Subject: TeXhax Problems.
We must appeal for your patience. These are nightmare days for anyone
involved with a mail system. As most readers will know by now, one
of the primary targets in the recent invasion of Berkeley 4.3 Unix
systems was the sendmail program, and the often panicky response has
not done the network any good at all. It is our strong impression that
network performance has declined steadily from issue 100 through 104,
and this is not surprising.
You are likely to find yourselves receiving truncated copies (many did
of 104 but this also happened with 95, so it is not unique to the
present state) duplicate copies (many did of 103) and heaven knows what else.
Our return mailbox is a minimum of half a Megabyte on each issue now,
and there is an almost equal amount bucked back into the texhax submissions
by mailers which can't or don't read the Errors-to: line. We have only
minimal control over any of this. Our people are working long and hard
to control any errors that can be traced to our own mailer, but the
complex topology of the network makes the sources hard to isolate in
some cases. We expect that things will get worse before they get better.
Since we cannot be sure who got good copies of 104, we will have to
resend. Please bear with us if you get two copies.
For the BITNET people, We can only say that every address received from
the Stanford list was put onto our server. We don't know how
to reach the people who are not getting bitnet copies, there is a
traditional logical problem there
"If you happen to be deaf or dumb
"Or do not understand a word I say,
"Then wave your hand to signify as much."
A.E. Housman
The BITNET (non)recipients who have communicated directly with us do
not appear explicitly on the SCORE listing, so they must be on some
BITNET remailer or other. We have certainly tried not to leave any
such remailer out. In fact we hope to foster them.
We are hoping that it will be possible to set up a LISTSERV archive of
TeXhax and other things here to serve the BITNET community better.
We can only appeal for patience. At the moment we are nearly
buried under the more direct mailer problems.
One last, and we hope a positive note. The trailer now includes a
list of the generally current versions of TeX and Metafont software.
These versions shown represent the versions that have been ported
over a wide range of systems, and should never be more than one
behind what is on SCORE. (For example, TeX is officially at 2.94,
but we want to know from a few more sites that it works on a wide range
of machines before listing it).

Subject: Multipage split tables
Keywords: tables
I may have what Greg McGary is after.
I have a macro for splitting tables, and it is very easy to use:
just put \splittable between two lines of the table. Unfortunately
it is for my own set of table macros which are too long to post.
The idea though is simple, and should even be usable with LaTeX tables
with a bit of study.
First put the title, \halign command, preamble, and column headings in
one or two global macros. Use them to start the table. Somewhere in
the table, between two lines put \splittable which should be defined to
o end the \halign (\crcr\egroup)
o say continued
o end any boxes (\vfil\egroup)
o end the insert (\endinsert)
o start new page (\pageinsert etc.)
o regurgitate the table title
o regurgitate the table headings.
What this will NOT do is split the table automatically at the bottom of
the page. To do that would require a different class of insertion for
long tables and then it would be very difficult to preserve the order
of tables in the output. Besides, I get so few very long tables that
it is easier to split them by hand.

Subject: RE: Multi-page tables with page headings on each page
Keywords: tables
In TeXhax V88 #100 (the first issue from Washington) Greg McGray asks about
multi-page tables with column headings on each page.
For LaTeX users:-
There is a file in the Aston Archive ( and probably also in the US
wherever the score directories are now held) called taj.txh. This is
supertabular which allows multipage tables with headings repeated on
continuation pages. Supertabular is described in earlier issues of TeXhax.

Subject: Wanted: PStoDVI
Keywords: dviware
I know that there are such things as DVItoPS programs that convert
a DVI file to a PS file. I know that there are PStoXXX programs that
convert a PS file to an XXX file where XXX is some laser printer. What
I need is a PStoDVI program that would convert a PS file to a DVI file.
It seems that these days a lot of documentation is being distributed in
the form of Postscript files and I dont have a Postscript printer. I
DO have an old clunky Cannon LBP8A1 (the one with almost no memory) and
I have written a DVItoCANNON program that works nicely with it (which
cannot be said for the Beebe drivers which only work on the A2). I doubt
that I will find a PStoCANNON program and I sure don't want to write
one! Hence ``PStoDVI psfile | DVItoCANNON > /dev/cannon''. What's
a poor TeXhacker to do???

