I have a situation where I need to execute a single JCL procedure, but ONLY
execute some steps (including the DSN allocations) for part B or part C,
depending on the return code of part A.
May I suggest you use dynamic allocation for that? I don't think there is any
other way of achieving your requirement.

I concur. Especially if you will be in a JES3 environment. As
another poster commented, I also think JES3 "SETUP" will have a
problem with the VOL= and UNIT= .
Normally, when I do JCL like this, and it must execute in a JES3
environment, I use an IEFBR14 step to start that names the data
sets (disp=new|mod) that IDCAMS will build in a following step.
This IEFBR14 STEP has COND=ONLY. JES3 accepts that and doesn't
fail the JOB with a JCL error.
Your situation is one that I would have to experiment with, but I
think you will need to run TSO in batch with REXX or CLIST using
ALLOC/FREE. You may even have to invoke IDCAMS (LISTC) to get
info that LISTDSI may not be able to provide.
The requirement that this all be in a single JOB is *the*
headache from where I sit.
