Anish Mahajan, what would be the MOST helpful would be for you to read the SDSF manual and find out what batch utilities are available. Sitting back and waiting to be spoon-fed is NOT considered a positive attitude on this forum -- YOU are expected to put forth some effort, just like all the members who reply did when they were learning these concepts. You've already got one big strike against you for repeatedly using shortcut abbreviations on a forum that supports use of proper English with full sentences. If you cannot even look up anything in a manual, that is a second big strike against you. With ten months experience in mainframes, you should be able to (at a minimum) find the SDSF manual relating to batch at your site (if you cannot, ask a coworker, your team leader, or site support staff), read it, and learn for yourself. If you cannot accomplish these minimal goals, why would we expect that giving you more difficult tasks (such as understanding JCL statements) would even be worth doing?
