Ok. Use QMHSNDPM and specified the program name that I want to check on
the stack entry parameter works. I get CPF2479 when program is not in
the stack. (Note: Instead of *DIAG message type, I use *RQS message
type and do a QMHRCVPM to remove it.) Not sure if this method is faster
than QWVRCSTK or not. But it sound like it should.
