Anyone have a cross-reference program?
Message ID:

I'm new to PERL and I've been given a program to analyze - and it's BIG. I
need to change and add some variables. What might help me greatly is if I
could obtain a crossreference program that would tell me where all the
variables are defined and used. I could use a search in wordpad or etc. but
a crossreference would be ideal. Does anyone know where I might find one -
or at the least a program to list/sort variables by line number? Thank you!!
