Are you looking to set the usermax to an appropriate value via
automation, or simply trying to determine the current value??
In the CVT there is a pointer to the TCAST, CVTTCASP is at offset 1012
(x'3F4') in the CVT.
I believe that TCASUMAX is a 2 byte field at offset 6 in the TCAST. I
think that you will need to be authorized to display it!!!

Subject: Determine TSO USERMAX?

Hi!
In an effort to improve automation, I am looking for a method to determine
TSO USERMAX other than issuing console commands. Blowing the dust off old
documentation, "z/OS V1R10.0 Comm Svr: SNA Data Areas Volume 1", I found
"TCASUMAX" in "Terminal Control Address Space Table" (TCAST). Neat. This
would seem to fill the need. However, it appears SNA Data Areas are no
longer being published for modern z operating systems to verify this
information is still available. Does anyone know of a way to get this
information?
