaffil
+ \\address...\\endaddress
+ \\curraddr...\\endcurraddr
+ \\email...\\endemail

+\setbox1=\hbox{$\dsize\left\lbrace\,\vcenter{\vphantom{\copy0}}\right.
+ \nulldelimiterspace=0pt$}%
+\setbox2=\hbox{\kern-\wd1$\dsize\left\lbrace\,\vcenter{\copy0}\right\rbrace$}
+
+\subhead Top Matter\endsubhead
+
+Some commands affect the appearance of a whole document. Such commands
+should go at the top of your input file, right after the \cs{documentstyle}
+line and before the \cs{topmatter} line. This area will be referred to as
+the ``preamble''. Commands that should be in the preamble include
+\cs{define}, \cs{TagsOnRight} and the like,
+\cs{NoPageNumbers}, \cs{NoRunningHeads}, \cs{Monograph},
+\cs{pagewidth}, \cs{pageheight}, \cs{pageno},
+and commands that load fonts.
+The preamble is relevant to any document, whether paper or monograph.
+
+The beginning of an \AmSTeX{} file should look something like what
+is shown in Figure 1.
+
+\topinsert
+
+\beginexample{}
+\\input amstex
+\\documentstyle\{...\}
+\medskip
+\<preamble commands, such as \cs{define}, \cs{pageno}, \cs{Monograph},
+\leavevmode\hbox to20pt{}\cs{NoRunningHeads}, \cs{loadbold}, etc.>
+\medskip
+\\topmatter
+\indent\box2
+\strut\\endtopmatter
+\\document
+\endexample
+
+\botcaption {Figure 1} The beginning of an \AmSTeX{} file
+\endcaption
+\endinsert
+
+If any \cs{end...}\ tag is omitted (or misspelled), an error message will
+appear at \cs{endtopmatter} or at the next blank line: for example, if
+you misspell \cs{endtitle}, the message will be something like
+``{\tt !~Paragraph ended before \cs{title} was
+com\discretionary{-}{}{}plete}.'' If you omit \cs{endtopmatter}, there
+won't be any error message, but none of the topmatter material will
+print. %{\tolerance2000\par}
+Tags should be omitted for any top matter elements for which there is
+no data; if ``empty'' tags are included, empty footnotes may appear on
+the first page, or labels indicating addresses at the end of a paper.
+
+If you have documents that were prepared for versions of \AmSTeX{}
+earlier than version 2.0, you may find the file \filnam{amsppt1.tex}
+useful. By including the line \cs{input amsppt1} immediately after the
+\cs{documentstyle} line, the topmatter commands and the sectioning
+commands that changed in form will work in the original way. Other than
+that, there should be few incompatibility problems with previous
+versions. Note: The use of \filnam{amsppt1.tex} is discouraged except
+for processing preexisting files.
+
+For multi-line titles, affiliations, authors, or dedications (basically
+everywhere that lines are centered individually rather than being set in
+paragraphs), line breaks are obtained by using \cs{\\}. In other parts
+of the topmatter, which are set in paragraph form, line breaks are
+obtained by \cs{linebreak}.
+
+The title will be set in uppercase. To turn off the automatic
+uppercasing, use the \cs{nofrills} option:
+\cs{title\\nofrills...\\endtitle}.
+
+Each author is tagged separately, followed by address(es) and other
+information associated with that author.
+
+Normally, the address given with \cs{address} is the address of the
+author at the time the research was being done; if the author's
+address at the time of publication is different, the current address
+should be given with \cs{curraddr}. This should be entered immediately
+following the \cs{address} for the same author. If a \cs{curraddr} is
+not paired with an \cs{address}, the current address will not print.
+
+Electronic mail addresses can be tagged \cs{email...\\endemail}.
+Like \cs{curraddr}, every \cs{email} address must be paired with a regular
+\cs{address}, otherwise the e-mail address will not print.
+The \cs{email} address will be printed at the end of the paper, as
+``{\it E-mail address:\/} \<net-address>'', following the address (and
+current address, if present) with which it is paired.
+
+URLs, the addresses of ``home pages'' on the World Wide Web, can be
+included using \cs{urladdr...\\endurladdr}. They behave in the same
+manner as \cs{email} addresses.
+
+The \cs{thanks} command is provided for acknowledgments of grant support
+and other kinds of support for the author's research, or other general
+information not covered by one of the predefined tags such as
+\cs{keywords} or \cs{subjclass}. The information will be printed as an
+unnumbered footnote at the bottom of the first page. Like \cs{address},
+\cs{thanks} can be used more than once, and is associated with a
+particular author.
+
+In case a paper has not only an author but a translator, \cs{translator}
+is provided. This information will be printed at the end of the paper in
+eight-point roman, as ``Translated by'' followed by the translator's name
+in uppercase.
+
+The \cs{dedicatory} command is used for such things as
+``Dedicated to Professor X on the occasion of his eightieth birthday.''
+The dedication will appear in italics, before the abstract.
+
+The information for \cs{keywords} and \cs{subjclass} appears as
+unnumbered footnotes at the foot of the first page, as in AMS journals.
+In a monograph chapter they will not print at all, since they should be
+handled separately, as part of the front matter for the monograph.
+By default, for backward compatibility, the 1991 Mathematics Subject
+Classification will be cited; to specify the 2000 Mathematics Subject
+Classification, enter
+\beginexample{}
+\\subjclassyear\{2000\}
+\\subjclass ...\\endsubjclass
+\endexample
+
+The abstract heading ``{\eightpoint\smc Abstract.}''\ appears in caps
+and small caps, in the same size (eight point) as the abstract itself.
+
+A simple table of contents setup is available. Tables of contents
+are typed in the topmatter along with everything else (except for
+monographs---see the section {\bf Book Formatting} below), using
+\cs{toc...\\endtoc}.
