PASSPGM
The PASSPGM option makes IDF pass program interruptions that are not the result of a PER event to the CMS, z/OS®, or z/VSE® program interrupt handler. Used for debugging exit routines.
Warning: If the target program has not
activated an exit routine to trap the interrupt, IDF abends. You may
need to re-IPL CMS or logon to TSO again following the debugging session.
On z/VSE,
PASSPGM occurs
immediately on STXIT PC entry. If the STXIT is not present, then IDF
traps the program check.
