Is there anyway to find out just the routine that invoked you. In other words:
Sub A -> Sub B
can B find out that Sub A called it? IBM mainframe using their Fortran G could do it but it took an assembly program to do it but it was not hard. Does ivf use a particular calling method and is there a register/accumulator that keeps the return address or is some part of the stack that has a pattern that can be searched?
I have a routine that is called by one of 15 different routines and I would really like to find out which one invokes it. I care not what other routines call that one.
