     Right, that's exactly what went through my mind too.  Guess what PDC
prolog is probably written in ... :-)
     Since I posted the original article, I have bit the bullet and tried
the example they gave on pgs. 78-79 of the reference manual.  It's not as
bad as it sounds; although the solution is not to use any global domain or
databases.  Unfortunately, you can't get around the include file for the
global predicates...
     I would imagine that not using any global domains, if you would have
redundant declarations in different files, this would increase the size of
the symbol table?
     I just hope PDC does improve the project facility, among other things
in their next release.