+\beginexample{}
+\\toc
+\\specialhead...\\endspecialhead
+\\head...\\endhead
+\\subhead...\\endsubhead
+\\subsubhead...\\endsubsubhead
+\\endtoc
+\endexample
+\noindent
+The syntax of the parts is identical to the syntax used
+for headings within the document (see the sections {\bf Headings} and
+{\bf Book Formatting} below), so that for those who wish to do so
+and have a capable text editor, the table of contents can be constructed
+by extracting the relevant lines from the main text.\footnote{But note that
+the original line breaks in multi-line headings would not be appropriate
+for the table of contents, so you'd want to remove any \cs{\\}es that
+might be present.}
+
+Page numbers aren't usually appropriate for the short table of contents
+that might appear in a journal article, but if desired, page numbers can
+be entered in a manner similar to that for a monograph; see the section
+{\bf Book Formatting} below.
+
+The hanging indentation within a table of contents for \cs{head} and
+\cs{subhead} is preset to accommodate numbers of the form
+``1.''\ and ``1.1.''\ respectively; the amount of indentation can
+be adjusted by using \cs{widestnumber}:
+\beginexample{}
+\\toc
+\\widestnumber\\head\{10\}
+\\widestnumber\\subhead\{10.1\}
+...
+\endexample
+\noindent This can be done more than once within different sections of
+the table of contents, if desired.
+
+If the ``section number'' of a \cs{head} happens to be something like
+``Appendix'' (as actually happens in this User's Guide), a pair
+of empty braces should be entered before it, as follows:
+\beginexample{}
+\\head \{\}\ Appendix. Sample bibliography input ...\\endhead
+\endexample
+\noindent
+Insertion of {\tt\{\}} followed by a space at the beginning of the heading
+text will cause the entire entry to be set flush left as a unit.
+
+If you are preparing a monograph, the format and content of the top matter
+will be different. See the section below on {\bf Book Formatting} for
+details.
+
+
+\subhead Headings \endsubhead
+
+There are four levels of headings (not counting
+\cs{title}):
+\beginexample{}
+\\specialhead...\\endspecialhead
+\\head...\\endhead
+\\subhead...\\endsubhead
+\\subsubhead...\\endsubsubhead
+\endexample
+\noindent The heading of
+this section was typed as
+\beginexample{}
+\\head 2. Formatting Features
+\\endhead
+\endexample
+
+\noindent And the subheading for this subsection was typed as
+\beginexample{}
+\\subhead Headings\\endsubhead
+\endexample
+\noindent
+Ordinarily, subheadings in the preprint style are run into the text, but for
+this User's Guide, the style varies slightly.
+
+\indent\cs{specialhead} is for long articles that need extra divisions at
+a level above the \cs{head} level. In the preprint style
+\cs{specialhead} uses boldface type and is set ragged right; \cs{head}
+is small caps, centered; \cs{subhead} is boldface, flush left,
+run in with the following text; and
+\cs{subsubhead} is italic, indented as for an ordinary paragraph, and run
+into the text.
+
+Explicit line breaks are obtained by a \cs{\\} in a \cs{head} or a
+\cs{specialhead}, but for \cs{subhead} and \cs{subsubhead},
+which are part of their paragraph, just use \cs{linebreak} as
+you would in normal paragraphed text.
+
+If you are preparing a monograph, the styles of headings will be different.
+See the section below on {\bf Book Formatting} for details.
+
+
+\subhead Theorems and Proofs \endsubhead
+
+In addition to the usual proclamations and demonstrations, mathematicians
+may pose other kinds of propositions, which editors may prefer to see
+presented in different styles. The following have been provided in
+the preprint style.
+\beginexample{}
+\\definition...\\enddefinition
+\\example...\\endexample
+\\remark...\\endremark
+\endexample
+\noindent
+The proof of any proclamation is indicated by \cs{demo...}\cs{enddemo}.
+
+Note that all kinds of proclamations, demonstrations and propositions
+must be ended explicitly; a check for proper endings is included with
+all classes of proclamations and a missing \cs{end...} is reported.
+
+In the preprint style \cs{definition} and \cs{example} have
+the spacing and heading font of \cs{proclaim}, but are in roman.
+\cs{remark} resembles \cs{demo}
+except that extra space added at the end of a proof by \cs{enddemo}
+is not added by \cs{endremark}.
+
+In accordance with the style of the \JAMS, the labels on \cs{proclaim}s
+and similar constructions are now printed in boldface type (\cs{bf})
+and the text in italic (\cs{it}). (The command \cs{proclaimfont} is
+provided so that a user can change the text of a proclamation to
+slanted type if desired: \cs{redefine\\proclaimfont\{\\sl\}}.)
+
+It is conventional in mathematical publishing to use roman, upright
+numbers and punctuation even in the midst of
+italic text, to avoid visual conflicts with numbers and punctuation in
+adjacent math formulas. Since dedicated ``mathematical text italic''
+fonts containing roman numbers and punctuation are not currently
+available, the \filnam{amsppt} preprint style provides a command
+\cs{rom} to be applied inside theorems and other stretches of
+italic text, to give the desired results.
+For example, to~produce
+
+\proclaim{Proposition 2.5} Let $S_1,\dots,S_m$ be the components
+of a $J$-holomorphic cusp-curve $S$ and suppose that each
+component $S_i$ is \rom(a multiple covering of\rom) a regular
+curve and that Assumption \rom{(1.4a)} is satisfied. \dots
+\endproclaim
+
+\noindent you would use \cs{rom} in the following places:
+\beginexample{}
+each component \$S\char`\_i\$ is \\rom(a multiple covering of\\rom) a
+regular curve and that Assumption \\rom\{(1.4a)\} is satisfied
+\endexample
+
+As you can see, \cs{rom} is used like the math font command \cs{roman}:
+it applies to the next single character or the next group enclosed in
+braces.
