\footnote{Heaven, I'm in Heaven...}
It's finally happened: this is the first issue of TeXMaG that I
haven't written a single article for (unless you count this bit at the
beginning). Other major accomplishments in this issue include a very
amazing macro from Martin Costabel which allows simple raster-image
characters to be drawn in LaTeX. Next time you need a schwa or fancy H
or whatever, you can get something presentable without using Metafont.
Also in this issue are the contents of the latest TUGboat, which for
the first time are making it out before the actual TUGboat does (for
those of you interested in joining/getting information about The TeX
Users Group, an address is in the back of this issue).
In other news, I'm told that some of the TeXMaG back issues are
available on the PCTeX Bulletin Board. Dominik (whose last name I
do not have) <DOW@HARVUNXW.BITNET> writes "What I did was this: I
logged on to the BBS, which is a Fido system. Its phone number is
(415) 388-1708, and the communications protocols are 300/1200 baud
No parity, 8 bit data, 1 stop bit. Once into the board (after giving
your name etc.) go to the Files section, area 4, which is called
\fido\texhax. There you will find a couple of issues of TeXMaG
(numbers 1 and 7 when I last looked)." If anybody knows how these got
there or could get the others up on the bulletin board, I'd like to
hear from you.

*Letters to the Editor*
Date: Tue, 20 Oct 87
From: SCHOEPF@DMZRZU71.BITNET
Subject: Re: timelines in \TeX
Hello Don,
You have this problem with the comment after the "\end{timeline}" in
LaTeX. Someone here recently had the same problem when he used
\newenvironment, so I looked into the LaTeX code to see how Leslie
Lamport does it. Here's what I found:
> % If \end{foo} needs to ignore blanks after it, then \endfoo should
> % globally set the @ignore switch true with \global\@ignoretrue.

*Left justified text within LaTeX's eqnarray environment*
By Chris Carruthers <CXC2F@UOTTAWA.BITNET>
Time and time again LaTeX users find that the the eqnarray environment
is very useful but that a feature which is lacking is the ability to
intersperse aligned equations with left-justified text. It turns out
that there is a very easy way to do this: use the TeX \noalign
primitive (as documented in the TeXbook). The following LaTeX sample
gives an example of how this might be done.
%%%----Pretend this is in typewriter type and that wasn't-------------
\documentstyle{article}
\begin{document}
\begin{eqnarray}
test &1 &2 \\
\noalign{\hbox{test}}
test & 3 & 4
\end{eqnarray}
\end{document}
%%%----OK, stop pretending now----------------------------------------
Which produces results something like the following (given the
limitations of ASCII text):
test 1 2 (1)
test
test 3 4 (2)

*sprite.sty: A LaTeX Macro*
By: Martin Costabel <XBR1DA29@DDATHD21.BITNET>
sprite.sty is a LaTeX macro that allows you to define in a quick and
dirty way your own symbols. You just have to define the character as
a dot pattern on your screen and enclose it by \sprite and \endsprite
commands. Of course, I know, TeX is awfully professional and this
primitive technique will not provide results as good as a MetaFont-
designed character or even one drawn using device-dependent \special
commands, but if you just need one special character or some cute
little symbol and you don't have the time/brains/MacIntosh/
superuser-privilege/money-for-AmS-fonts/or-whatever-is-necessary for
a professional solution, this might produce acceptable results.
The following SPRITE.STY and SPRITEUSE.TEX files should explain
themselves. Two words of caution are in order, however:
Warning #1: Do not use many of these home-made characters on one page.
Otherwise you will see the "TeX capacity exceeded" error message. In
SPRITEUSE.TEX, my Atari ST on which I am doing most of my TeX work,
finished the first page all right, but on the second one it stopped
after the 'F'. Our VAX finished both pages.
Warning #2: If you tend to believe that your favorite Laser printer
can print every .dvi file, you may be in for a surprise. Some
DVI-drivers are not very good in printing \vrule s (out of which these
characters are composed). Even if it looks good on a screen previewer
or on a dot matrix printer, your Laser printer may produce weird
error messages or garbage without any error message. Our Canon LBP8
interpreted the \ScriptH as a command to print one horizontal bar and
to screw up the rest of the page. The cheaper Kyocera printer did OK
as long as there was only one of these symbols in one line. Otherwise
it spread them over several lines. I wonder whether such an illegal
behavior has been observed in other cases (LaTeX picture environment
etc.) [[Editor's note: Our Apple Laserwriter driven by Nelson Beebe's
DVIALW printed the file with no problems as did our QMS-800 driven by
the Texas A&M DVILG8 (adapted from Tomas Rokicki's DVIGEN); DVItoVDU,
on the other hand, seemed to add extra pixels to certain "sprites".]]
SPRITE.STY is written using some of LaTeX's bookkeeping commands (like
\newcommand) that could easily be replaced by plain TeX equivalents.
It also uses two of LaTeX's internal LISP commands. If one steals
these from LATEX.TEX, the translation to plain TeX would be very easy.
Another comment: One cannot use the orthodox LaTeX
\begin{sprite}..\end{sprite} style, because this hides all definitions
made in between from outside use.

*The Toolbox*
From Rainer Schoepf <SCHOEPF@DMZRZU71>, we have some assorted macros
for high energy physics texts. Rainer writes: In high energy physics
there is a special notation consisting of a symbol (e.g. p)
overprinted by a slash, pronounced: p-slash. \not p does this, of
course, but it doesn't look as it should. After some experiments with
slashes from different fonts we arrived at the following two
solutions. The second of these does also vertical positioning.
Therefore the first one looks better if there are several slashed
symbols with different height and/or depth in a line.

\def\slasha#1{\setbox0=\hbox{$#1$}#1\hskip-\wd0\hbox to\wd0{\hss\sl/\/\hss}}

\dimen0 by-\ht0\advance\dimen0 by\dp0\lower0.5\dimen0\hbox

% Four macros for Dirac's bracket notation of expectation values
\def\bra#1{\left< #1\right|}
\def\ket#1{\left| #1\right>}
\def\bracket#1#2{\left<#1\mid #2\right>}
\def\EV#1#2#3{\bra{#1}#2\ket{#3}}
% And finally a macro for printing so-called `normal ordered' products
% They are denoted by a colon on either side
\normalord#1{\mathopen{:}#1\mathclose{:}}
%---------------Cut here---------------------------------------------
My own contribution this month is a macro for what I believe is a
European convention for indicating vectors requested by a visiting
professor at Harvey Mudd College. The \undertilde macro puts a tilde
under the character in its argument. This command should work with any
math character, although the best results will be arrived at with
letters and numbers. To use \undertilde with a non math-italic letter,
you will need to include the typeface command in the argument to
\undertilde, e.g., \undertilde{\rm B}.

_not_ be forwarded to TeXHAX) may be sent to TeX-L@TAMVM1.
LISTSERV@TAMVM1 also has file archives that may be of interest to TeX
