Yes, if the file is not in sorted order(assecending or descending) then i need to get jcl error after submitting the jcl. I need a condition if the file is not sorted then it should get jcl error. Thanks.
An "abend" is a "system abend" or a "user abend". Look up the terms and understand what they mean, ask, with an explanation of what you understand to that point, if you are unsure.
A JCL error is something wrong with the JCL, syntactically or in some cases logically, which will usually "flush" the job before it gets an opportunity to run (because it can't) or cancels the job once encountered (like duplicate dataset).
A return-code is a value that can be set by any program (if code is included to do so) and whose value can be tested using the Condition Code processing available in JCL. See the JCL manuals.
The only sensible way to arrange your process is to use the final one, the Return-Code with Condition-Code checking.
