Date: 14 Aug 88 Message No: 008
To: TeX implementors and distributors
From: Barbara Beeton
Subject: TeX 2.93, again; LaTeX and AMS-TeX
I received the following message from Don Knuth on July 13, as I was
preparing to go to TeX88 in Exeter:
Subject: minor problem with TeX version 2.5
The variable cur_order should be initialized to something, because
there are Pascal compilers that don't allow you to say "a:=b" when
b hasn't been given a value (even if that value is never used).
I'll put that fix into version 2.93 so that the changes are confined
to TEX.WEB alone. The bug really won't hurt anybody except a brand
new implementor.
So this change should be incorporated into TeX 2.93; there will be no
change in the version number.
Below you will find the new additions to TeX82.BUG, a comparison between
the TeX.WEB files for versions "2.93a" and "2.93b", and additions to
ERRATA.TeX. There were no changes to TRIP.*.
All relevant files are now up to date at SCORE.
TRIP.TeX and TRAP.MF were sent several weeks ago. I will be breaking
the .LOG files into pieces and sending them soon, also the "auxiliary"
files -- .TYP, .PL, etc.
There have been some recent changes to LaTeX. The following items are
included below: differences between the addenda file from 12 May 88
through the latest, and differences in SliTeX.TeX from 10 November 86
through 8 June 88. I have no earlier version of the addenda file to
compare; if you would like the complete file sent, please let me know,
and I will be happy to mail it. A file of differences between LaTeX.TeX
of December 85 through the latest is being mailed separately; it is very
large ( >52K bytes), and may have to be mailed in more than one section.
I am sorry that I could not use a more convenient version of LaTeX, but
the only ones I have available are from December 85 and April 88, and
it seemed that using the older one would be helpful to more of you,
since I have not previously distributed any LaTeX updates. There are
some notes at the beginning of the LaTeX differences file that you
should read before doing anything with the file.
A small change has been made to the distribution version of AMSTeX.TeX,
to fix a bug in \dots that shows up in some rather obscure circumstances.
The details are described in the file AMSTeX.CHG. Both files are at
Score in <TEX.AMSTEX> . AMSTeX is now at version 1.1d. If you are
distributing AMSTeX and cannot retrieve the files from Score, please
let me know, and I will mail you the up-to-date files; please include
a list of all the AMSTeX-related files you now have, and their dates.
Other files in the group have been changed within the past year, but
the changes were not too well advertised.
Finally, please acknowledge your receipt of this message. Several new
names have been added to the list, and some addresses have changed. I'd
like to make sure that they're all working.
