The MASTERJCL residing in PARMLIB can be read via browse or edit (and thus
changed) in TSO ISPF. The likelihood of it being changed would be rare. Can't
imagine any other way to see what it is beside the way you mentioned or my way.
Of course you can see via ISPF who changed it and when.

Yes, it's in the Master address space. There is no guaranty that MSTJCLxx
hasn't changed since IPL, and I know of no operator or TSO command to display
it. The best I can come up with is to use IPCS to view the TIOT and JFCB, or to
run the DSAB chain.

Subject: Re: Where UADS dataset name goes in case of ACF2?
If ACF2 doesn't start UADS usage becomes the norm for logging into TSO. The
MVS or Z/OS, has a definition to allocate UADS. Trying to recall where the
allocation for it is sine it has been a while, but I believe it is in the
Master JCL which in z/OS it is in Parmlib. From there it finds it in the
Master Catalog.
In the case of ACF2 failing a valid set of JCL and a USERID should be present.

Itschak, Your post piqued my interest, but it’s around 35 years since I was
actually involved in RACF, ACF2, TSS and some other non-starters.
I can’t really help further. Sorry!
