RE: Termination of the entire Call stack

Hi
Joe, Scott, Bob,
Yup.. that's definetly a problem, i just implemented this method in the PSSR
, the problem is the *PSSR of B pick up the *ESCAPE message and displays our
custom error message screen, and when this ends, PGM A picks it up...and
does the same...and now my user would have to deal with three error screens
instead of one..:-)...
As of now I have no clue on how to detemine the the First Pgm in the Call
Stack, 
I will try killing the actgrp as suggested by Bob Cozzi i.e "call CEETREC ",
as there could be multiple *ACTGRPs within the call sequence..i am not too
sure...
I guess, I would decide on using a return parameter after all...as i don't
have too much time to try out things before the delivery....

Thanks for all the help and suggestion...all these would be archived and
stored for future reference..

Warm Regards
Denzil D'Souza

The answer is - it depends <grin>.

Do you know which program is at the top?  If so, you can send an escape
message directly to that program, which will in effect terminate the
entire stack.

SNDPGMMSG  MSGID(&MSGID) MSGF(&MSGF) MSGDTA(&MSGDTA) +
             TOPGMQ(*PRV (&PGM)) MSGTYPE(*ESCAPE)

This sends an escape message to the program that calls &PGM (which could
be a menu or the command line).  So, if you call A from the command
line, if program C encounters an error, it can send it back to A's
caller by specifying &PGM as "A", and the error will be returned to the
workstation.

The hard part sometimes is determining which program is the highest
level, especially if A is sometimes the top and B is sometimes the top.
