+Subject: BLUe's Format goes public. Beta-testers asked.
+
+The last time I worked hard on BLUe's Format and it has ripened a lot.
+I introduced BLUe's Format altready at CyrTUG 94 and EuroTeX 94, but
+I schedule it to go public at EuroTeX 95 (and CyrTUG 95), because it has
+ripened and the user's guide Publishing with TeX is in the polishing
+phase.
+
+Spring is scheduled to let friendly TeXies look at it and comment on it,
+bete-testing so to say.
+
+The beta-version will be distributed also on next NTG's CD-ROM.
+
+The user's guide is in English, physically and logically thin,
+and will be translated into Russian.
+
+The PWT guide will be offered to the CWI, for their CWI sylllabi series,
+and also to NTG, to be rleased as a MAPS special.
+
+Best wishes, ---Kees---

+I can't really help you, Alan. The archive (when it used to be at
+Aston) had binaries for all sorts of systems; amongst those for VAX/VMS
+were .OBJ files for nearly everything, including DVItoLN03. These
+binaries were VVencoded, so that they could be mailed anywhere, as well
+as being FTPable. Some binaries existed as separate files, but most
+were in bundles, as BACKUP save_sets.
+
+It seems that these files were lost when the archive was moved to a Unix
+machine at Cambridge (at least, I can't find them there now). I _have_
+found some binaries, which _don't_ include DVItoLN03, but those that are
+there are of VERY LITTLE UTILITY: note for archivists --- it's pointless
+keeping .EXE images, because they may not be linked with the same
+version of the shareable libraries as on the target machine. OTOH, .OBJ
+files, either VVencoded (under VMS) or zipped (also under VMS) _are_
+acceptable, and remarkably portable. (I saw that there is at least one
+zip file of .OBJs, but I'd guess that it doesn't include what Alan
+wants.)
+
+I'm copying this reply to TeXhax; hopefully someone who is more
+conversant with the present-day layout of the archive than I am can
+assist Alan. It may be that I'm mistaken, and that the files wanted
+_are_ still in the archive: if so, I can only say that the layout
+nowadays is non-intuitive.

+Subject: DOS color dvi previewer
+
+I am looking for a DOS/Windows dvi previewer that supports the
+color packages and the virtual fonts. I acquired a commercial version
+of Tex/Latex from PCTEX, after having read their publicity on the
+compatibility with Latex2e and packages. It is far from being compatible.
+So please if you have this information, We will appreciate.

+Subject: Commands for page selection in Ghostscript
+
+I wonder if anyone can shed light on this. In the ftp site at:
+
+src.doc.ic.ac.uk/0-Most-packages/uk-tex/support/psview
+
+There is what appears to be some utility and batch files for running
+ghostscript with keystrokes for selection of pages, magnification,
+translations etc.
+
+These have been written by P.Pianowski and B.Jackowski and were
+presented at the 8th EuroTex Conference 1994.
+
+My problem is that I have tried to run ghostscript (MS-DOS) with these command
+procedures with no success. The "batch files" do not appear to be DOS.
+Does anyone have any more information on this stuff, or know how/where I
+can contact the authors of the work?
+
+Many thanks

+I would like to know if there is a way, in TeX, to test for
+the existence of a control sequence. [...]
+
+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?
+- ----------------------------------------------------------------------
+
+Well, Paolo has written pretty much what I would have done in the
+same situation, except that I would use the lowercase form of the
+control sequence \undefined, and I would take the constant code out
+the the conditional, like so
+ The macro
+ \ifx\mymacro\undefined
+ is {\it not\/}
+ \else
+ {\it is\/}
+ \fi
+ defined.
+
+The optimisation of placing the italic correction \/ outside the
+conditional is hardly worth bothering with, and likely to cause
+errors later.
+
+If you look up \undefined in the TeXbook you will be pointed to
+page 384. It is almost a pukka control sequence of plain. And like
+any other such control sequence, if you change its meaning you will
+cause things to mess up.
+
+What I find most interesting about this question is the doubt the
+author expresses about his own answer. It is not ugly. It is just
+as it should be. (There is one wrinkle. Perhaps he would prefer to
+have \und@fin@d?)
+
+By the way, the LaTeX \@ifundefined construction is a waste of time,
+by which I mean that
+ \expandafter \ifx \csname #1\endcsname \relax
+ etc \else etc
+ \fi
+will execute much quicker than
+ \@ifundefined{#1} etc
+and this is because the former code takes TeX straight to what needs
+to be done.

+Subject: EDMAC and line numbering
+
+As suggested in TeXhax 95/04, I have looked at the EDMAC package for
+numbering lines. It looks like will certainly do what I ask, and
+more, for most people. Unfortunately, however, it contains an
+undocumented (at least, I _think_ it's undocumented) constraint that
+renders it not useful for my purposes: one cannot use a redefined
+\par.
+
+So... does anyone know of any other packages that might permit me to
+have my cake and eat it too, in that I can use my redefined \par and
+still get line numbers in the margins?
+
+If I have to, I suppose I'll try hacking EDMAC to do the job I want,
+but I'd much rather not, because I'll probably break three things for
+everything I "fix".
