Subject: floppy TeX
it takes a bit of fiddling, but pcTeX on floppies is possible.
you can't put pcTeX and a previewer and all the support files on
one disc, but you can put things on two floppies - a TeX disc and
a previewer disc. you *might* be able to swing it with 360k
floppies, but you would have to throw away some fonts to shoehorn
everything in. with 720k floppies, proceed like this:
disc 1: tex.exe 226k (pcTeX)
*.tfm ca. 180k (in a suitably named directory)
plain.tex ca. 44k (in another directory)
total: ca. 450k
disc 2: dvi2scr.exe ca. 66k (maxview - we have a site licence)
*.pk ca. 330k (@180dpi - you only need one set)
total: ca. 396k
note that TeX only needs the tfm files and any format files you
specify. there is room for lplain.tex and a selection of laTeX
style files.
if your version of TeX or your previewer has references to the c:
drive wired in, use the pc-dos assign and subst commands to point
the references to your discs. set up .bat files to reduce head-
aches.
have fun. but don't hold your breath waiting for results, as
floppies are a lot slower than hard discs, and TeX does a *lot*
of disc access.

Subject: LaTeX question (^textheight)
This is a LaTeX question:
I want to make a variant of LETTER.STY also printing the letterhead.
The letterhead has to be higher up on the first page, but I want the
bottom lines flushing on the "titlepage" and on the following pages.
Therefore ^textheight has to be different on the first and on the
following pages.
But ^textheight seems to be a VERY GLOBAL variable. It always uses
the first assigned value and changing its value in a ^pagestyle
definition (using ps@newstyle) does not produce the desired
results. I know that usually one does not want to fiddle with
^textheight within a document, but on the other hand I do not think
my wishes are completely stupid.

Subject: LaTeX's \oval's
Has anyone hacked together a more accurate version of Leslie
Lamport's wondrous \oval ? I'm a little distressed with the
visual inaccuaracy of its results on our system when \thinlines
is in effect. I can improve matters very slightly by using
\thicklines, but given TeX's habit of working in sp's, can't
we get the junctions between the elements of the oval to line up
a little better ?
Some further bits:
1) Sebastian Rahtz's rotate and turn environments
Sebastian wasn't too upfront or helpful about what to do
if his wonderful PostScript \specials blow up on their
way through dvi2ps. One possible answer is that you need to
take out the /setspecial, /beginspecial and /endspecial
commands inserted by dvi2ps. Our version of dvi2ps came
from SR anyway, and it had these removed (by Piet V.O) to
facilitate psfig. I hacked around and added a -g option
which specifically leaves these out. This sadly screws up
psfile inclusion, but maybe we'll work it out one day...
2) Biggggg TeX
Has anyone got a WEB .ch file for a gross TeX ? I need to
print a document with huge xrefs and our version is too small
to handle them. I tried to figure out what to do, but its not
obvious, and a file together with some hints on using it
would be very much appreciated. What's that ? Oh, yes, Sun
threes under SUNOS3.4 (soon-to-be 4.0 - it came today!).
3) TeX -> ascii
Has anyone got something that will do *exactly* what troff
allows unix man pages to be ? That is - print it or view it
formatted ? I currently have a large bunch of elisp regexps
that I use to go from LaTeX to a VMS HELP format, but its
not perfect (particularly with verbatim stuff), and it would be
nice to start with an existing flat-file viewer, even if this
doesn't have HELP's structured browsing facilities. Please
don't mention Emacs Info - I love it, but I need to be able
view inside and outside of my favourite session manager. I
have heard of DVI->ASCII previewers: what do they do and
how good are they ?

Subject: Neat use of \left and \right delimiters
In TeXhax (v. 63) Brent Carruth asks how to put a system of linear
equations and its augmented matrix side by side as a displayed
equation. Actually, all you need to do is make each display
separately with smaller hsize and then place them side by side
(using the KISS principle). The general pattern would be something like
\centerline{
{\hsize = .4\hsize %twiddle for different gutter width
\vtop{$$
\eqalign{ <first aligned equation> \cr
<second aligned equation > \cr
. . .
<last aligned equation> \cr}
$$}
}
{\hsize = .4 \hsize %twiddle this too
\vtop{$$
\left(<first coefficient matrix row> \;\cr
<second coefficient matrix row> \;\cr
. . .
<last coefficient matrix row> \;\cr} \right |
\left. \matrix{ <augmented column> } \right)
[D$$}
}
}
Whats neat is that an augmented matrix is usually printed with a
vertical rule before the last column. So we make the rule the
right delimiter of the coefficient matrix (all columns but the last)
and have a null left delimiter for the last column (the \; jiggles the
spacing for better appearance).

Many journals still require endnotes rather than footnotes. I have been trying

really appreciate if anyone who has a macro that works just like \foot except
places these notes at the end of the text will send me a copy of the macro.

Subject: Question on dvi2ln3
Please post the following to texhax.
Thank you, A.R. Thompson
We are using a DEC LN03 plus with a standard rom containing five
frequently used fonts. We have been trying to modify dvi2ln3 so that when
these fonts are specified it will inform the printer and not try to load
the fonts themselves. We have made some progress but we still cannot seem
to get it quite right. Does anybody have a modified copy of dvi2ln3 with
the appropriate changes, or know what the changes should be?
If we figure it out on our own we'll make it generally available.

