Marc,

This would be doable if you were willing to open and read every
file referenced in the program.  Each of the /COPY members, display
file members, physical file members, printer file members, etc...

Build a huge list that would look, basically, the same way the 
variable list does at he end of a compile.  Where each variable is
declared and used (multi dimentional array would work).  Then it
would a simple matter of reading through your array and looking for
where a variable is defined and never referenced.

Hmm.. thinking on it though, wouldn't it be MUCH simpler to just
take the output from a compile and process that?  You already have
all the cross reference information you need in there nicely laid
out for you.  It tells you all the member names for each physical
file, all the variable names, where each is defined/referanced, etc...

Why reinvent the wheel?  In fact, I seem to recall, I could be 
mistaken, that you can compile without actually creating the program.
Have your program run a compile without building and then read the
spool file and process it.

Jim Langston
