A tool I've discovered that would be very useful to have is one that would help you explore the ways in which a subroutine could get called.

For instance, using grep it is easy to locate lines where a method or subroutine is called. However, I also want to know the name of the subroutine that call is located in. And then I want to explore how that routine can get called, and so forth.

For my needs static analysis of the program text is sufficient.

Does anyone know of a tool which can help you explore code this way?
