In a Job , there are 3 steps in order . They are STEP1 , STEP2 and STEP3 .
Is it possible to execute STEP2 , STEP1 , STEP3 without changing the order of steps in the JCL ? i.e. firstly step2 should run , then step1 and step3 should run.

You're welcome.

Keep in mind, JCL, when started was developed with the very feel of executing "daily routine tasks" which can run without or very minimal human intervention. They were the taks, which should be performed in some order, one after other - so asking if we can run the steps in different manner than they are coded, actually does not make much sense with the very idea of JCL evolution.
