a psfig/ditroff mystery

[Ed Arnold]

I have a psfig/ditroff mystery in need of a solution.

About 3 months ago, I posted an inquiry about what software was
available to merge postscript figures into ditroff documents.  The
responses I received said to use either psfig, available via ftp
from linc.cis.upenn.edu, or Elan Computer Group's "eroff".

I tried psfig first, since we already have Transcript 2.2 and ditroff
source.  The ditroff source we have was purchased in 1989.  The tape
does not give a version number, but the paperwork sent to AT&T
specified "DWB 2.0".  Since the psfig documentation says you need DWB
2.0 or later (because psfig uses the "\X" construct), I figured we
were OK.

After installing psfig, running the psfig documentation produced a
*mess* on paper and a core dump from ditroff.  Looking thru the "UNIX
System V Documentor's Workbench Software Release 2.0, Technical
Discussion and Reference Manual", specifically the TROFF(5) man page
which describes what the output language of ditroff means, I found
there was NO "x X string" mentioned as part of the output.  Sure 'nuff,
typing "\X'string'\n" at ditroff did not result in "x X string\n" in
the output.

The question is: did AT&T *really* make this modification to ditroff,
or is this an urban legend?  Or perhaps we ordered 2.0, but got
something older instead?  If AT&T did not make this modification, does
anybody out there have a patch which will add this feature to n1.c,
version 1.5, before I burn the time to do it myself?

Here is a list of the SCCS ID keywords from files in the troff
subdirectory of the DWB tape received from AT&T, and a "cpio -ictv"
listing of the files in the troff subdir.  If anyone who is
successfully using psfig can tell me how this compares with their
ditroff, I would appreciate it.
