Would it be feasible to submit the job with TYPRUN=HOLD (TYPRUN=SCAN is

broken) and scan the resolved JESJCL with SDSF, then cancel it?
No SDSF at this shop, yet. We use $AVRS and some other piece of junk which is
a small improvement on ISPF 3.8.
But you might be on the right track. From what I have read, JCL processing
goes thru these stages: Reader, Converter, Interpreter, Resource Allocation,
Job Selection and Scheduling, Output, and Purge. It seems that TYPRUN=SCAN
only does the reader and converter phases. I suspect TYPRUN=HOLD is probably
the same, or maybe it does the Interpreter too. In any event, the converter
phase does the PROC/SET/INCLUDE resolution and stores the result as C/I text on
the JES SPOOL. If only there was a way to pull this out of spool and write to
a regular dataset.
Unlike JES2, JES3 C/I does both conversion and interpretation before execution.
In addition, JES3 provides the JCLTEST and JSTTEST tools for doing even more
in-depth JCL testing. From z/OS JES3 Initialization and Tuning Guide:
"During the prescan phase, the JCL for the job is examined for PGM=JCLTEST
or PGM=JSTTEST. If PGM=JCLTEST is found on an EXEC statement, the JCL is
interpreted and the job is then express canceled on completion of the CI
DSP. If PGM=JSTTEST is found on an EXEC statement, the job is processed
through the prescan and postscan phases, a printed format of the job
summary table (JST) is printed on the JESYSMSG data set, and the job is
then canceled-with-print on completion of the CI DSP. For more information
on JCLTEST and JSTTEST, see z/OS JES3 Diagnosis."
You can write a REXX that submits your jobs, changes the EXEC to PGM=JSTTEST and
then examines the results. The JST table will tell you lots of great information
about data set use.
You can use the TSO/E OUTPUT command to copy the results from SPOOL to a data
set. Also, if you submit the job(s) via FTP, you can get the results back via
FTP. [Better tools are also available... ;-) ]
