Used to indicate the step, procedure step or checkpoint at which the system is to restart the job.

Syntax: RESTART=STEPNAME

If the step we, which we want to restart is in a procedure then we have to mention the procedure name also before the stepname in the restart instruction.

Syntax: RESTART=PROCEDURE-NAME.STEPNAME

RD=R (Restart, Checkpoint allowed)à  is to restart AUTOMATICALLY from the previous check point if the job
abended  .  

RD=RNC (Restart, No Checkpoints allowed) à  job suppresses from executing  AUTOMATICALLY. The operator had to do it.

RESTART = * à Restart the job from the beginning.

RESTART = Stepname à Restart from specified STEP to end of the job.

RESTART = procStepName.Stepname à Restart from the specified PROC step.

If u wanted to execute only one particular step. Remove ‘*’ from ‘//*’ after the Step and submit the job:

//jobname JOB ……RESTART = Step2

//Step1  EXEC PGM=pgm1

//Step2  EXEC PGM=pgm2

…

//         

//Step3 EXEC PGM=pgm3

//Step4 EXEC PGM=pgm4

If u remove the ‘*’ from ‘//*’, the execution will stop at that point of the JCL. So in the above example only STEP2 will be executed.

Few Overrides:

RD, COND and REGION on JOB statement will override RD, COND and REGION on STEP statement.
