Subject: TeX, how to detect already defined control sequences

Hello,

I would like to know if there is a way, in TeX, to test for
the existence of a control sequence.

What I want to do is to programmatically detect if a macro
has already been defined.

I devised this (ugly) piece of code:

        \def\MYMACRO{anything}
        \ifx\MYMACRO\UNDEFINED
             The macro is {\it not\/} defined
        \else
             The macro {\it is\/} defined
        \fi

It works, provided that the dummy macro \UNDEFINED is
*really* undefined!

There must be a more reliable (and elegant!) way to do the
same thing. Can you give me any hint?
Thanks in advance.

From:    David.Osborne@nottingham.ac.uk
Subject: TeXhax/UKTeX merger opinions

Following my note about merging the TeXhax and UKTeX Digests
(TeXhax V94 #10, UKTeX V94 #42), I received 12 responses, all
in favour of the merger.  There were two reservations expressed:

- - frequency of the new TeXhax... weekly was felt by a couple of
  people to be too often
- - one person requested that the digest be given a new name

One of the advantages of increased frequency is that questions
can be answered and announcements made in a more timely fashion.
This has always been one of the "advantages" of the UKTeX Digest
which I'd like to carry over into the new, merged digest.
However, after we've had a few issues, if lots of people feel
strongly that a weekly digest is hitting their mailbox too often,
please let me know and we could move to, perhaps, two-weekly issues.

As for names, well, I felt it would be less confusing to keep the
name of the "elder" publication, which is mentioned in many online
locations and Internet list-of-lists (e.g., Meckler's "On Internet 94").

If you have any views on any of this, please let me know.

I have two copies of the 1994 EuroTeX proceedings for sale at DM15-00 plus
postage; if I receive more requests than I have copies, I will endeavour
to order further copies from Poland.

\section TeX Implementations for Small Computers

\subsection PC and Mac disks

    From January 1994 the UK TeX Users' Group is distributing an
    emTeX kit for PCs, and an OzTeX kit for Macintosh. The cost
    covers copying and postage costs, and the shareware fee for
    OzTeX.  Each set costs \pounds30, and is available from
    Peter Abbott, 1 Eymore Close, Selly Oak, Birmingham B29 4LB.
    Cheques must be payable to `UKTUG'. Please note that this
    service **is available to UKTUG members only.**

    Each set comes with an installation guide, and (at least)
    full TeX and Metafont, a previewer, a PostScript driver, and
    CM fonts. Two update disks a year will be sent out
    automatically, with the current version of LaTeXe, and other
    goodies. A subscription service will be available for
    subsequent years. In addition, subscribers can request up to
    3 disks a year with any material from the CTAN archives, but
    this will be supplied `as is', without instructions.

    OzTeX and emTeX are also available on disk from TeX Users Group;
    mail TUG for details.
