You can call an RPG service procedure from a CL program to get the
subsystem status. The following is jsut such an RPG service procedure
which I wrote.

That led me to something much simpler:


DCL VAR(&RCVR) TYPE(*CHAR) LEN(38)
DCL VAR(&RCVL) TYPE(*INT) LEN(4) VALUE(38)
DCL VAR(&ERROR) TYPE(*CHAR) LEN(8) +
VALUE(X'0000000000000000')

CALL PGM(QWDRSBSD) PARM(&RCVR &RCVL 'SBSI0100' +
'BAR FOO ' &ERROR)

IF COND(%SST(&RCVR 29 10) *EQ '*INACTIVE ') +
THEN(STRSBS SBSD(FOO/BAR))

More elegant than STRSBS with a MONMSG, and it gives one a choice of how to respond to the "*INACTIVE" status, either starting the subsystem, or falling back on QINTER or some such.
