Finding where an escape message came from

Hello,

I would like to know if there is a way to find where a monitored escape 
message came from?

I have a program with something along those lines.

monitor; 
     myProc();
on-error; 
     // Error logging logic.
endmon; 

The procedure 'myProc' calls other procedures and even other programs. 
Sometimes, one of the called procedures or programs will send an escape 
message.  I would like to write in my log file the origin of this escape 
message (program name, module name, procedure name, specification...).

I have searched the mailing list archive, and found some interesting 
threads (i.e., http://archive.midrange.com/rpg400-l/200307/msg00373.html 
), but I could not quite find what I am looking for.

Is what I am trying to do impossible with the monitor opcode?  Do I have 
to use the ILE Condition Handler API no matter what?

Thanks in advance.
