&SYSPROMPT

&SYSPROMPT indicates whether the CONTROL statement's PROMPT or NOPROMPT option is active. The value ON indicates that CONTROL PROMPT is active, and TSO/E commands in the CLIST can prompt the terminal for input. OFF indicates that CONTROL NOPROMPT is active, and TSO/E commands cannot prompt the terminal.

Your CLISTs can use &SYSPROMPT to test which option is active, or change the option. For example, if you want the CLIST to allow prompting from the LISTDS command only, you can code:

SET &SYSPROMPT = ON
LISTDS
SET &SYSPROMPT = OFF
