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!!!

[[ SEI WARNING *** This email was sent from an external source. Do not open attachments or click on links from unknown or suspicious senders. *** ]] 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? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
