Our lab uses TeX 2.95 from labrea.stanford.edu (./tex/unix). Would someone tell us where we could find the UNIX/C source for TeX 3.0? Also, I do not understand the implications of the new virtual font convention. Does there exist somewhere an explanation of what virtual fonts are, and what practical changes must be made to accommodate them? Are TFM and PK formats obsolete or intermediate now?

You can get more information by sending e-mail to elisabete@max.acs.washington.edu. Reason #452 for ordering the tape rather than FTPing: Elisabeth Tachikawa can answer questions about any problems you encounter installing the tape (including such things as "why isn't the online display support working on my DECstatio?" etc.) >Also, I do not understand the implications of the new virtual font >convention.

Reason #23 for joing TUG: You receive TUGboat which contains many informative articles on TeX and related software. TUGboat 11#1 contained an article by Donald Knuth explaining the point behind virtual fonts. Since you doubtless don't have a copy, I'll summarize. (1) VF allows one to make "composite fonts" where a single TeX character can represent any sequence of DVI commands. Thus, it is possible to do things like (a) remap the coding of a font, (b) construct accented characters from a character and accent or (c) almost anything else one can imagine. (2) To use the VF features, you need to have a driver that knows about virtual fonts. As far as I know only Tom Rokicki's dvips 5.x and the ArborText drivers can handle this at present (can anybody name others?). In the near future, a program DVIcopy will be released which will convert a DVI file referencing VF fonts to a VF-free DVI file. -dh The TeX Users Group can be reached at: TeX Users Group P.O.