+
+\subhead Other Devices \endsubhead
+
+For a list produced by \cs{roster}, the amount of indentation can be
+adjusted to accommodate wide item numbers. Just before beginning the
+\cs{roster}, type, for example, \cs{widestnumber\\item\{(viii)\}}.
+This adjustment is temporary. The default will be reinstated by
+\cs{endroster}.
+
+The command \cs{cite} produces
+a reference citation in roman type, within square brackets: \cite{21}.
+
+A structure \cs{block...}\cs{endblock} is provided for quotations.
+It is intended for use in the middle of a paragraph to quote an
+extract from another source.
+
+
+\subhead Book Formatting \endsubhead
+
+If you are preparing a monograph, several features are available in the
+preprint style that will make your output look like chapters rather than
+individual papers.
+
+First of all, you must signal your intentions by typing \cs{Monograph}
+in the preamble, right after the \cs{documentstyle} line.
+
+A typical topmatter section for a monograph chapter would be typed
+like this:
+\beginexample{}
+\\documentstyle\{amsppt\}
+\\Monograph
+\\topmatter
+\\title\\chapter\{4\} Matrix Algebras\\endtitle
+\\endtopmatter
+\endexample
+\noindent which produces a chapter heading that looks like this:
+\bigskip
+\vbox{
+\centerline{\eightpoint CHAPTER IV}
+\bigskip
+\centerline{\bf MATRIX ALGEBRAS}}
+\bigskip
+\noindent
+Notice that the number is converted automatically to roman numerals and
+the word ``{\eightpoint CHAPTER}'' is added. For a chapter title that
+needs a different sort of treatment, \cs{nofrills} can be used:
+
+\beginexample{}
+\\topmatter
+\\title\\chapter\\nofrills\{APPENDIX D\} The Poisson Integral\\endtitle
+\\endtopmatter
+\endexample
+\noindent This produces
+\bigskip
+\vbox{
+\centerline{\eightpoint APPENDIX D}
+\bigskip
+\centerline{\bf THE POISSON INTEGRAL}}
+\bigskip
+\noindent The replacement \cs{chapter} text will appear exactly as
+typed.
+
+Finally, for things like a preface or introduction which have no
+pretitle text at all, omit the \cs{chapter} command:
+\beginexample{}
+\\topmatter
+\\title Preface\\endtitle
+\\endtopmatter
+\endexample
+
+In monographs, the table of contents is usually treated as a separate
+chapter. Start by typing the title ``Contents'' as for a preface or
+introduction, and then use the \cs{toc...\\endtoc} structure as the
+body of the document (rather than putting it in the topmatter, as you
+would for a journal article).
+\beginexample{}
+\\topmatter
+\\title Contents\\endtitle
+\\endtopmatter
+\bigskip
+\\document
+\\toc
+\\title Preface\\page\{vii\}\\endtitle
+\\title\\chapter\{1\} Matrix Algebras\\page\{1\}\\endtitle
+\\head \{\} Continuous complex-valued functions\\page\{1\}\\endhead
+...
+\\title Bibliography\\page\{307\}\\endtitle
+\\endtoc
+\\enddocument
+\endexample
+
+The chapter titles listed in the table of contents are typed in the same
+way as in actual use. To get page numbers in the table of contents, use
+\cs{page} as shown, just before the ending of an element. This option
+is available for all levels of headings.
+
+In a monograph using the preprint style, the chapter title is used for
+the left running head and the text of section headings
+(from \cs{head}) appears as the right running head.
+It's not uncommon for the text of a heading to be too long to fit
+in the running head width; in such a case use \cs{rightheadtext} to
+specify a shortened form of the heading for use in the running heads:
+\beginexample{}
+\\head Fourier coefficients of continuous periodic functions
+of bounded entropy norm\\endhead
+\\rightheadtext\{Fourier coefficients of periodic functions\}
+\endexample
+\noindent This should follow immediately after the \cs{head}, to ensure
+that both take effect on the same page. If the chapter title is too long
+to fit as a running head, a shortened form can be supplied in a similar
+way with \cs{leftheadtext} immediately after the \cs{title}.
+See also the section~{\bf Running Heads}.
+
+The style for a chapter of a monograph differs in some particulars from the
+style for a paper. The text of a \cs{head} will be boldface instead of
+small caps; headings of theorems, propositions, definitions, remarks, etc\.
+will be small caps instead of boldface, and indented rather than flush
+left.
+
+
+\subhead Inserts with Captions \endsubhead
+
+Figures, tables, and some other kinds of objects are often handled as
+inserts. These objects may be prepared separately from the main document
+and pasted in, in which case space must be left for them.
+These objects usually have captions; a caption may be positioned above (for
+a table) or below (for a figure).
+
+An insert may be specified for the top or ``middle'' of a page, i.e.,
+right where the input for the insert occurs in the text. These are
+typed as \cs{topinsert} and \cs{midinsert} respectively.
+Furthermore, a caption may be placed at the top or the bottom of the insert,
+using the tags \cs{topcaption} and \cs{botcaption} respectively.
+
+The general structure used to specify an insert with a caption at the top is:
+\beginexample{}
+\\topinsert\quad{\rm or}\quad \\midinsert
+\cs{captionwidth}\{\Dimen\}\quad{\rm(optional)}
+\\topcaption\{\<caption label>\}
+\ \<optional caption text>
+\\endcaption
+\cs{vspace}\{\Dimen\}\quad{\rm or}\quad%
+ \<optional code for the insertion body>
+\\endinsert
+\endexample
+
+Here the notation \Dimen{} means a valid \TeX{} dimension as
+described in the {\bf Dimensions} section of \JoT{}.
+If a bottom caption was desired, \cs{topcaption} would be replaced by
+\cs{botcaption}, and
+the \cs{vspace} command (or the
+optional code for the insertion body) would be moved before the
+\cs{botcaption} macro.
