Examples of the RD parameter

//STEP1  EXEC PGM=GIIM,RD=R

RD=R specifies that the operator can perform automatic step restart if the job step fails.

//NEST  EXEC PGM=T18,RD=RNC

RD=RNC specifies that, if the step fails, the operator can perform automatic step restart. RD=RNC suppresses automatic and deferred checkpoint restarts.

//CARD  EXEC PGM=WTE,RD=NR

RD=NR specifies that the operator cannot perform automatic step restart or automatic checkpoint restart. However, a CHKPT macro instruction can establish checkpoints to be used later for a deferred restart.

//STP4  EXEC PROC=BILLING,RD.PAID=NC,RD.BILL=NR

This statement calls a cataloged or in-stream procedure BILLING. The statement specifies different restart requests for each of the procedure steps: PAID and BILL.
