Re: Calling CBLLE-procedures from a RPGLE-pgm?

Is the COBOL program called many times? the reason I ask, is a
performance problem I was with OPB where RPG called several COBOL
programs repeatedly (thousands of times per hour). Performance was
terrible, because of COBOL environment ending after each call. I placed
a COBOL program at the top of the program stack, then used it to simply
call what was the first RPG program in the stack. Tis resulted in the
job running in 17 minutes, instead of 11 HOURS.

I do not think this is a problem with a bound ILE program, but maybe
someone else knows.
