(snip)


IBM OS/360 and successor such as MVS keep the ESD (external symbol
dictionary) in the load module. It is, then, fairly easy to generate
a call tree from a load module if one wanted to.


Some unix linkers put some symbols in for debugging, so in that case
it might be possible to do some external symbol tracing.


I think you need to explain the problem in a little
more detail.

[These days most Unix programs are dynamically linked which means that
they have all the external symbols in the load module. But I agree
that this problem needs a better definition. -John]
