JCL Condition​

Below is the sample JCL to execute the a step to generate the different condition based on input. Use this sample JCL step to create a multi step JCL to trigger/skip the steps based on conditions.

note

Replace <Your ID> with your training id and <YOUR REXX EXEC> with your previously create REXX EXEC dataset which have RETRC member.

//<YOUR ID>E  JOB ,TYPRUN=HOLD,NOTIFY=&SYSUID                             
//COMBINE   EXEC PGM=IRXJCL,PARM='RETRC 2'             
//SYSEXEC   DD DSN=<YOUR REXX EXEC>,DISP=SHR       
//SYSTSIN   DD DUMMY
//SYSTSPRT  DD SYSOUT=*

Pre requiste before you can execute below JCL's​

Create a dataset with RECFM=FB,LRECL=80,BLKSIZE to store the below REXX with name RETRC.

/* REXX RETURN EXPECTED RC */
PARSE ARG RETCD
SAY RETCD
IF DATATYPE(RETCD) <> 'NUM' THEN RETCD = 0
EXIT RETCD

Scenario 1​

Create a Job with 5 Steps each with Following Specification

  • STEP1
    • If Runs it should Return with RC = 8
  • STEP2
    • If Runs it should Return with RC = 6
    • It should Run only if STEP1 RC = 6
  • STEP3
    • If Runs it should Return with RC = 4
    • It should Run only if STEP2 RC = 8
  • STEP4
    • If Runs it should Return with RC = 2
    • It should Run only If STEP1 RC = 8
  • STEP5
    • If Runs it should Return with RC = 16
    • It Should Run only If STEP4 RC is Between 4 to 8
