Passing user-defined data to installation-wide exit routines

You can pass user-defined data to an exit with the MODIFY EXIT,PARMS= command. The following exit routines support this function:

ISTCMMND: Command verification exit routine
ISTEXCGR: Generic resource resolution exit routine
ISTEXCPM: Performance monitor exit routine
ISTEXCUV: USERVAR exit routine

User-defined data can be passed to the exit to allow the exit to tailor its processing. See the description of the exit routine for how to access the data from the exit.
