1. Contact your site support group and ask them. This is the type of data they have to know and they should be your FIRST point of reference -- not a forum.

2. If you have access to console commands (and not everyone does), D IPLINFO will return a display with the z/OS version.

If you go to the ISPF Dialog Test menu (Option 7) and look at the Variables (Option 7.3) you'll find a few general systems variables:

ZENVIR - Environment Description
ZOS390RL - Indicates the z/OS release running on your system.

Thank you both!

I didn't know 7.3, but it seems interesting :)

Many shops put this type of information in the ISPF Primary Options Menu, typically at the top right of the screen.

It is also in several CLIST and Rexx variables, which you find in several refrences like this one and this one.

Knowing a lot of new methods now. The option 7.3 and the TSO IPLVCALL STATUS are interesting.
I have another method , under SDSF, issue 'WHO' then you could get the version of zOS too.

Enter the following zOS command from the console, SDSF, etc :

D IPLINFO

The following output will be returned, showing the zOS version etc:

IEE254I 05.25.12 IPLINFO DISPLAY 108
SYSTEM IPLED AT 20.53.33 ON 11/12/2018
