Likely true. However, remember that a PDSE cannot be shared except within a single SYSPLEX. If you try to share it across multiple SYSPLEXes or MONOPLEXes, then "results are undefined" and likely to be terrible (corrupted PDSEs). > > The Dynamic BLDL function causes me a little concern.

It can be used to buffer any load library, not just the LINKLIST. ./ ADD NAME=CSVLLAnn LIBRARIES(-LNKLST-, NPHPN.PGM.LOADLIB, DCHPN.ENDEVOR.EZTPLUS.LOADLIB) FREEZE(-LNKLST-, NPHPN.PGM.LOADLIB, DCHPN.ENDEVOR.EZTPLUS.LOADLIB) ./ENDUP is an example. > > The remote Data Compare is used in batch to compare PDS¹s on the QA & > Production systems.
