John, How about DISP=OVR (i.e., overwrite) ? If the dataset exists, then have the initiator perform a delete / hdelete operation. Thereafter, change the disposition to DISP=NEW.

I just had another wacky thought of a new one that I would like. I can't really think of a good, three character, value for it. But what it would do is what UNIX does with a PATHOPTS=(OTRUNC,OCREAT). It would, like MOD, either reuse an existing allocation, or create a new one. But, unlike MOD, it would not add to the end, but put an EOF at the beginning of the dataset and start writing over the old data. What do others think?
