AMSTEX.BUG: Bugs in the AMSTeX distribution (amstex.tex, amsppt.sty,
amssym.tex, amsppt1.tex, amstex.ini). 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.

Missing \endkeywords, \endsubjclass, and \endsubhead, among others,
produce a puzzling error message ("Use of \next@ does not match its
definition").

---Involved substantial changes to \nofrills mechanism (internal
implementation, not user interface).

Corrected: Version 2.1, June 1991

Line breaking in \Refs section doesn't work properly after explicit
hyphens, or after mathbins and mathrels, because of setting the
text in \hbox's.

---Substantial changes in the internal workings of \ref and related
macros.

Corrected: Version 2.1, June 1991

\widestnumber\item doesn't work as claimed in the user's guide.

\penaltyandskip@ macro needs to have \par at the beginning.

The figure caption macros should treat

       \fc{Figure 1}
       \endfc

the same as

       \fc{Figure 1}\endfc

In other words the test to see if the second argument is empty should
work even when the second argument is a blank space.

Corrected: Version 2.1, June 1991

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,
there should be \penalty\predisplaypenalty added before the second
\vskip:

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

Corrected: Version 2.1, June 1991

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

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: 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

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.

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.

It seems that there was an error in copying the definition from \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
