It is not a 0C4, but a PIC 4. 0C4 is not an interruption, but the abend code that MVS produces when it is unable to resolve the program interruption. Ah, good catch. I should have caught that one since I got burned by the same nit many months ago. Also, speaking of the system trace (in my earlier post), there is a treasure trove of educational data in there on z/OS behavior and not just on 0C4s and PIC 4s. Study it some time.
