Multiple choice technology mainframe

Consider the following: //TU00001T JOB ATUT000,TU00001,CLASS=7,MSGCLASS=X,TIME=(,10) //STEP1 EXEC PGM=PROGRAM1,TIME=(,6) //STEP2 EXEC PGM=PROGRAM2 //STEP3 EXEC PGM=PROGRAM3,TIME=(,15) Which of the following statements are true?

  1. Step 1 can use 6 seconds of CPU time.

  2. Step 2 has no time limitations.

  3. Step 3 can use 15 seconds of CPU time.

  4. Each step is limited to its specifically mentioned time, but the entire job can only use 10
Reveal answer Fill a bubble to check yourself
A,D Correct answer
Explanation

This JOB specifies TIME=(,10) meaning 10 seconds total for the entire job. STEP1 has TIME=(,6) giving it 6 seconds. STEP2 has no TIME parameter, so it uses the JOB's 10-second limit. STEP3 has TIME=(,15) but is constrained by the JOB's 10-second total. Option A is correct because STEP1's TIME parameter allows 6 seconds. Option D is correct because each step can use its specified time, but the JOB's 10-second limit applies to the total. Option B is incorrect - STEP2 is limited by the JOB's 10 seconds. Option C is incorrect - STEP3 cannot use 15 seconds because the JOB only allows 10 total.
