Defining negotiation limits and displaying session limits

The DEFINE/DISPLAY control block (ISTSLD) is used to:

Specify defined negotiation limits that VTAM® uses in CNOS negotiation.
Display CNOS session limits that are currently in effect.

You can add defined negotiation limits to the LU-mode table using the APPCCMD CONTROL=OPRCNTL, QUALIFY=DEFINE macroinstruction and specifying the DEFINE control block where the values are set.

You can display the values currently being used for CNOS negotiations using the APPCCMD CONTROL=OPRCNTL, QUALIFY=DISPLAY macroinstruction to specify the DISPLAY control block where the values are returned.
