All, Since I started this "question", so how is "one" to check for the existence of datasets if we can't really trust IEFBR14 ? Yeah, I can write an Assembler routine, by why, when BR14 is supposed to work...I have staging datasets we use to build our product, my first step is the IEFBR14 , to delete these datasets if they exist, if not fine give me a return code I can test for and proceed on with the other steps.
