1) But how would it be identified in the CL via a MONMSG?
It would be nice if some example someone could provide for this case.

The following will only work if PGMA raises an exception when it
fails.

DCL VAR(&GOOD) TYPE(*LGL)

CHGVAR VAR(&GOOD) VALUE('1')
CALL PGM(PGMA)
MONMSG MSGID(RXI0000 CPF0000 CPE0000 CPD0000 +
MCH0000) EXEC(DO)
CHGVAR VAR(&GOOD) VALUE('0')
ENDDO

IF COND(&GOOD) THEN(DO)
CALL PGM(PGMB)
ENDDO

2) How does Program A intentionally set that parameter value which CL

can

use to identify whether it 'OK' to go on and Call Program B or not ?

If PGMA does *NOT* raise an exception when it fails, then PGMA
must be passed a parameter which PGMA can set to indicate success or
failure. For example:

DCL VAR(&GOOD) TYPE(*LGL) VALUE('0')

CALL PGM(PGMA) PARM(&GOOD)

IF COND(&GOOD) THEN(DO)
CALL PGM(PGMB)
ENDDO


If sometimes PGMA raises an exception and sometimes it doesn't,
then you must combine both methods.