+
+The \cs{vspace\{\Dimen\}} option would be used to leave blank space for
+an object to be pasted into place. The value of the \Dimen{} should be
+the exact height of the object to be pasted in, because extra space
+around the object and the caption are dependent on the document style,
+and will be provided automatically.
+
+The \cs{captionwidth\{\Dimen\}} option may be used to override the default
+caption width specified by the document style.
+
+The \<caption label> is something like ``Figure~1'' or ``Table~2a''.
+Do not type any final punctuation; it will be provided. The caption
+label will be set in caps and small caps.
+
+The \<optional caption text> is any descriptive text that may be desired.
+The preprint style will set this in roman. Even if there is no text, the
+\cs{endcaption} tag must be present.
+
+If you choose to include the \TeX{} code for a figure, table, or other
+captioned object in the input, then omit the \cs{vspace} command
+and type the code where appropriate (before \cs{botcaption}
+or after the \cs{endcaption} of \cs{topcaption}).
+
+Sometimes a table is small enough that it is not necessary to put it in an
+insert. If the caption is to appear above it, input can be typed as follows:
+\beginexample{}
+\\topcaption\{\<caption label>\}
+\ \<optional caption text>
+\\endcaption
+\ \<code for the table body>
+\endexample
+\noindent
+The form of the input would be the following if the caption is to appear below:
+\beginexample{}
+\ \<code for the table body>
+\\botcaption\{\<caption label>\}
+\ \<optional caption text>
+\\endcaption
+\endexample
+\noindent
+To avoid page-breaking problems,
+this form of ``insertion'' should be used only for very small objects.
+
+
+\subhead Page Numbers \endsubhead
+
+If you are using the preprint style, page numbers will appear in the running
+heads, at the outside margin, except for the first page, where the running head
+will be omitted and the page number will be centered at the bottom of the page.
+
+If you wish to omit page numbers, type \cs{NoPageNumbers} in the preamble
+of the document (after the \cs{documentstyle} line).
+The running head text will remain; see also {\bf Running Heads}.
+
+You can get roman numeral page numbers, e.g.\ for a table of contents or
+preface, using the normal \TeX{} convention of \cs{pageno} plus
+a negative number.
+
+
+\subhead Page Size and Line Spacing \endsubhead
+
+In the preprint style, the default page width is 30pc, and the default
+height is 50.5pc.
+You can change the size of the page by typing
+\beginexample{}
+\\pagewidth\{\Dimen\}\newline
+\\pageheight\{\Dimen\}
+\endexample
+\noindent using suitable \Dimen{}s, where by this notation we mean a
+valid \TeX{} dimension as described in the {\bf Dimensions} section of
+\JoT{}.
+
+The spacing between lines in the preprint style is ordinarily 2pt greater
+than the nominal type size. This can be changed by providing a multiplication
+factor to the command \cs{linespacing}; for example, \cs{linespacing\{1.5\}}
+gives the effect of typewritten doublespacing.
+
+
+\subhead QED \endsubhead
+
+In the preprint style, \cs{qed} gives an open box `$\square$',
+separated from what precedes it by a quad of space.
+
+
+\subhead Running Heads \endsubhead
+
+If you are using the preprint style, running heads similar to those in
+\Joy{} will appear, with text in the center and page numbers to the
+outside. (On the first page, as usual, the running head is omitted, and
+the page number is placed at the bottom.)
+
+If you do nothing to define the text of the running heads, the author's
+name will be used on the left-hand and the title on the right-hand pages.
+(This is the style for papers; for monographs, see below.)
+If you want some other values, say a shortened title, you
+can redefine the text to appear on left- and right-hand pages by typing
+\beginexample{}
+\\leftheadtext\{\<left running head text>\}
+\\rightheadtext\{\<right running head text>\}
+\endexample
+
+\noindent These instructions can appear anywhere after the
+\cs{documentstyle} command, but the most
+common place to use them is immediately after a \cs{title} or
+\cs{author} or \cs{head} to override the automatic running head text.
+If \cs{rightheadtext} or \cs{leftheadtext} is specified above the
+topmatter, \cs{title} and \cs{author} will not override them.
+
+If you are doing a monograph rather than a journal article, and use
+the \cs{Monograph} switch, it affects the running heads as follows:
+The chapter title appears in the left-hand running heads, and the text of
+the current section heading (from \cs{head}) appears in the right-hand
+running heads. In chapters that don't contain any \cs{head}s---for
+example, a foreword---both the left- and right-hand running heads
+will contain the chapter title.
+
+By default, running heads will be uppercase. This is a frill that
+can be turned off by \cs{nofrills}, e.g.,
+\beginexample{}
+\\rightheadtext\\nofrills\{Text of Running Head\}
+\endexample
+
+If for some reason you don't want running heads at all, type
+\cs{NoRunningHeads} in the preamble of the document (after the
+\cs{documentstyle} line). When running heads are omitted, page numbers
+will appear centered at the bottom of the page. (And even those can be
+turned off using \cs{NoPageNumbers}.)
+
+In a monograph, if you don't want
+the text from the section \cs{head}s to appear in the running heads
+you must redefine the internal command, \cs{headmark}, that is used
+by \cs{head} to set the right-hand running head. To do this, put the
+following line in your document file, after \cs{Monograph} and
+before \cs{topmatter}:
+\beginexample{}
+\\redefine\\headmark\#1\{\}
+\endexample
+\noindent (where the {\tt\#1} is an argument number as explained in \Joy,
+in the description of \cs{define} and related commands).
+
+\subhead Tables \endsubhead
+
+There are no special macros to support the creation of tables in
+\AmSTeX{}. Plain \TeX{}'s \cs{settabs}
+command and \cs{halign} can also be used (see {\it The \TeX{}book} for
+documentation of their usage). More sophisticated table macro packages
+are available from other sources. See also the section {\bf Inserts with
+Captions} above.