Subject: Problems with LaTeX picture environment
Keywords: LaTeX
I have been struggling with the LaTeX picture environment for the
past two days. I am trying to align several superimposed objects.
I have isolated the problem down to a very small core. Here is
the sample problem: I want a square with cross hatching with an
inscribed circle and a disk located at the center whose diameter
is half the length of the side of the square. Enclosed is a
LaTeX file which is very simple and which prints five obvious
pages most of which fail in alignment. The first page prints
a cross-hatched square with an inscribed circle and disk. It
fails to align. The second page prints a non-cross-hatched square
with a circle and disk and does align. The third page prints
both squares and both circles and fails to align. The fourth
and fifth pages are the same as the first and third but use a
version of the cross-hatched square created by a \savebox
with the dimensions specified while the first and third pages
use a version where \savebox was called without the dimensions
specified.
Help me please, what am I doing wrong?
Thanks,
Jeffrey Mark Siskind

The LaTeX command \stackrel{top}{bottom} is fine for most equations,

reactions too well. For example:
Pt/Rh catalyst

1120 K 5 atm
where one would want to have text and/or math both atop and below the
(usually) \longrightarrow .

Office: 72 DCL (217) 333-1925
Keywords: macros
Although I am loath to submit another version of this, the following changes
to texpictex.tex clip the line drawing to the bounding box. It works
in the standard way: just say \setboundscheckon.
Actually, this garbage should be done by extending the set of texpic/tpic
specials to provide a ``current clipping region''. Then, while those
changes are being made, you could slip in a modified arc command to avoid
computing arctan() in TeX and a texpic/tpic special to handle quads.
If someone does this, please do write, I'd love to use it.
%
% texpictex.tex -- The following macros over-ride certain definitions in the
% PiCTeX macro package. The net effect is that line-drawing is done using
% the \special's used by texpic (tpic). Several DVI printers understand
% and handle these specials.
%
% Currently, only straight lines are translated. Recently, I added a
% clipping routine to clip to the bounding box.
%

Subject: RE: including Macdraw and laserprep
Keywords: MacDraw, Laserprep
In the last couple of issues, questions about mixing Macdraw, Macpaint,
or most postscript files from the Macintosh have appeared. In our
environment, we have be successfully mixing the two (TeX and pictures).
We use DVIPS from Arbortext with no problem. NOTE: when using
the pictures, the `printer memory' needs to be reduced in DVIPS,
otherwise the printer will have problems.
The following is a response I sent out last time, but seemed to
get lost.

The infamous Laserprep problem. If I remember correctly, the Macdraw sample
that you have been using with DVIALW has an old laserprep file, or a `hacked'
version. The main problem with Macdraw (or Mac-anything) is having the correct
Postscript dictionary (laserprep-xxx). When we got Arbortext's DVIPS program,
it included a laserprep dictionary. However, our Macs where using Laserprep 40, so
the Postscript output by the Macs would not work with the Laserprep dictionary from
Arbortext. So, we had to move the Laserprep 40 dictonary from the Mac to our Apollo
system. Thanks to Jim Sterken's comments in the Arbortext Laserprep for making it
easy to get the new Laserprep dictionary working.
To get the Laserprep dictionary from your Mac - (from JS's comments)
To put the PostScript description of a MacDraw document into
a file, select the PRINT option, and then LASERWRITER from the
menu. Note that the LaserWriter driver must be installed in
order to do this. When the Mac comes back and says ``printing'',
press <flower>F together. A PostScript file will be generated
on the disk. If you press <flower>K you get a PostScript file
prefaced with the LaserPrep file. We don't know how you get
just the LaserPrep file itself, but one approach is to make
a document that is trivially short and then edit it---the
separation point between the LaserPrep stuff and the regular
MacDraw figure stuff is obvious.
It should be noted that some items in the Laserprep dictionary need to be
commented out. I have been able to send a MacDraw/MacPaint file to LPS40
with our `fixed' Laserprep.
Things to comment out (based on Laserprep 40 and JS's comments) -
The next step is to edit a few lines in your LaserPrep file to keep
it from trying to load itself in the printer permanently, and to keep
it from blanking the page before printing the figure---both of these
things cause problems when trying to merge MacDraw figures into TeX
generated pages containing other material. It is difficult to explain
which lines should be edited since this may change with each version
of LaserPrep released by Apple. Generally only five to ten lines need
be commented out to make things work. The following excerpts from
Apple's version 36.0 LaserPrep file show the lines we commented out
to make things work. If your version of LaserPrep is significantly
different from this, you are on your own to figure out what must
be done... After you've finished making the necessary changes to
LaserPrep, you should again verify that you are still on the right
track by concatenating your edited LaserPrep file and your MacDraw
test figure and transmitting them to your printer.

In Laserprep 40, there was a LARGE block of hexidecimal values. I had to comment these
out also. Found out later it was microcode fixes for the Laserwriter (not used by
our Apollo printer).
Finally, I was able to successfully host Laserprep 65 into our Postscript environment
by following these rules.
Good Luck!!!
PS. Maybe Laserprep files should be put into an accessible area for easy
FTPing.
Or is this a legal problem

I had the same problems when I tried to print an Encapsulated PostScript
file generated by Cricket Draw. By changing the line:
[] settransfer
into
%[] settransfer
I was able to print the ps file and I was also able to include it with
the psfig-macro into a LaTeX document :-)

Subject: Questions in TeXtures
Keywords: LaTeX, TeXtures
Can TeXtures run LaTeX as described in the LaTeX manual?
If it can what is the System configuration requiredment, such as main
memory, disk space etc?
How long does it normally take to print a page on a Image writer?
Thanks in advance.
Ghee.
