Freeware: Rexx - VSMAP

VSMAP is a REXX exec that displays the OS/390 (MVS) Virtual Storage Map. It obtains the areas in an in-line subroutine called get_vsmap which can be "borrowed" very easily.

VSMAP also includes my updated get_smfid subroutine which is updated to work in batch REXX.

I know what you're thinking: Omegamon, SHOWMVS, RMF, etc. also display the Virtual Storage Map, why Yet Another VSMAP. I wrote this for the get_vsmap subroutine that I plan to use in other REXX execs.

If you want more information on the MVS memory model, see VSM technical concepts on IBM's OS/390 web site.