+
+\subhead Bibliographies \endsubhead
+
+The references section of a paper begins with \cs{Refs} and must have
+\cs{endRefs} at the end. Each entry in the references begins with
+\cs{ref} and ends with \cs{endref}. The individual elements between
+\cs{ref} and \cs{endref} can be specified in any order. However,
+following \cs{ref} is usually a number or other label identifying the
+particular reference. This label is produced using \cs{key}.
+The format of the labels is determined by the current
+{\it references style}, which is set by the \cs{refstyle}
+command. The preprint document style provides three reference
+styles denoted A, B, and C, corresponding to
+letter labels, no labels, and arabic numbers respectively.
+The form of the \cs{cite} and \cs{key} commands for each
+style, and the output they produce, is as follows:
+$$
+\vbox{\offinterlineskip\def\strut{\vrule depth.35\normalbaselineskip
+ width0pt height.75\normalbaselineskip}\tabskip0pt
+ \halign{{\tt\strut#}\hfil&\quad#\hfil&\quad\vrule\quad{\tt#}\hfil&
+ \quad#\hfil&\quad\vrule\quad{\tt#}\hfil&\quad#\hfil\cr
+\multispan2\strut depth.7\normalbaselineskip\cs{refstyle\{A\}}&
+ \multispan2\quad\vrule\quad\cs{refstyle\{B\}}&
+ \multispan2\quad\vrule\quad\cs{refstyle\{C\}}\cr
+%
+\noalign{\hrule}
+%
+ height1.1\normalbaselineskip\cs{cite\{DK\}}& [DK]&
+ \cs{cite\{Smith 1989\}}& [Smith 1989]&
+ \cs{cite\{19\}}& [19]\cr
+%
+\cs{key DK}& [DK]&
+ \omit\quad\vrule\quad(no key)\hfil & (no label)&
+ \cs{key 19}& 19.\cr
+}}$$
+The \cs{refstyle} command is normally placed in the preamble of
+a document.
+
+The references are set with hanging indentation. The amount of indentation
+is preset to accommodate the most common case, two-digit numbers.
+It can be increased (or decreased) by specifying the widest
+label used in the references. For example,
+\beginexample{}
+\\widestnumber\\key\{GHMR\} \% refstyle A
+\\widestnumber\\key\{999\} \% refstyle C --- 3 digits
+\endexample
+\noindent
+will increase the indentation to accommodate the key \hbox{[GHMR]}, or a
+three-digit number, respectively. You could also specify
+\cs{widestnumber}\cs{key\{9\}} to reduce the indentation from two digits'
+worth to one, if your bibliography has fewer than ten entries. As the
+examples show, you do not include square brackets, periods, font
+commands, or other such formatting when using \cs{widestnumber}. The
+indentation will be adjusted for these things automatically.
+
+For consecutive references by the same author(s), \cs{by} is used for
+the first reference, with the author name(s) given in full, and
+\cs{bysame} is used for subsequent ones---just the command \cs{bysame}
+without repetition of the name(s). The horizontal line produced by
+\cs{bysame} has a fixed length of three ems.
+
+Two variations, \cs{ed} and \cs{eds}, are provided for entering editor
+names, as with \cs{page} and \cs{pages}, because the note ``ed.''\ or
+``eds.''\ is part of the automatic formatting. If \cs{by} is absent,
+the editor name(s) will be used in place of the author name.
+
+For a proceedings volume, the place and date of the meeting can
+be recorded in the \cs{procinfo} field. Parentheses will be
+added.
+
+There are two options for miscellaneous notes at the end of a reference,
+\cs{finalinfo} and \cs{miscnote}. \cs{miscnote} differs only by
+automatically adding parentheses; it would typically be used for
+a note such as ``(preprint)'' or ``(submitted)'' or ``(to appear)''.
+Because it's fairly common, the latter has its own command \cs{toappear}
+that is equivalent to \cs{miscnote} {\tt to appear}.
+
+\cs{lang} is used to indicate the original language for papers where
+bibliographic information has been translated or there is some other reason
+to believe that the original language cannot be correctly identified from
+information in the reference.
+
+Sometimes several references are combined into one---for example, parts
+of a long paper that have been published separately. Another type of
+compound reference is a work cited both in the original and in
+translation. There are commands \cs{moreref} and \cs{transl} to handle
+such situations. After \cs{moreref} and \cs{transl}, any of the normal
+reference tags can be used again.
+
+\cs{moreref} is used for citing, e.g., ``part II'' of an article; the
+\cs{moreref} command is followed by the desired additional tags and
+data. For example:
+\beginexample{}
+...\\moreref\\paper\\rom\{II\}
+\\jour Comm. Pure Appl. Math. \\vol 36
+\\yr 1983 \\pages 571--594\\endref
+\endexample
+
+When using \cs{transl}, a note that describes the translation is
+normally entered between \cs{transl} and the next tag. The tags and data
+for the translated work then follow. For example:
+\beginexample{}
+...\\transl English transl. \\publ Birkh\\"auser
+\\publaddr Basel \\yr 1985 \\endref
+\endexample
+
+Automatic punctuation will be omitted if the pertinent field was
+included but left blank. Otherwise, the command \cs{nofrills} can be
+used to keep automatic punctuation from appearing. For example,
+\cs{bookinfo\\nofrills...}\ suppresses the comma or other punctuation
+that would normally be added at the end of the \cs{bookinfo}
+information. \cs{nofrills} also suppresses other automatic formatting
+such as the word ``eds.''\ for \cs{eds}, the word ``vol.''\ for book volumes,
+or the parentheses around the year for journal articles. The ending
+period of a reference can be suppressed with
+\cs{finalinfo}\cs{nofrills}.
+
+Some examples will illustrate the use of these tags. See Appendix~A for
+samples of input and output. See also Appendix~C of \JoT{} (first
+edition: Appendix~B) for more information on references.

