AMSLATEX.BUG, 18-JUN-1991

Bugs in the AMS-LaTeX distribution.  Items listed at the end, marked
with "%%" at the left margin, have not yet been dealt with, but are
listed here in case the information might help some users, and to record
the fact that they have been reported to the AMS.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstex.sty
Date reported: 27-AUG-1990

\frac needs to have \protect when used in ``moving'' arguments like
\section commands, \caption, etc.   Changed so that \protect is not
needed (as in ordinary LaTeX).

Corrected: 30-AUG-1990

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstext.sty, amsbsy.sty, ?
Date reported: 30-AUG-1990 (A. Fyfe)

The ifundefined test involving \RIfM@ to check whether certain
definitions have already been made is unreliable.

Typically the test looked like this:

\@ifundefined{RIfM@}{
\def\RIfM@{\relax\protect\ifmmode}
...
}{}

The correction involved taking out the test entirely. The additional
overhead in processing time and (perhaps) maintenance is negligible.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstext.sty
Date reported: 12-SEP-1990

The definition of \ref has an extraneous blank space:

...
             \@warning
                {Reference `#1' on page \thepage\space undefined}%
          \fi} <---------------- unnecessary space after the }

The definition of \pageref has a similar problem at the end of the first
line.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstex.sty
Date reported: 19-SEP-1990

The align environment has a problem: if \notag is used on
the last line, numbering will be suppressed on the first line also. 

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amslatex.tex
Date reported: 19-SEP-1990

\qed doesn't work well when \end{pf} occurs immediately after a display. 
The space preceding the box doesn't disappear.  The user can get around
it by doing 

\renewcommand{\qed}{} \qedsymbol

just before the \end{pf}, but this is not obvious from the
documentation.

Improved documentation: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 19-SEP-1990

\abstract should use \trivlist so that a blank line after
\begin{abstract} will be properly ignored.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 19-SEP-1990

The ctagsplt option should be turned on in AMSART.STY
to conform to J. AMS style.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 19-SEP-1990

\bysame should be defined in amsart.sty (perhaps in
\thebibliography) instead of being added by BibTeX, because some
users will not be using BibTeX.  Also \toappear needs to be added.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart10.sty
Date reported: 19-SEP-1990

\paragraph uses \spaceskip when it should use \the\fontdimen2\the\font
(\spaceskip will always be zero unless it is explicitly set).

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amslatex.tex
Date reported: 20-SEP-1990

Table captions write the entire caption to the .aux file.  Need to use
the optional [] feature to shorten or eliminate the text being written
to the .aux file.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 21-SEP-1990

\\ in title should be translated to a space in the running heads,
not comma + space.

\def\@title[#1]#2{\def\sh@rttitle{\def\\{\unskip, \ignorespaces}%
   \ignorespaces#1\unskip}%
   \def\thetitle@{\ignorespaces#2\unskip}}

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amslatex.tex
Date reported: 29-SEP-1990 (E. Neuwirth)

< amslatex.tex mentions a file
< fontsel.tex in directory
< fontsel,
< but this file is missing
< (on e-math.ams.com)

The entire "fontsel" package from Mittelbach and Schoepf is now
distributed in unchanged form.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: testart.tex
Date reported: 27-SEP-1990 (D. Rajan)

Testart.tex: the documentstyle option ``syntonly'' is commented out.
This means that later on when the user is asked if they want to
add \syntaxonly, they will get an error message if they do.

Rajan also was confused about the meaning of the vertical lines at the
margins towards the end of testart.tex and thought they were a mistake.
Perhaps some mention or a marginal note could be added to clarify.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: test.bib
Date reported: 28-SEP-1990 (D. Meade)

The @ in the tech-support e-mail address, in the file test.bib, causes
a BibTeX error. BibTeX doesn't have any way of commenting out @
characters! Change @ to "at".

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: testart.tex
Date reported: 28-SEP-1990 (D. Meade)

Extra \\ before \end{align} in testart.tex (lines 1540,1546) causes a 
blank line with an equation number.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstex.sty
Date reported: 18-OCT-1990

\Tag@ fails to give an error message in the situation it
was intended for (more than one ampersand in a single line).

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 18-OCT-1990

By convention \thetitle@, \theauthors@, etc. should be
\@title, \@author, etc. (cf. article.sty)

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart10.sty
Date reported: 19-OCT-1990

Final argument of \subsubsection in amsart10.sty needs to be put in
braces: {\defaultfont\it} 

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 30-OCT-1990 (P. Smith)

In amsart.sty, in definition of \ps@plain, the statement

       \let\@evenfoot\@oddfoot

has to come AFTER the definition of \@oddfoot, not before.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: AMSTEX.STY
Date reported: 5-NOV-1990 

\rightarrowfill@ and similar things should be smashed (like plain.tex
\relbar).  Compare 
$$\buildrel\textstyle\sim\over\longrightarrow$$ % plain
$$\overset\tsize\sim\to\longrightarrow$$ % AMSTeX
$$A @>\tsize\sim>> B$$ % @>>> uses \rightarrowfill

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: AMSTEX.STY
Date reported: 5-NOV-1990 

\intertext should add penalties to discourage page breaks; as a minimum,
there should be \penalty\predisplaypenalty added before the second
\vskip:

\def\intertext@{\def\intertext##1{\noalign{\vskip\belowdisplayskip
 \vbox{\normalbaselines\noindent##1}%
 \penalty\predisplaypenalty \vskip\abovedisplayskip}}}

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amslatex.tex
Date reported: 27-NOV-1990 

Need to include preload.med in list of files.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 28-NOV-1990 (BNB)

\author[xxx]{} with no author name but substitute for running head adds
unwanted space between title and whatever follows.  Could be fixed by
defaulting \sh@rtauthor to \sh@rttitle in the absence of any author.

