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.

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. ~~David Osborne (TeXhax Digest moderator) ------------------------------ Date: Fri, 16 Dec 1994 12:20:39 -0000 From: CHAA006@vax.rhbnc.ac.uk Subject: Limited number of copies of the EuroTeX '94 Proceedings available 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.

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. \subsection TeX for the Atari ST Enquiries for TeX for the Atari ST etc. can be directed to: The Fast Club, 7 Musters Road, Nottingham NG2 7PP.
