"MVS"? While MVS is a component of z/OS, the other one is UNIX System Services. As far as I can
tell, USS (no, let's not argue over that short form) is not MVS, it's USS. Yes, they're well-integrated and
talk to each other and all that, but why say "MVS UNIX files"? Why not just "UNIX files"?
Happy to be corrected about the delineation, but that's what I believe I've
observed.
In recent years, we have been trying to go with "z/OS MVS" and "z/OS
UNIX" in our documentation. For data sets or files, if there is any
chance for MVS/UNIX confusion, we say "z/OS MVS data sets" or "z/OS UNIX
files". If there is no possibility for MVS/UNIX confusion, then we just
refer to "data sets" or "files". Any time Gil succeeds in getting a z/OS
MVS facility to work with z/OS UNIX files, we'll have to update our doc! ;)
These terms do leave us exposed to IBM deciding to name some future
version of its flagship mainframe operating system to something other
than z/OS, but they do make it pretty clear which part of the OS is
being discussed at any time.
In the field, we find that despite IBM's attempts to sweep "USS" as an
acronym for "UNIX System Services" under the rug, it refuses to go away
and remains in common use.
