To the last question, if it required the applications to be rewritten: Yes. My intention was not to solve my immediate need, but to propose a more general solution that can be used by wider group. Regarding zFS: this would require a change in many places: procedures, JCLs and routines for administration of space (for the UNIX side). Of course, if You see UNIX as the future and MVS (or maybe just its file system) as something to leave behind, You are right. But my view is that MVS could and should be improved.
