The reason for lists appearing the way they do in the theorem environment
is due to the way that LaTeX handles lists. First, you should know that
lists, theorems, quotations, and numerous other environments are what
LaTeX calls a "displayed" paragraph. A displayed paragraph should be used
in only the three following ways:
1) in the middle of another paragraph (displayed or otherwise)
2) at the end of another paragraph
3) as a paragraph by itself.
Inside a list, some special things are done with a displayed paragraph:
item number 3 above is no longer valid immediately after an \item command.
In order to have a displayed paragraph as a paragraph by itself in a list
the most recent \item must have some text following it. This makes sense
if you think about it since you generally won't want a list to look like
1)
o Stuff
o Stuff
2) More stuff
In fact, if we were to type
\begin{enumerate}
\item
\begin{itemize}
\item stuff
\item stuff
\end{itemize}
\item More stuff
\end{enumerate}
LaTeX will produce
1) o stuff
o stuff
2) More stuff
So how does this apply to theorems? Well in fact the theorem environment
(along with center, flushleft, flushright, quote, etc. (see the LaTeX manual
under trivlist for details)) is actually a special case of a list environment.
The label "Theorem 1" is passed as the optional argument to \item (which is
the only item in the list) and so your list ends up being typeset as you
described. The "correct" way to deal with the problem is to include some
text before the list in the theorem. If you think about it, you'll realize
that this is actually good style, since a list by itself generally isn't
going to do a good job of conveying information, and a brief introductory
paragraph is the best way of dealing with this. (If you're ever bored,
try looking through every book you own and see if you can find a list that
begins a paragraph or a theorem-type environment that consists only of a
list. I doubt that any reputable publisher would allow that in a text.)

Re Mac crash when overloaded (MN Ullah)
well, i'm afraid the problem is with the Mac, or rather, the 1 Mbyte
memory. what you are asking the Mac to do is run TeXtures concurrently.
i.e. consume lots and lots of memory. what you should be doing is either,
buying more memory, or, instead of clicking on the window, editing and
re-typesetting, do the following: click on the exit button, which drops you
into the editor, but `closes down' the typesetting part, make your
correction, then typeset again. even if you put the memory up dramatically,
by the time you had typeset/corrected three or four times by your present
approach, you would be back in the same situation. is this clear?

Subject: \pounds in LaTeX
cc: lamport@COM.DEC.DECWRL
Well, I checked the definition of \pounds and sure enough, it will
generate a $ sign in math mode. Let's look at it and see why:
\def\pounds{{\it \char'44}}
In math mode, \char does *not* produce the character specified by the
code indicated in the current font, primarily because TeX ignores
the current font. Instead, it looks for the mathcode for the character
in question and executes that, thus giving a Roman dollar sign as
one would expect had the \it not been there at all (see lplain.tex for
the mathcode definitions).
The simplest fix would be to replace this definition with
\def\pounds{\mbox{\it \char'44}}
But this won't permit a scriptsize pound sign in math mode. A better
fix might be to have \pounds defined as follows:
\def\pounds{\protect\ppounds}
\def\ppounds{\ifmmode\mathchar"4124\else{\it \char'44}\fi}
I haven't tested this last definition, so there might be some minor
glitches in it.

A copy of this note has been sent to Leslie Lamport so he can decide whether
it's worthwhile fixing this in a future release of LaTeX.

From: FPS@UK.AC.IMPERIAL.CC.VAXA
An interesting LaTeX feature:
If you create a temporary environment which includes a command like
\renewcommand{\rm}{\smallrm} rather predictably, this has side effects. The
killer is that the page numbering may adopt the \smallrm style, depending
on whether you were using the environment at the time of asynchronous page
build (which of course may be a long way from where you think it is). I
guess this is why TeX uses \tenrm in its output routine, rather than \rm.
I assume this is a well known feature to all you LaTeX-hackers: how do you
get round it? (And please, not the LL solution ``you shouldn't be doing
that anyway, see page XXX of the manual''.)

the fonts could be bought from Letraset. Was I imagining this? Does

Roger --- the latest version of SB-TeX in the archive is SB08TeX.Arc; it was
FTP'd using /CODE=FAST (VMS:VMS), and can therefore only be retrieved by another
VMS site, so far as I know. If you can get it back to a VAX, you should then
Kermit it to your PC using "SET FILE TYPE BINARY". The Archive maintenance group
are investigating OS-independent ways of storing all such files. There exists a
much later version, SB15TeX, but it is not yet available for general release.
Keith --- The *.CH files are copyright Kellerman & Smith, as is the SVI* code.

