John,
        Listen to your wife!  Spend all the time you want when you're 
100% again...

Tim,
        Here's a re-post of John's code...

In your *INZSR subroutine repeatedly call a CLP to retrieve the
program name of the caller.  You can "walk up the Stack" past the
programs(OS/400's that begin with "Q")  to the program you're looking for.

Just call the below program repeatedly(in a loop in your *INZSR),
First time pass your trigger program name as the &CALLED, and who ever
called your trigger will be returned in the &CALLER variable.  This will be a
"Q" OS/400 program.  Call the CLP again this time pass what was
returned the first time to find out who called him, and so on.  up the stack
till *EXT..

Stop when the program name(&CALLER) doesn't begin with a "Q".
That's the program you want..

PGM    &CALLER &CALLED

DCL   &CALLER  *CHAR  10
DCL   &CALLED  *CHAR  10
DCL   &M1KEY   *CHAR   4
DCL   &M1MDTA  *CHAR  80

SNDPGMMSG  MSG('TEST')  TOPGMQ(*PRV &CALLED) MSGTYPE(*RQS)
KEYVAR(&M1KEY)

RCVMSG   PGMQ(*PRV &CALLED)  MSGKEY(&M1KEY)  SENDER(&M1MDTA)

CHGVAR   &CALLER    %SST(&M1MDTA  56 10)

ENDPGM
