Unless I misunderstand the thought behind "I think CMAP (a commercial
product) used to do this sort of thing, but VM/ESA is no longer supported
by most ISVs, so I doubt it is still available."
CMAP/XA is indeed still available. It's now marketed (barely) and
supported by Macro4 - it's not easy to find on their web site, look at:
http://www.macro4.com/support/productlevels/vm-esa/cmap.html
But even so, I don't *think* it addresses the questions asked here.
Basically we use it to tell who is executing which "monitored" commands.
But it may do more than we ask of it.

As I said earlier, this is possible for MACLIBs because they are printable
human-readable text. For TXTLIBs or LOADLIBs, the only comparison possible
using the native tools is a bit-by-bit comparison of the contents of the
members, which isn't really very useful.

It might help to step back and tell us what the bigger problem you're
trying
to solve is. I'm guessing that you're trying to find out what version of a
library is being used for applications, and remove some duplicate copies.
Is
that guess correct?
In the case of TXTLIBs, address symbol resolution and such are resolved at
the time you LOAD the module into storage, so there really isn't any such
usage information *in* the module other than the external symbol table,
which doesn't tell you much more than what the MAP option does on the *LIB
commands. LOADLIBs are similar in behavior.
You could write a modification to the CMS LOAD command that recorded the
information it used when linking the application, but that's a fairly
major
project, and won't catch already-compiled modules - you'd have to rebuild
all your MODULE files for it to be effective. You'd also have to get deep
into the OS simulation stuff to catch things used there.
I think CMAP (a commercial product) used to do this sort of thing, but
VM/ESA is no longer supported by most ISVs, so I doubt it is still
available.
