\Monograph sets `\demofont@' and `\proclaimfont@' when the names

Date reported: 28-AUG-1991 (mjd)

In a \ref, when using \book, we might as well print out \eds and
\pages or \page info (even though in AMS style this information
is normally omitted). \eds will print anyway if \by is omitted, so the
problem case is only when both \by and \eds are used in the same
reference (surely it's a bit rare in citing a monograph to list both
the author and an editor...)

Spacing above/below \block is imperfect. When used in
vertical mode, the \noindent causes
the short dislay skips to be used, which is then overcompensated
for, on the top only, with the \vskip\abovedisplayskip.

%      \block is intended for typing long quotes in a block, indented
%      on both margins. If we're not in horizontal mode, we do a
%      \noindent to avoid getting an extra blank line before the
%      display.

The definition of \page in \toc@ needs to be localized, otherwise

The AMSTeX User's Guide contains an incorrect example regarding the
TOC entry for \head.

> It turns out that I was misled by the
> AmSTeX 2.0 User's Guide which is not very clear about how to use

> \toc
> ...
> \head Continuous complex-valued functions\page{1}\endhead
> ...
> \endtoc

> I think this may work if there are two spaces between `\head'
> and `Continuous', but it certainly doesn't work with one space which
> is what appears to be in the User's Guide.   Fortunately, I was
> able to work out the correct syntax by examining the macro definition

File: amsppt.sty
Date reported: 17-MAY-1991 (mjd)

An author in a \ref...\endref structure used \no for the reference
number and also mistakenly used \no  to attempt to produce an issue
number. This resulted in the reference number having the issue number
value. It should be fairly simple to add an \ifvoid test when
putting reference data in a box to make sure the box is void;
if not, give a warning to the user about the command being used twice
inside one \ref (or \moreref or \transl) unit.

It seems that there was an error in copying the definition of \pmb@
from the TeXbook (p. 386)---there should not be a minus sign in
"\kern-.05em".

---Made some additional adjustments to tune the `boldness' further
(it's hard, though, to find a good compromise that produces
distinctly bold subscript characters and not too-bold text-size
characters).

Corrected: Version 2.1, June 1991

(1) In the second prompt message "fonts" should be changed to "files".
 (2) Maybe a warning about not needing to press Return key.
 (3) Error during TFM file move step did not prevent the
 "AMSTeX successfully installed" message from appearing.
 (4) Omitting the initial backslash from the  directory names given
 in response to the questions causes problems.

(1) corrected Version 2.1, May 1991
(2) Many DOS applications do not require use of Return key; left as is.
(3) Wording of final line changed for Version 2.1, May 1991
(4) Warning about necessity of backslash included in Version 2.1, May 1991.

User's guide should explain how to make an amsppt format file, not just
an amstex format.  For users with smaller, comparatively slower systems,
this saves quite a bit of time every time they run AMSTeX.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: AMSINST.TEX (now part of AMSGUIDE.TEX)
Date reported: 11-DEC-1990

Font cmbsy10 used in installation guide at a large size (18pt)
caused problems for some people who don't have it at that size.

---Problem has been resolved in the new amsguide.tex that incorporates
the installation instructions, by eliminating the large title where the
font occurred.

Corrected: Version 2.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: AMSTEX.TEX
Date reported: 3-DEC-1990

\loadeusm, etc. should not do \newfam if the family is already loaded
(should check to see if, e.g., \eusmfam is already defined).  One
user ran into trouble because \loadmsam, \loadmsbm and \loadeufm
were done in the format file and therefore when amsppt.sty was
loaded the three family assignments were duplicated.

---Changed the \load commands to undefine themselves after their
first use. This also saves a little main memory.

Corrected: Version 2.1, June 1991

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
File: AMSPPT.STY
Date reported: 28-NOV-1990 (H. P. Boas)

In definition of \thanks, \unskip was erroneously placed after the
period instead of before.

---Fixed by removing the period and requiring it to be typed by the
user. (\thanks could conceivably contain more than one sentence.)

Corrected: Version 2.1, June 1991

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

In \rightarrowfill and similar things the minus sign should be smashed
(as in plain.tex \relbar).  Compare

$$\buildrel\textstyle\sim\over\longrightarrow$$ % plain
  $$\overset\tsize\sim\to\longrightarrow$$ % AMSTeX
  $$A @>\tsize\sim>> B$$ % @>>> uses \rightarrowfill

---\rightarrowfill is defined in plain.tex, actually.  AMSTEX.TEX
also defines \rightarrowfill@. Smashing \rightarrowfill is nontrivial
(perhaps that's why Knuth didn't do it).

Corrected: Version 2.1, June 1991

Date reported: 5-NOV-1990

\intertext should add penalties to discourage page breaks; as a minimum,

The figure caption macros should treat

%% The algorithm used in determining whether to move a tag to a separate
%% line in \align is incorrect: it appears that the tag will be moved if
%% the space available is less than 2w (allowing for centering also), where
%% w is the width of the tag, when it would be better to not move it unless
%% the space is less than  (w + 1 em), and also uncenter the main part of
%% the display if necessary in order to fit the tag (this is the algorithm
%% used by \eqno & \leqno).
%%
%% Need to check \split also. This bug has been reported before
%% by other people also.

%% \@ins and perhaps also \topcaption, \botcaption should be

%% Joy of TeX description of using \midinsert and \topinsert
%% implies that the use of amsppt is not necessary, when
%% currently it is.

%% \alignat allows a tag to overprint rather than moving it to a separate

%% side. If not then something may need to be fixed.)
