Subject: When calling TeXserver, make sure you have enough room!!
Keywords: TeXserver, disk space
Noticing that the TeXserver (@uk.ac.tex) had ground to a halt on 13th
August, I attempted to restart it and discovered that the account had no
disk quota left. Investigation showed that nearly 19MB of traffic had
been bounced back since it was last started (on the 9th); I didn't have
time nor inclination to read all of the bounced mail, but a very large
proportion was there because the addressee (who'd requested the traffic
in the first place) didn't have sufficient disk quota to receive all the
incoming mail.
So please ensure that you _have_ got room for all that you request: if
you're not sure how much space will be required, each directory in the
Aston Archive contains a 00files.txt file which lists file sizes in
bytes, whilst the 00directory.size file lists the entire archive, with
sizes given in (512-byte) blocks --- this file itself is nearly 2200
blocks long however.

Subject: Centering equation number in Latex
Keywords: LaTeX, centering, equation number
If I have a multi-line equation in Latex, I would like to vertically
center the equation number. One way to do this is to use eqnarray, and
\nonumber all but one of the middle lines. This is really inconvenient,
and doesn't really center the eqno, especially if there are an even
number of lines. Another way to do it is \begin{equation}
\begin{array}{rcl} ... \end{array} \end{equation}. This will put the
eqno at the correct position, but has two problems: you need to put a
\displaystyle in each array element, and the vertical spacing between
lines is too tight.
Somebody else must've run in to this problem. Any good solutions?
Thanks! Mike Blackwell mkb@cs.cmu.edu

Subject: An exceptionally disturbing evaluation of \if
Keywords: \if, TeX
When I define a control sequence, say \steve, to begin with two
numerals, then compare this control sequence to \empty using
\if, the result is true! For example, the TeX code
\def\steve{22}
\if\empty\steve \immediate\write16{\steve\space is empty!}\fi
yields (with \tracingall) the following result in the log file
{\if}
\empty ->
\steve ->22
{true}
{\immediate}
\write->\steve \space is empty!
This is most perplexing, especially when one considers that the
definition \def\steve{23} yields a false result in the same \if
statement. This behavior seems to be true for any definition of
\steve where the first two characters are identical numerals, e.g.,
the TeX code
\newcount\n \n=0
\loop\ifnum\n<1024
\edef\steve{\the\n}
\if\empty\steve \immediate\write16{\steve\space is empty!}\fi
\advance \n by 1
\repeat
yields (on the screen)
11 is empty!
22 is empty!
33 is empty!
44 is empty!
55 is empty!
66 is empty!
77 is empty!
88 is empty!
99 is empty!
110 is empty!
111 is empty!
112 is empty!
.............
996 is empty!
997 is empty!
998 is empty!
999 is empty!
Can anyone explain this odd behavior? Is this a bug or a feature? By
the way, we use TeX C Version 3.1.

Subject: WriteNow and/or other proprietary formats to TeX
Keywords: WriteNow, TeX, proprietary format
I have a problem, requiring some translation from proprietary formats
into TeX. Namely, a colleague and I have written a 700 page mathematics
research book, full of equations. My colleague put almost of all of it
into WriteNow, a proprietary Macintosh Word Processor (also used on the
NeXT). We need to convert this to TeX, for publication. (Could be plain
TeX, or Latex, or whatnot).
The ideal would be a WriteNow to TeX translator, if such an animal exists.
Other possibilities: There may be some Macintosh product that converts
WriteNow to Macintosh Word Perfect 5.1. That would do it, as there is a
Word Perfect to TeX translator, I believe from ArborSoft.
Another possibility: I've been told that WriteNow can export to "RTF
format", whatever that is. I don't know if that would preserve the
equations or not. Someone wrote me that he thinks there is an "RTF to
TeX converter" on some "server on the Internet".
Any ideas, based on the above or otherwise, would be appreciated. Products
could be shareware, commercial or any mix.
As I've just requested to be added to the mailing list, I might not receive
a response posted to the group; so it probably would be best to email anything
to me. I'll summarize for the mailgroup.
Thanks very much in advance,
Sincerely yours,
Saul Lubkin

Subject: Virtual font use on the Macintosh.
Keywords: Macintosh, virtual fonts
Virtual font use on the Macintosh.
Virtual fonts are necessary for correct hyphenation of
languages with accents as planned by D. Knuth for TeX 3.0.
Neither OzTeX nor Textures, the two TeXs on
the Macintosh, have any plans to support virtual fonts with
their printer drivers in the near future. (Check for yourself
with the authors A. Trevorrow <NKS661@CSC1.ANU.EDU.AU> and
Brian Smith <barry@reed.bitnet>.)
However they support TeX 3 at the composition
level. That means one can get a valid .dvi file, provided one
uses font metric (.tfm) files coherent with the the new
virtual versions of the computer modern fonts. There are two
versions both recently released.
--- the "em" fonts of Arbor Text, contact
help@arbortext.com. They seem to include virtual versions of
Adobe Times etc.
--- the "dc" fonts of Bochum posted for anonymous ftp
transfer at ymir.claremont.edu (134.173.4.23)
Both of these use the 1990 Cork standard for the full
eight bit range 0-255 (see Ferguson's article TUGboat Nov(?)
1990).
What is still missing on the Macintosh is a
"dvi ==> postscript" converter (printer driver) that handles
virtual fonts. The obvious candidate is DVIPS of Tom Rokicki.
HAS DVIPS BEEN, OR IS IT BEING COMPILED FOR THE MACINTOSH??
This compilation would be an important step. It would,
for the first time on the Macintosh computers, make it
possible to use TeX with correct hyphenation of European
languages.
Laurent Siebenmann
<siebenmann@LALCLS.decnet.cern.ch>
PS. I expect that modulo some tricks, it would
then be possible to use the built-in Textures and OzTeX
previews for proof versions providing one is willing to
recompile for the final dvips printing.

