There are a couple of ways to find this. It should be listed in the running MV for z/OS PAS JESLOG. Like this:
BBDDA017I Common Storage Monitor(3.8.00) Service Point Attach
BBDDA017I MainView SYSPROG Svcs (3.8.00) Service Point Attach
BBDDA017I CMF MONITOR Online (6.0.00) Service Point Attach co
BBDDA017I MainView for USS (1.7.00) Service Point Attach comp
BBDDA017I MainView for z/OS (3.2.00) Service Point Attach com
Or you can go into PLEXMGR from the primary selection menu (option P) then on the command line type TGTGRP. Scroll down to you see MVMVS and then hit PF11 to scroll right. You should see:
The Ver and Rel Columns tell you the release and version.
Hope this helps,
Thanks, Fred!!! That is exactly what I was needing.
