software development tools

[Ramon F Herrera]

I am looking for a couple of programming aids at both ends of the
price/functionality spectrum: a public-domain program that will
take a set of C source files and tell me which function calls which,
in what line, etc.  On the other hand, I need some advice about
some comprehensive, commercial CASE tool set for C/Unix.

Any suggestions, pointers, etc. will be very much appreciated.

Please reply via E-mail.  Thanks in advance.

Ramon
