Agreed. >I've thought of having z/OS provide some customer-specifiable option that >would require DISP=OLD in order to compress a PDS to protect. Is that of >interest? It would default to current behavior (i.e., not require) Good idea. IEBCOPY could check the COPY statements, then the DISP field and also the option before working on it. But, will your idea work if you specify for IEBCOPY this: COPY OUTDD=B,INDD=(A,B,C,B) Dataset B will be compressed after A is copied to B and again after C was copied also to B?
