Example 7

The following example shows an IF/THEN/ELSE/ENDIF statement construct with a deferred checkpoint restart. 
//DEFER1 JOB RESTART=(STEP2,CHECK004)
//STEP1  EXEC PGM=IEFBR14
//IF1    IF STEP1.RC=0 | ¬STEP1.RUN THEN
//STEP2  EXEC PGM=DEBIT1
//STEP3  EXEC PGM=CREDIT1
//STEP4  EXEC PGM=SUMMARY1
//       ELSE
//STEP5  EXEC PGM=DEBIT2
//STEP6  EXEC PGM=CREDIT2
//STEP7  EXEC PGM=SUMMARY2
//       ENDIF
Processing for the IF/THEN/ELSE/ENDIF construct named IF1 is as follows:
  1. The conditions on statement IF1 will be checked before executing STEP2.
  2. STEP1.RC=0 tests false because STEP1 did not execute and cannot be correctly evaluated.
  3. ¬STEP1.RUN tests true; therefore, STEP2, STEP3, and STEP4 will execute and STEP5, STEP6, and STEP7 will not execute.
Note: Without the ¬STEP.RUN condition, STEP2, STEP3, and STEP4 would not execute and STEP5, STEP6, and STEP7 would execute.
