Hi Dave,

if you are not on V5R1M0 you can use a CL-Program to determine the caller
program:

             PGM        PARM(&P$CALLER           +
                             &P$CALLED )

             DCL        VAR(&P$CALLER) TYPE(*CHAR) LEN(10)
             DCL        VAR(&P$CALLED) TYPE(*CHAR) LEN(10)

             DCL        VAR(&MSGKEY)   TYPE(*CHAR) LEN(4)
             DCL        VAR(&SENDER)   TYPE(*CHAR) LEN(80)

             SNDPGMMSG  MSG('TEST') TOPGMQ(*PRV (&P$CALLED)) +
                          MSGTYPE(*RQS) KEYVAR(&MSGKEY)

             RCVMSG     PGMQ(*PRV (&P$CALLED)) MSGKEY(&MSGKEY) +
                          SENDER(&SENDER)

             CHGVAR     VAR(&P$CALLER) VALUE(%SST(&SENDER 56 10))

ENDE:        ENDPGM

Using this program it's even possible to loop through the whole call stack.
