Re: Recursive program calling

Yes, there is an easy trick. Send a message to the previous program on the
stack, receive this message in your program and the sender information
contains the caller. check the command for more info.

Here is some CL source to get you going.

            pgm parm(&CALL &PGM)

            SNDPGMMSG  MSG('knock knock') TOPGMQ(*PRV &CALL) +
                         KEYVAR(&KEYVAR)
            RCVMSG     MSGKEY(&KEYVAR) SENDER(&SENDER)
            CHGVAR     VAR(&PGM) VALUE(%SST(&SENDER 56 10))

Regards,

Wim
