What's a "TSO user"?
Often the mode of enforcement selected by an authority serves to
clarify an elliptical definition. IBM provided some enforcement
of the limit. It seems it would have been easy enough to impose
a limit of 8 concurrent tasks (or 8 concurrent address spaces)
running the TSO TMP. IBM chose instead to enforce a limit of 8
concurrent uses of a particular interface to the TMP. By choosing
that point of enforcement, IBM implicitly provided the missing
definition.
When I posted my earlier contribution to this thread I was tempted
to add that if products that bypass the limit become prevalent,
IBM will likely redesign its enforcement. That option remains
available to IBM.
Contrariwise, IBM has provided a new interface to the TMP, in the
poorly understood "address TSO" subcommand environment of Rexx
EXECs run under z/OS Unix shells. With very simple descriptor
plumbing, this can be escalated into a fairly interactive session.
Would this violate the limit as you appear to see it? (My
experiments did not strain the parameter: our site is licensed
for full z/OS.)
For an alternative that should be completely acceptable to Peter,
try the following (I'm very close to this in my own operations):
Keep your JCL in HFS or NFS. Use vi, emacs, nedit, or any
workstation editor to maintain it. Submit jobs with FTP or
via internal reader:
