Use PASS only when you are creating temporary datasets. When creating permanent datasets, you should use CATLG rather than PASS, or your permanent dataset may be deleted. PASS'ed temporary datasets are deleted at "end of job", however, may be deleted earlier in the job if you read the temporary dataset back in a job step with DISP=(OLD,DELETE). If you have to READ a tape dataset into several job steps, you would want to use a VOL=(,RETAIN) parameter to prevent the tape from having to be re-mounted multiple times within the same job.
