I was not going to bring this up, but since you did, yes MVS
allows, for example, DSN='JAN 2016 WK 4 PAYROLL' (limit is 44
chars) for either DISK or TAPE because, originally, sharing of
volumes between DOS|DOS/VS|DOS/VSE and I think VSE-ESA. Doing
Connect:Direct I had to point this out as a possibility, and
while doing DOS to MVS migrations we had to have some discussions
with clients about MVS data set naming rules and what SMS requires.

I got curious about how many possible different values could exist in a
dataset "node". A node can be 1 to 8 characters long. The first character
must be A-Z @#$ or 29 characters. Subsequent characters are those 29 plus
digits 0-9 and a dash (the dash was a surprise to me).
I think that set of restrictions is for _cataloged_ data sets. For
_uncataloged_ data sets, there are no restrictions about the content of a data
set qualifier except (possibly?) for the length.
