Hi Steff,
Please look at JES2 Exit 4 (There is a sample in CBT File 122) and (SMF
Exit) IEFUJV (There is a sample in CBT File 573).
Regards,
David

What is the best way of modifying JCL after the job has been
submitted, in order to conditionally add another DDNAME to a JOB STEP? Or
perhaps adding parameters to the PARM string on the EXEC statement.
We were thinking of using the IEFUSI exit point, allocating a file
dynamically before the main program of the job-step is attached. I gather
there are also JES2 exits (are they simple exits or the more flexible exit
points?) that are appropriate to the task and would be interested to hear
advice from other system programmers.
Two other questions: are these exits specified in the PARMLIB or via some
other mechanism? And what happens if the exit fails in some way? What
action does the system take?
Thanks in advance,
Steff Gladstone
