Example 8

The following example shows an IF/THEN/ELSE/ENDIF statement construct with a deferred step restart.

//DEFER2 JOB RESTART=(STEP3)
//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:

The conditions on statement IF1 will be checked before executing STEP3.
STEP1.RC=0 tests false because STEP1 did not execute and cannot be correctly evaluated.
¬STEP1.RUN tests true; therefore, STEP3 and STEP4 will execute and STEP5, STEP6, and STEP7 will not execute.

Note: Without the ¬STEP1.RUN condition, STEP3 and STEP4 would not run, and STEP5, STEP6, and STEP7 would run.