Subject: Nested braces in LaTeX
I've been trying to get LaTeX to give me a list of numbers
with nested right braces to label partial sums.
For example, something like this:
\ \ \
1 | | |
| | |
2 \ | |
10 | |
3 / \ |
| 21 |
4 | / \
/ | 36
5 | /
| |
6 | |
/ |
7 |
|
8 |
/
9
The main difficulty seems to be in getting the numbers
lined up. Notice the trial-and-error spacing in the
following code:
\documentstyle{article}
\begin{document}
$$
\begin{array}{l}
\left.
\begin{array}{@{}l}
\left.
\begin{array}{@{}l}
\left.
\begin{array}{@{}l}
1\\2\\3\\4
\end{array}
\right\}
10
\\ \,5\\ \,6
\end{array}
\right\}
21
\\ \, \,7\\ \, \,8
\end{array}
\right\}
36
\\ \, \, \,9
\end{array}
$$
\end{document}
It works, but there must be a better way.

Subject: Bug in some versions of dvi2ps/dvips?
I've encountered a problem in the translation of DVI files
PostScript using some of the common "dvi2ps" or "dvips" programs.
The right delimiter (e.g., \right] or \right)) on arrays and vectors
larger than about 3 rows is broken; that is, part of the vertical
line segment in the ] is aligned differently from the other part.
To produce an example of the bug, create a DVI file with the following
TeX vector in it:
$$\left[\matrix{x-\lambda\cr
0\cr
0\cr
0\cr
0\cr}\right]$$
On my PostScript output the right bracket is broken by the following:
1. The dvi2ps program using GF format fonts, with a description file
dated Sept. 8, 1986 by Dr. Mackay.
2. The dvips program using PK format fonts, version 0.83, by
Tomas Rokicki.
The bracket is NOT broken on output produced by the following:
1. An old (1985) version of the dvi2ps program using PXL format fonts.
2. Kellerman & Smith's "impress/dvi" using PXL format fonts.
3. UC Berkeley's dvitool program using PK format fonts (hearsay).
Does anyone have any insight into what's causing this (better yet, does
anyone have a fix)? Is it caused by character positioning not being
calculated in the official dvitype manner, as mentioned in the
documentation to the program?
If this problem has appeared in TeXhax before, I apologize, but
would someone give me the appropriate references?
Thanks,

I know it is hard to believe, but my signature on a letter does not

The TeX command:
$$ \eqalign{
x &= y, \cr
u &= v.} \eqno(4) $$
produces a pair of equations with the equation number, in this case, 4,
appearing on a line midway between the two equations, something like:
x = y,
(4)
u = v.
except, of course, that there is not so much space between the equations.
Is there some way to do this in LaTeX? The eqnarray environment seems to
put the equation number directly opposite one of the equations. This is
logically equivalent, I suppose, but seems somehow not as pleasing to the
eye.
The pleasantness to the eye is irrelevant; what's important is that it
be clear to the reader that the (4) refers to both equations. If this
pair of equations is a single unit that is to receive a number, the
logical way to write it is
\begin{equation}
\begin{array}{rlc}
x & = & ...
\end{array}
\end{equation}
I suspect that this will produce the proper formatting.

When constructing the .aux file, LaTeX writes out captions as a single
line. A large caption will easily exceed the default maximal line
length of 500 characters (Unix TeX, web2c C version), especially if it
is the least bit mathematical. As a workaround, we have increased the
default value of the line buffer size up from 500 to a few thousands
(to allow for 1/3 of a mammoth page :-). Maybe someone can figure out
how to get LaTeX to break long captions...
Figure captions are written onto the .aux file so they can appearn in
the list of figures. A 500 character entry in the list of figures
isn't of much help to the reader, so there's no reason for writing it
on the .aux file. Read about the optional argument to the \caption
command.

I am trying to change the placement of footnotes when there is not
enough text to fill to the bottom of a page. In the example below I
force the figure to start at the top of the next page, there is now
white space that occurs on the first page. I would like LaTeX to
always flush footnotes to the bottom of the page, instead of putting
the footnote right after the text.
She would have obtained the desired result had she ended her incomplete
page with a \newpage or \clearpage command rather than a \pagebreak
command. Remember that \newpage and \pagebreak are analogous to
\newline and \linebreak, the latter being used only to help TeX
find better breaking points, not to prematurely end a page or line.
Leslie Lamport (or the typographer he consulted) seems to have gone to
a lot of trouble to design the various aspects of the standard LaTeX
styles as appropriate for various point sizes. However, I'm not clear
about the size of paper for which they were designed.
To avoid future problems, would it be possible for this information to
be put in comments in future editions of ART10.DOC, ... , BK12.DOC?
The positioning of the text area on the page is done assuming an 11 X
8.5 page size. (For example, that's the size for which single-sided
output will be horizontally centered and reasonably well positioned
vertically.) The values of \textwidth were chosen to put the maximum
amount of text on a line without sacrificing readability. This value
is independent of paper width; it should not be increased but can be
decreased to about 3 inches if desired for narrower paper. The value
of \textheight was chosen to provide a reasonable amount of text on an
11-inch high page, and give top and bottom margins that look reasonably
good with the side margins on 11 X 8.5 inch paper. However, the value
of \textheight is not critical. It can be increased if desired for
more economical use of paper,
People who mess with such document-style parameters as text width and
height should know what they're doing. The comments of the style
files don't seem like a proper place for a course on document design.

His question indicates that something impossible is happening--namely,
that the output produced by a figure caption depends upon the context
in which that figure appears. My guess is that in the two cases, the
captions were not the same because the figure number was wider in the
"real text" than in the small test file. Remember that a minipage
produces a piece of text that cannot be broken across lines.
