program cross reference listing

[Calvin H. Vu]

We will have a Fortran source listing option in the next release which
gives you variable/function/subroutine/parameter usages/references.  
It doesn't give you just the function/subroutine cross reference 
though.

cxref(1) seems to be what you want for C.  If there are problems with it
you can report them to the Hotline to get them fixed rather than giving up
on it.  That tool is too simple to have any serious bugs.  Probably you only
missed some -D definitions for the cpp(1) preprocessor.
