Q 3 - How much time Step2 will have for execution, if Step1 will take 2.5 minutes?

//TXXXXXX JOB (XXXXX), ’XXXX’, TIME = 4
//STEP1 EXEC PGM = PR1, TIME = 4
//STEP2 EXEC PGM = PR2, TIME = 0

Answer : C

Explanation

The job TIME limit takes precedence over the step time limit. Step2 will have 1.5 minutes for execution. If it goes beyond that, this job will abend.

Q 4 - What will happen to Step2 if Step1 executes with RC=0?

//TXXXXXX JOB (XXXXX), ’XXXX’
//STEP1 EXEC PGM = PR1
//STEP2 EXEC PGM = PR2, COND = EVEN

A - Step2 will be bypassed

B - Step2 will be executed

C - None of these

Answer : B

Explanation

Step2 will be executed as we have coded EVEN which means this step will be executed even if all other steps abends or not. If you will code EVEN then step will be executed irrespective of results from other steps.

Q 5 - Which step will be executed after Step1, if Step1 executes with RC=4?

//TXXXXXX JOB (XXXXX), ’XXXX’
//STEP1 EXEC PGM = PR1
// IF STEP1.RC GT 0 THEN                      
//STEP2 EXEC PGM = PR2
// ELSE
//STEP3 EXEC PGM = PR3
// END-IF

A - Step2 will be executed

B - Step3 will be executed

C - None of these

Answer : A

Explanation

If condition is 4 Greater than 0 and this condition is true, so Step2 will be executed and Step3 will be bypassed.
