Calling Hierarchy Tool

[Joeseph Lerner]

Hi,

  I was really hoping someone would have the source for a tool that would 
enable me to determine the calling hierarchy in a large piece of software
written in C that I have been modidfying (I've been running it on a 
DEC 5100 machine).

				Thanks in advance,
				    Joe Lerner