Subject: re: Selecting which pages get into the dvi file?
Keywords: dvi files, selecting pages
In a recent TeXhax, Graham Toal asks for a way to select which pages are
actually written to the DVI file, from TeX, in such a way that all other
processing works normally.
As it happens, I had a need for such code recently. It's specific to LaTeX,
though it can easily be adapted to other environments. First, the code; then
some explanation:
\nofiles
\newcount\Physpage \Physpage=0 \newif\ifDoship \newbox\Dummybox
\maxdeadcycles=999999 \let\Shipout=\shipout
\def\shipout{\global\advance\Physpage 1 \Doshipfalse
%
\ifnum \Physpage=2 \Doshiptrue \fi %Edit me!!
\ifnum \Physpage=5 \Doshiptrue \fi %Edit me!!
%
\ifDoship \let\Next=\Shipout
\else \def\Next{\message{(\the\count0:\thepage:\the\Physpage)}%
\setbox\Dummybox} \fi
\Next}
This code must be placed in the preamble of a LaTeX document. It MUST first
be edited to select a particular set of page numbers. Note the two lines
marked "Edit me!!". For each page you want to have go to the DVI file, you
must have one such line. Replace the "2" and "5" by the PHYSICAL page num-
bers of the pages you want to retain. (By physical page number, I mean the
relative position of the page in the document: The first page produced is 1,
the next is 2, etc.)
Note the use of \nofiles. This supresses the production of new AUX, TOC, and
such-like files. You must have previously run LaTeX enough times that your
table of contents, bibiliography, references, and such are all "stable" - a
run with this code active will not update them. Do not remove the \nofiles or
you'll end up with trashed versions of the AUX and related files.
When this code is active, LaTeX and TeX will go through all the motions of
typesetting every page of your document. However, only the selected pages
will end up in the DVI file. You'll get the usual TeX [nn] display for pages
that actually go to the DVI file. For all other pages, you'll get a display
of the form (p:q:r), where p is TeX's page number (what would have appeared in
the brackets had the page gone to the DVI file - or, more accurately, just the
number up to the first "." if you are using a style that uses multiple count-
ers); q is the page number as it is typeset; and r is the physical page
number. Since all these displays go to the LOG or LIS file, a single run with
no \ifnum lines will give you a simple table that you can use to determine the
physical page number corresponding to any LaTeX page number.
How it works: \shipout is the TeX command that actually causes output to be
written to the DVI file. It is handed a vbox containing the data that should
be shipped. The code re-defines \shipout so that, if the current page is not
selected, that vbox is simply saved in \Dummybox, and then discarded when the
output routine (which executes in a group) completes. The original meaning
of \shipout is saved in \Shipout, and used to send the selected pages to the
DVI file. In place of the \ifnum lines, you could substitute any code you
like for deciding whether to retain the current page. The \Physpage counter,
maintained by this code, contains the physical page number. \counter0 through
\counter9 contain the standard TeX page counters. (In LaTeX, the "page"
counter is \counter0.) \thepage contains the commands to typeset the page
number. \maxdeadcycles is set to a large value to disable a TeX sanity check
that would otherwise issue an error message if too many calls to the output
routine occurred with no pages actually being shipped to the DVI file.
Since non-\immediate \write's (and \open's) are executed as part of \shipout,
any such embedded in non-selected pages will end up being discarded. That's
why the \nofiles command is needed.
Obviously, testing every page number against every selected page is not the
most efficient way to do things. It's easy to come up with much more sophis-
ticated test strategies. However, for small numbers of selected pages, it's
probably not worth the trouble - the extra time is tiny compared to the time
to typeset the pages.

Dear sir,
I am a computer office of Hongkong University of Science & Technology.
We install the TeX 3.0 software recently.
One of our staff try to include a Postscript figures generated by
FrameMaker 2.1 but never able to get it printed. But if he use
FrameMaker 1.3 to generate PS figures, it can be printed successfully
after include it in the LaTeX document.
We have try to use dvips and dvitps but none of success. The
Postscript file from dvips can be viewed on the Sun Workstation by
the Postscript viewer (pageview) but just cannot be printed.
The Postscript from dvitps has even Postscript syntax errors as
shown below, if we view it with pageview program:
Bad font definition:
Bad font definition: endTexFig
Bad font definition: (b)o(y)f(F)m(rameMak)o(er)g(2.0.)-503 425 y(1)-988 b
Bad font definition:
Bad font definition: (\nEND-JOB test.dvi\n) print flush
Bad font definition: restore
However, the PS files generated from both dvips and dvitps can be
viewed on the Sun Workstation with the Gostscript program (version 2.2)
from GNU.
Here is the version for our dvitps and dvips programs:
dvitps - TeXPS version 3.11
dvips - 5.47
Any help and advice are very much appreciated.
Regards
David Yeung
