I have a job, which is using 6 temporary files. The DISP of the temporary files are DISP=(OLD,PASS) at the last step. I know that the temporary files will be deleted when the JOB completes.
But, I want to know the impact of keeping the temporary dataset's DISP=(OLD,PASS) and DISP=(OLD,DELETE).
Will it use more space on DASD? Or which kind of impact it will cause?
Why should we use DISP=(OLD,DELETE) at the end?
