Hi Allan, Why is JES2 Exit 6 better than Exit 4 for this purpose?

Classification: Confidential IEFUSI is too late in the process. I suggest JES2 EXIT6 (or EXIT26?) depending on the JES2 Environment. In both cases, you must be prepared to manipulate the INTERPRETER internal text (very similar in concept to dynamic allocation).

Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] 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?
