Thanks! I didn't even think to read that section of the manual. "Tunnel vision" on the APF section. My bad. Now I really wonder why the ALLOCATE verb even exists. I guess I can understand about not allocating an existing dataset, due to it possibly be in use by another job. Perhaps it's for output via the OUTFILE subparameter. Hum, really need to think about that.