Subject: INIMF bug cured, missing VMS change-files, MF bug found...
From: pla@uk.ac.ed.cs.tardis
After a number of mistakes, I brought MF.WEB up to version 1.7 but still
INIMF crashed. I tried compiling and linking with the symbolic debugger
option, only to find that the VMS linker does not accept the debug option
on object files that have compiler warnings - ready_already being the
guilty party. I am not too fluent in Pascal, so it took a little while to
work out that the test for ready_already can be removed since it doesn't
apply to VMS (can't dump a running image). With that out of the way, I
found out why INIMF crashes on my system, and why nobody out there helped
me with this problem - they don't have it! The change file defines the
pool file as mf$bases:inimf.poo. The VMS version of MF cunningly
interrogates the operating system for the full translation of mf$bases for
later use (by inimf - not mf), and gets (because my machine is clustered
and because I used rooted directory syntax in my definition)
zaphod$dua0:[public.tex.][formats]mf.poo;1 which is two characters too long
for the file_name_size of 40!!!
Moving the whole lot to a directory with a shorter name fixes it, as does
defining mf$bases with a TRANSLATION_ATTRIBUTE of CONCEALED. However, it
seems likely that the problem with MF and elvish that I mentioned in
UKTEX89.08 is down to the same cause; when I ran it interactively it was on
the same node as the disk with the elvish sources so the file name would be
DUA0:[public...]tincoma; when I submitted it as a batch job, it was to
another node, and the file would have been zaphod$dua0:[public...]tincoma -
again over 40 characters.
The fix is simple since file_name_size appears in inimf.ch and mf.ch (it
isn't altered though) - change it to from 40 to 250. Although the file
names are currently padded with spaces to 40 chars, VMS Pascal will extend
them to 250 characters automatically, otherwise this change would involve
digging out everywhere a file name is used.
Since I wanted to create .PK files, I tried to get GFTOPK working, but
could find no change file in the tapes I have. I obtained a current copy
of the archive directory and discovered that not only is VMS GFTOPK.CH not
there, but that the PD VMS change files seem to have been thrown out when
the K & S stuff was removed (though there seems to be the odd K & S .CLD
file and VIRxxx.EXE left). In the end I settled for GFTOPXL followed by
PXTOPK.
I then incorporated the write-white mods which I had dug out of an old
TeXHaX (not TeXMaG as I stated previously) and the mode_defs for a Ricoh
4080 which I believe is the engine in an LN03, made appropriate local
changes to the Sauter command procedures (includes removing reference to
sauter.mf because the write-white mods include the augmented font-header)
and set things in motion. The font build is 98% complete, but I have had
some crashes: GFTOPXL cannot cope with CMINCH at \magstep3, CMITT10,
CMTCSC10 and CMTT10 (but not 8 or 9 or 12) all crash with bad pos at
\magstep2, the message being:
! bad pos.
<to be read again>
;
pos->...urrentbreadth:errmessage"bad pos";
fi.fi(x(SUFFIX2)r-x(SUFFIX2...
1.97 ...up crisp.nib; pos1(shaved_stem,90)
; pos2(hair,0);
?
Is this a known problem with, I hope, a known fix (which I hope someone
will tell me about) or have I done something wrong somewhere?
Graham Rule at Edinburgh University (UNIX user) contacted me and said he would
try and find the person who looks after the VMS side of things to save me
having to incorporate the changes to MF.WEB and TEX.WEB by hand (I'd just
finished the MF ones), but discovered that whoever it was had left six months
ago. Peter Ileive of Memex (also UNIX user) said he could write tapes VMS
understands and so I received updated WEBs, but of course no change files.
Preliminary tests of the write-white fonts and UKLN03 (I was using Rose's
DVI2LN3 V10) seem to give encouraging results, though there seems to be
some loss of subtlety to the cursive strokes.
To return to rnototex, the initialisation file has LIT as a synonym for
LITERAL, whereas it should be LT.
Next week, I'll have a go at updating TeX...

Subject: Textures on 1MB Mac
M.N. Ullah asks about Textures running out of memory. This will
happen when trying to typeset unless you have something very close
to a virgin system; Textures seems to need about 870K of free memory
if it is not to run out.
You can check the memory available using "About the Finder" on the
Apple menu. A typical figure will be under 800K if you have goodies
like Macromaker, TOPS, ShieldINIT,... in your system folder.
But there is a very nice way to keep such goodies, and still use
Textures (without which we could not live in Leeds) : you use a
program called "Blesser", which allows you to have more than one
system folder on a hard disc, and to determine which one will be
used on next startup (which will be "blessed", hence the name).
So you have one system with no extras at all (for Textures) and another
with all your networking, virus detectives, etc., for general use.
(Of course another way out is to expand to 2MB memory...)
Blesser is freeware, and Larry Siebenmann includes it with recent
distributions of Sweet-teX; I think it is in the Mac archives, but
it may be worth having in the Aston archive.
