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 ?

COND -> step1 . . step2, Step2, Executes if the CC of step1 is 0. But even if it is NOT 0 and if we dont give COND, will step2 be executed ?

IF WE GIVE COND on step3 then, What does the following mean ? And Just adding to that, All the below COND are VALID as per the specifications. (i) COND = (8,LT,step1,step2) ---(AND/OR ?) (ii) COND = (8,LT,step1,step2, ONLY), (iii) COND = (8,LT,step1,ONLY) will it execute only if this condition is true or only if step1 ABENDS ? (iv) COND = (8,LT,step1,step2,EVEN), (v) COND = (8,LT,step1,EVEN) ?