+\subhead Wide Accents in Math Mode \endsubhead
+
+In version 2.0+ of the AMSFonts,
+there are wider versions of the \cs{widehat} and \cs{widetilde}
+accents; they appear on lines (5) and (6):
+\beginexample{}
+\exbox{(1)}{\$\\hat x, \\tilde x\$} $\hat x, \tilde x$
+\exbox{(2)}{\$\\widehat x, \\widetilde x\$} $\widehat x, \widetilde x$
+\exbox{(3)}{\$\\widehat\{xy\}, \\widetilde\{xy\}\$} %

+\endexample
+\noindent
+These wider accents are in the \filnam{msbm} family. If \filnam{msbm}
+has been loaded, \cs{widehat} and \cs{widetilde} will automatically
+select these wider versions when required; otherwise, the characters

+A number of fonts were created for use with \AmSTeX{} 2.0+, both
+Computer Modern fonts in sizes not previously available and new fonts

+These fonts are in the collection AMSFonts Version~2.2. They must be

+\subsubhead Considerations and warnings\endsubsubhead
+The commands to load these font files should be typed in the preamble area
+between the
+\cs{documentstyle\{...\}} line and the \cs{topmatter}.
+Each \cs{load...} command loads the pertinent fonts (including
+subscript sizes), assigns a ``math
+family'' for them, and defines a math font command.
+The names of the commands are the same as the font names:
+\cs{eufm}, \cs{eufb}, \cs{eusm}, \cs{eusb}, \cs{eurm}, and
+\cs{eurb}. These are used in the same way as
+\cs{roman} or \cs{bold}, e.g., \cs{eufb\{M\}} or \cs{eufb M}@.
+\AmSTeX{} also defines a couple of synonyms,
+\cs{frak} and \cs{goth}, for \cs{eufm} (medium Euler Fraktur).
+
+\TeX{} can accommodate only sixteen font families in math mode; eight
+are already defined by plain \TeX{} before \AmSTeX{} begins, and the
+preprint style loads three more (\filnam{msam}, \filnam{msbm}, and
+\filnam{eufm}), for a total of eleven. For this reason, you should load
+additional fonts with care, requesting only those you know for certain
+you will need.
+
+All the fonts described here, and some others as well, are included in the
+collection AMSFonts Version~2.2, which is available from the AMS and other
+distributors. The math fonts mentioned here are all supplied in sizes from
+five through ten point, suitable for use in mathematical text.
+
+If you intend to use the AMSFonts in PostScript Type~1 outline form,
+see Appendix C.
+
+
+\subhead Bold Characters in Math Mode \endsubhead
+
+Bold letters are obtained by \cs{bold} as described in \Joy{}.
+In addition, bold symbols, italic, and lowercase Greek can be
+obtained once \cs{loadbold} appears in the file (this
+requires version 2.0+ of \AmSTeX{} and AMSFonts). Two control sequences
+are used for different kinds of bold symbols:
+\beginexample{\exboxwidth=1.25in}
+\exbox{}{\\boldkey} for symbols that actually appear on the keyboard
+\exbox{}{\\boldsymbol} for symbols specified by a single control sequence
+\endexample
+\noindent
+For example,
+$$\hbox{\tt\$\\bold x \\boldsymbol\\in \\boldsymbol\\varGamma\$}$$
+gives
+$$\bold x \boldsymbol\in \boldsymbol\varGamma$$
+[and {\tt\$\\boldsymbol\\lbrack a \\boldsymbol\\rbrack\$} gives
+$\boldsymbol\lbrack a \boldsymbol\rbrack$, if you need to use
+\cs{lbrack} and \cs{rbrack} instead of the {\tt[} and {\tt]} keys].
+
+More precisely, \cs{boldkey} can be used in math formulas in the
+following combinations:
+\roster
+\item"$\bullet$" With any of the symbols
+$$ +\ \ -\ \ =\ \ <\ \ >\ \ (\ \ )\ \ [\ \ ]\ \ |\ \ /\ \ *
+ \ \ .\ \ ,\ \ :\ \ ;\ \ !\ \ ?$$
+to give
+$$
+\boldkey+\ \ \boldkey-\ \ \boldkey=\ \ \boldkey<\ \ \boldkey>\ \
+\boldkey(\ \ \boldkey)\ \ \boldkey[\ \ \boldkey]\ \ \boldkey|\ \
+\boldkey/\ \ \boldkey*\ \ \boldkey.\ \ \boldkey,\ \ \boldkey:\ \
+\boldkey;\ \ \boldkey!\ \ \boldkey?
+$$
+But \cs{bold} cannot be used to get bold versions of these symbols.
+{\tt\$\\bold+\$} will give only the ordinary $+$, etc.
+
+The bold $\boldkey+$ and $\boldkey-$ will be binary operators,
+like the ordinary $+$ and $-$ symbols;
+the bold $\boldkey=$ will be a binary relation, like the ordinary $=$, etc.
+
+\medskip
+\item"$\bullet$" With letters:
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\boldkey a\$, ..., \$\\boldkey z\$} %
+ $\boldkey a, \dots, \boldkey z$
+\exbox{}{\$\\boldkey A\$, ..., \$\\boldkey Z\$} %
+ $\boldkey A, \dots, \boldkey Z$
+\endexample
+\noindent
+Notice that these are $\fam\cmmibfam bold\ math\ italic$ letters, as
+opposed to the bold text letters $\bold a, \dots, \bold z$, $\bold A,
+\dots, \bold Z$ that you get by using \cs{bold} in math mode.
+
+\medskip
+\item"$\bullet$" With numerals:
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\boldkey 0\$, ..., \$\\boldkey 9\$} %
+ $\boldkey 0, \dots, \boldkey 9$
+\endexample
+\noindent
+However, these combinations simply give the same numerals that you get with
+{\tt\$\\bold0\$}, \dots, {\tt\$\\bold9\$}.
