The SNAP macro is simply a wrapper for the PDUMP macro. IIRC the parameters given to the SNAP macro are labels in the program whereas the PDUMP macro expects addresses in storage.
Hello!
That's an excellent question. I don't know. Dave W might,. There are
other books on the subject, two of them were written by Jeff Savit.
He's an old friend of VM, and wrote those two whilst actually managing
the OS for one of the victims of the Great Recession. I can list them,
but I can rather do that in a completely different thread. The other
was written by Phil Smith III and Gabe Goldberg. It's on VM/ESA but
should provide some good ideas.
If you're running DOS under VM then the book written by the Professors
Yarnish concerning Assembly programming on OS and DOS for S/360 and
S/370 will work.
I seem to recall that many good libraries have books stacked up on the subject.
