I use SUN's SCCS version control system for my LaTeX documents. SCCS has a
program called 'what', which is used to check from what versions of files a
program is made. This works, since SCCS's get command (to get specific
version of file) expands name, version number and date to the file.

I thought, that it would be nice to use "what" on dvi-files, so I use
following text on my LaTeX files:



{%
\catcode`\#=11%
\special{what: %A%\#}%
}%

Point is, SCCS's get expands %A% to name of file, plus version number with
some special characters around. Since I use \special, it is inserted verbatim
to dvi-file and "what" can find it there. 

BUT, dvips and dvi2ps (dvi printing programs for PostScript) think, that
'what:' is for them and they insert contents of the file mentioned in
\special to PostScript file and LaserWriter does not understand LaTeX!. I
thought Knuth said in TeXBook, that \special's first word says for which
program \special is for ??

Can you help me ?