+\endroster
+
+\medskip
+The \cs{boldsymbol} construction can be used in any of the following
+combinations:
+\roster
+\item"$\bullet$" With uppercase and lowercase Greek letters
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\boldsymbol\\Gamma\$, ..., \$\\boldsymbol\\Omega\$} %
+ $\boldsymbol\Gamma$, \dots, $\boldsymbol\Omega$
+\exbox{}{\$\\boldsymbol\\varGamma\$, ..., \$\\boldsymbol\\varOmega\$} %
+ $\boldsymbol\varGamma$, \dots, $\boldsymbol\varOmega$
+\exbox{}{\$\\boldsymbol\\alpha\$, ..., \$\\boldsymbol\\omega\$} %
+ $\boldsymbol\alpha$, \dots, $\boldsymbol\omega$
+\endexample
+\noindent
+In versions of \AmSTeX{} earlier than 2.0, bold unslanted uppercase
+Greek letters $\boldsymbol\Gamma$, \dots, $\boldsymbol\Omega$ were
+specified by \cs{boldGamma}, \dots, \cs{boldOmega}; these control
+sequences have now disappeared.
+
+\medskip
+\item"$\bullet$"
+For convenience, \cs{boldsymbol} may also be followed by a letter (but
+not by a numeral or other character), giving the same result as
+\cs{boldkey}.
+
+\medskip
+\item"$\bullet$"
+You can also apply \cs{boldsymbol} to all the other standard symbols that
+are specified by single control sequences. For example, to get bold primes:
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\boldsymbol\\prime\$} $\boldsymbol\prime$
+\exbox{}{\$\\boldsymbol A\^{ }\{\\boldsymbol\\prime\}\$} %
+ $\boldsymbol A^{\boldsymbol\prime}$
+\endexample
+\noindent
+(But \cs{boldsymbol'}, using the shorthand notation for \cs{prime},
+won't work.)
+
+\medskip
+\item"$\bullet$"
+You can apply \cs{boldsymbol} to ``delimiters'', such as
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\boldsymbol\\\{ ... \\boldsymbol\\\}\$} %
+ $\boldsymbol\{ \dots \boldsymbol\}$
+\exbox{}{\$\\boldsymbol\\langle ... \\boldsymbol\\rangle\$} %
+ $\boldsymbol\langle \dots \boldsymbol\rangle$
+\exbox{}{\$\char`\|, \\boldkey\char`\|, \\\char`\|, \\boldsymbol\\\char`\|\$} %
+ $|,\ \boldkey|,\ \|,\ \boldsymbol\|$
+\exbox{}{\$\\vert, \\boldsymbol\\vert, \\Vert, \\boldsymbol\\Vert\$} %
+ $\vert,\ \boldsymbol\vert,\ \Vert,\ \boldsymbol\Vert$
+\endexample
+\noindent
+However, you can't use \cs{boldsymbol} after \cs{left} and \cs{right}.
+In particular, typing
+\hbox{\tt\\left\\boldsymbol\char`\|\ ...\ \\right\\boldsymbol\char`\|}
+will produce only error messages.
+
+\medskip
+\item"$\bullet$"
+Certain symbols on the bold fonts can't be accessed at all via \cs{boldkey}
+or \cs{boldsymbol}: These include bold versions
+${\fam\cmbsyfam A}$, \dots, ${\fam\cmbsyfam Z}$
+ of the ``calligraphic letters'' $\Cal A$,~\dots, $\Cal Z$ that you type
+as \cs{Cal A}, \dots, \cs{Cal Z},
+and bold versions {\tencmmib0}, \dots, {\tencmmib9}
+ of the oldstyle numbers
+\oldnos0, \dots, \oldnos9 that you get with \cs{oldnos}. If
+you really need to have these symbols, you will have to enlist the aid of a
+\TeX{}nician, or use \cs{pmb}.
+\endroster
+
+
+\subhead Fraktur Font \endsubhead
+
+The German Fraktur font, which is designed for use
+only in math mode, can be made
+available by typing \cs{loadeufm} in the preamble area
+of your paper. If you are using the preprint style,
+medium-weight Fraktur is loaded automatically.
+To produce a Fraktur letter, type
+\beginexample{\exboxwidth=3.75in}
+\exbox{}{\$\\frak g\$} $\frak g$
+\exbox{}{\$\\frak A\$, \\dots, \$\\frak Z\$} $\frak A$, \dots, $\frak Z$
+\endexample

+\subhead Blackboard Bold \endsubhead

+\AmSTeX{} has a ``blackboard bold'' font, \cs{Bbb}. Like \cs{Cal},
+it will work only in math mode, and only when applied to uppercase
+letters. This alphabet is part of the \filnam{msbm} font, and can be
+made available by typing \cs{loadmsbm} at the top of your file. (It is

+\subhead Poor Man's Bold \endsubhead
+
+\AmSTeX{} now has boldface versions of most math symbols. However, if you

+new fonts or font families, you can always get a poor man's bold version
+of bold with \cs{pmb}, as described in \Joy{}.
+
+
+\subhead Bold Greek Letters \endsubhead
+
+Bold Greek letters, both lowercase and uppercase, can be obtained by
+using the \cs{boldsymbol} construction, as described in {\bf Bold
+Characters in Math Mode}. The upright uppercase bold Greek letters are
+part of the ordinary bold font and therefore extra font loading commands
+do not need to be used in order to get them. However, the lowercase and
+slanted uppercase bold Greek letters are not loaded automatically, so
+you must specify \cs{loadbold} before using them.

+
+\head 5. Symbol Names
+\endhead
+
+The symbols in the \filnam{msam} and \filnam{msbm} fonts have been
+assigned ``standard'' control sequence names as shown below. All
+the symbol names are loaded automatically by the preprint style; if
+you are not using the preprint style, the command \cs{UseAMSsymbols}
+will have the same effect.
