What is Automatic Restart ? EXEC PGM = PROG1, RD = R (Is it the Restart of a JOBSTEP or Restarting the execution of the program?) Do we Restart it or it automatically Restarts executing again and again ? Then when it will finish executing ? or After Abending, when we submit it again, then it is Restarted from the Last successful Checkpoint ? If some JOBSTEP is abending, what is the benifit to Restart it, WILL IT NOT ABEND AGAIN if you don't change the LOGIC ?
