RE: Who pulled the trigger?

[Peter Connell <peterc@xxxxxxxxxxxxx>]

Sue,
The name, but not the library, of a calling program can be determined by
sending a message, via SNDPGMMSG, back up the call stack and then retrieving
that same message, via RCVMSG and examining the contents of the SENDER to
obtain the program name. However, since a trigger program is actually called
by a system pgm, the user program being resolved is a few levels back up the
stack. If you don't wish to have a generic method that works for all
triggers, you can cause the trigger to fire, in debug mode, and look at the
pgm stack to determine the name of the system pgm before which your user pgm
appears in the stack. This would then be the pgm to which you would send the
message. Here is some sample CL code

DCL        VAR(&KEYVAR) TYPE(*CHAR) LEN(4)             
DCL        VAR(&SENDER) TYPE(*CHAR) LEN(80)            
DCL        VAR(&PGMQ) TYPE(*CHAR) LEN(10)              
                                                       
SNDPGMMSG  MSGID(CPI2401) MSGF(QCPFMSG) TOPGMQ(*PRV (???SYSPGM??)) + 
             KEYVAR(&KEYVAR)                           
RCVMSG     PGMQ(*PRV) MSGKEY(&KEYVAR) SENDER(&SENDER)  
CHGVAR     VAR(&PGMQ) VALUE(%SST(&SENDER 56 10))

Cheers, Peter

Subject: Who pulled the trigger?


This question has been asked on this forum recently, but I didn't have the
foresight to save the responses. (duh!) 

Can any of you gurus tell me how I can determine what program caused the
trigger to fire?  Is it even possible?  

Thanks
Sue