+This will add about 200 new
+control sequences to \TeX{}'s internal table. If you are short on
+space, or need only a few of the symbols, you can use a different
+approach to access just the ones you need. See the section {\bf The
+\cs{newsymbol} command} below.
+
+
+\subhead Special Symbols and Blackboard Bold Letters
+\endsubhead
+
+Certain symbols from the \filnam{msam} family can be specified by
+control sequences that will be defined as soon as the command
+\cs{loadmsam} has appeared in the file.
+
+First there are four symbols that are normally used outside of math mode:
+$$\vcenter{\halign to\hsize{\1{#}\hfil\tabskip\centering&
+ \hbox to.5\hsize{\1{#}\hfil}\tabskip0pt\cr
+checkmark&circledR\cr
+maltese&yen\cr}}
+$$
+These symbols, like \P, \S, \dag, and \ddag, can also be used in
+math mode, and will change sizes correctly in subscripts and superscripts.
+
+Next are four symbols that are ``delimiters'' (although there are
+no larger versions obtainable with \cs{left} and \cs{right}), so they
+must be used in math mode:
+$$\vcenter{\halign to\hsize{\1{#}\hfil\tabskip\centering&
+ \hbox to.5\hsize{\1{#}\hfil}\tabskip0pt\cr
+ ulcorner&urcorner\cr
+ llcorner&lrcorner\cr}}$$
+
+Finally, two dashed arrows are constructed from symbols in this family.
+Note that one of them has two names; it can be accessed by either one:
+$$\vcenter{\halign to\hsize{\1{#}\hfil\tabskip\centering&
+ \hbox to.5\hsize{\1{#}\hfil}\tabskip0pt\cr
+ \omit\hbox to.5\hsize{\hbox to\biggest{\hfil$\dashrightarrow$\hfil}\ \ %
+ \cs{dashrightarrow}, \cs{dasharrow}\hss}&dashleftarrow\cr}}$$
+
+The Blackboard Bold letters $\Bbb A, \dots, \Bbb Z$
+appear in the \filnam{msbm} family. Once \cs{loadmsbm} has appeared
+in the file, they can be typed (in math mode) as \cs{Bbb A}, \dots,
+\cs{Bbb Z}.
+
+The \filnam{msbm} family also contains wider versions of the \cs{widehat}
+and \cs{widetilde} as shown above in {\bf Mathematical Constructions}.
+
+
+\subhead The \cs{newsymbol} Command\endsubhead
+
+All other symbols of the \filnam{msam} and \filnam{msbm} fonts must be named
+by control sequences so that they can be used (in math mode only) when the
+fonts are loaded. This can be done all at once by typing the instruction
+\cs{UseAMSsymbols}, which will load in the file \filnam{amssym.tex}\null.
+This instruction is included in the preprint style, so the names are
+assigned automatically, which requires over~200 control sequences.
+
+If you are very short on space for control sequence names, and need only
+a few of these symbols, you can omit \cs{UseAMSsymbols}. Instead,
+assign only the names you will need by using a new \AmSTeX{} control
+sequence \cs{newsymbol} to create a control sequence that will
+properly produce this symbol. The control sequence can be either the
+``standard'' name, as listed below, or one of your own choosing.
+
+The list of symbols below shows for each symbol the symbol itself, a
+four-character~``ID'', and the ``standard'' name of the symbol.
+(The first character of the ID identifies the font family in which a
+symbol resides. Symbols from the \filnam{msam} family have {\tt1} as the
+first character; symbols from the \filnam{msbm} family have {\tt2} as the
+first character.)
+For example, the symbol $\nleqslant$ appears as
+\medskip
+\noindent\kern2\parindent\2{nleqslant}
+\medskip
+\noindent
+To produce a control sequence with this name, the instruction
+\medskip
+\noindent\kern2\parindent\cs{newsymbol}\cs{nleqslant 230A}
+\medskip
+\noindent
+appears in the file \filnam{amssym.tex}\null. This same instruction can
+be typed by a user who is not using the preprint style and has chosen not
+to load all the symbol names by \cs{UseAMSsymbols}. Thereafter, the
+control sequence \cs{nleqslant} will produce the symbol $\nleqslant$
+(in math mode), and will act properly as a ``binary relation''.
+
+A few symbols in these fonts replace symbols defined in \filnam{plain.tex}
+by combinations of symbols available in the Computer Modern fonts. These
+are \cs{angle}~($\angle$) and \cs{hbar}~($\hbar$) from the group
+``Miscellaneous symbols'', and \cs{rightleftharpoons}~($\rightleftharpoons$)
+from the group ``Arrows'' below (and \Joy, Appendix~F). The new symbols will
+change sizes correctly in subscripts and superscripts, provided that you
+are using appropriate redefinitions. In order to use \cs{newsymbol} to
+replace an existing definition, the name must first be ``undefined''.
+Here are the lines you must put in your file if you are not using the
+preprint style or \cs{UseAMSsymbols} (which perform the redefinition
+automatically):
+\medskip
+\begingroup
+\parindent=2\parindent
+\obeylines
+\cs{undefine}\cs{angle}
+\cs{newsymbol}\cs{angle 105C}
+\cs{undefine}\cs{hbar}
+\cs{newsymbol}\cs{hbar 207E}
+\cs{undefine}\cs{rightleftharpoons}
+\cs{newsymbol}\cs{rightleftharpoons 130A}
+\endgroup
+\medskip
+\noindent
+These symbols are flagged in the tables below with a ``{\eightpoint(U)}''
+as a reminder that they must be undefined.
+
+Note in the tables that some symbols are shown with two names. In such
+cases, either one can be used to access the symbol.
+
+% since the symbol tables are set in displays, decrease the skip
+% above, so that the space between a section heading and table is
+% not so large.
