What you're looking for is called 'yyref', and was published on
comp.sources.unix. I've fixed a few of the bugs in it and would be
glad to send you a copy of the repaired version (or put it up on the
archive here, if there's enough interest).


If you'd rather have the original, you should be able to get it from
the comp.sources.unix archive on j.cc.purdue.edu in
comp.sources.unix/volume6/v06i051.


Cheers,
