This can be done trought programming. I am including a program that we use here
for that. (I apologize for the fact that all comments are in french, we are a
french canadian company).
The first parameter is how up in the call stack you want to go (1 in your case)
The second parameter is the name of the program in the position of the call
stack you requested.
By the way, this program works in both ILE and OPM mode

Hi All,
In one of our application, we have an RPG Program say PGMR which is called
by a CL Program say PGMCL. If i want to ensure that PGMR is called by PGMCL
alone and not directly from command line or from any other program, how will
i check this in the called Program ie PGMR..
Thanx in advance
Shepherd P Chacko
Robert Bosch,
India.