Also: if [] is empty, \and should not be added in the internal code.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsbk11.sty, amsbk12.sty
Date reported: 11-DEC-1990 

Using the 11pt or 12pt options with the amsbook documentstyle,
LaTeX goes into an infinite loop.

The fix involves doing away with amsbk11.sty and amsbk12.sty entirely
and reorganizing the input statements in amsart.sty, amsbook.sty and
subsidiary files.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 7-JAN-1991 

It might be better to define \newblock as in article.sty (even though
it is not really relevant to AMS style), in order to avoid extra hassles
in handling electronic submissions.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsfonts.sty
Date reported: 12-JAN-1991 (H. Aslaksen)

\Box etc. should probably be defined by default, for the utmost
compatibility with older LaTeX files.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty 
Date reported: 22-JAN-1991 (M. Piff)

The "pf" environment should be reimplemented using \trivlist so that
if the first thing is a numbered list the first item will be "run-in"
instead of starting a new paragraph.

Reported by M Piff in UKTeX, 91#3.  (The problems with \qed reported by
Piff in the second part of his mail have no easy solution; there are
complications related to, e.g., displayed equations at the end of
a proof that he didn't address.)

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 28-JAN-1991 (J. M. Rynning)

\rom in \@svsec should include the following period.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsbsy.sty
Date reported: 28-JAN-1991 (J. M. Rynning)

\boldsymbol in a subscript gives incorrect font size (e.g., 6 instead
of 7, in 10pt text).

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstex.sty, amsfonts.sty
Date reported: 31-JAN-1991 

\minaw@ is declared both in amstex.sty and amsfonts.sty.  Uses up
an extra dimen register unnecessarily.  Should only be done if undefined.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsbsy.sty 
Date reported: 7-FEB-1991 (MJD)

The error in \pmb@ that was carried over from amstex.tex needs to
be fixed here also.   (change \kern-.05em to \kern.05em)

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 12-FEB-1991 (D. Mostardi)

Empty argument of \subsection results in a double period.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty 
Date reported: 15-FEB-1991 (MJD)

Add \curraddr, and optional arguments for \address and \email
to specify different combinations of multiple authors and address.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amstex.sty  
Date reported: 5-FEB-1991 (S. Samuels)

@  column specifier in \multicolumn doesn't work because the catcode
gets read wrong.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 17-APR-1991 (MJD)

Put back \upperspecialchars hook in \uppercasetext for greater
flexibility.

Changed name to \upchars@.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amscd.sty 
Date reported: 18-APR-1991 (I. Zakharevich)

\CD does automatic numbering of "lines" when it shouldn't.

Suggested fix (Zakharevich): insert \restore@math@cr\default@tag after
\Let@ on line 56 of the file amscd.sty (compare with \smallmatrix,
amstex.sty).

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.sty
Date reported: 24-MAY-1991 (J. Wilczek)

For sectioning commands the optional argument in square brackets isn't
the one that should be sent to the table of contents; the full section
title should be used instead. This affects at least the definition of
\@sect in amsart.sty and \@chapter in amsbook.sty.

Corrected: Version 1.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsbook.doc/sty
Date reported: 2-JUL-1991 (mjd)

Definition of \pf should have \hskip\labelsep inside \item[...]
(as in amsart.sty).

Corrected: amsbook.doc/sty, version 1.1a, July 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.doc/sty, amsbook.doc/sty
Date reported: 11-JUL-1991 (W. Carlip)

pf* environment doesn't work. The \begingroup \endgroup around
the temporary modification of \proofname cause problems (because
\pf was changed to use \trivlist).

Corrected: amsart.doc/sty, amsbook.doc/sty version 1.1a, July 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.doc/sty
Date reported: 22-JUL-1991 (P. Johnson)

\email and \curraddr are overwriting previous information; only
the last one in a multi-author paper is printed.

Corrected: amsart.doc/sty, version 1.1b, July 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: testart.tex
Date reported: 24-JUL-1991 (mjd)

First \email doesn't have the @ doubled properly.

Date reported: 18-JUL-1991 (D. Love)

\nofiles command prevents creation of .aux file.

Corrected: amslatex.tex, version 1.1a, July 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amslatex.toc
Date reported: 18-JUL-1991 (D. Love)

Reference to \sevrm in .toc file is bad for people who already
have the New Font Selection Scheme installed. \protect needed for
"\the" in \LaTeX redefinition.

Corrected: amslatex.toc version 1.1a, July 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: amsart.doc/sty
Date reported: 29-JUL-1991 (O. McGuinness)

Special characters \i, \ss, etc. not handled properly in
\uppercasetext@ (missing call to \upchars@).

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: fontdef.ams, amsfonts.sty
Date reported: 5-JUL-1991 (K. Barthelmann, F. Jensen)

References to eufb14 should be removed; the font is not part of the
official AMSFonts distribution any longer.

Corrected: amsfonts.sty version 1.1a, 3-SEP-1991

From Barthelmann's mail:

> 1. The use of \dashrightarrow or \dashleftarrow gives an "Undefined control

The \mathchardef used to create \dabar@ needs a \global prefix.
