I fully support Phil's claim! I have been sharing minidisks between several systems for years and any change is hard work, though error-prone, to keep those 100% synchronous without ESM and *MAP* programs working across system boundaries.

Donna Walker (whom some of you will remember) once had a system that would lose a certain user's A-disk periodically. Nothing appeared in EREP. Finally turned out an FBA DASD overlapped page space by 1 page. So occasionally the system would manage to use that page, irritating the CMS file system... Gee, do you suppose this is why we have DISKMAP and MAPDISK and DIRMAP and friends? Now we need cross-system versions! ...phsiii
