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

A,D Correct answer
Explanation

Step 1 can use 6 seconds of CPU time as specified by TIME=(,6) (A is true). Each step is limited to its specific time, but the entire job is limited to 10 seconds from the JOB statement (D is true). Statement B is false - Step 2 inherits the 10-second limit from the JOB statement. Statement C is false - Step 3's 15-second specification is overridden by the JOB's 10-second limit.
