Q 1 - In Job processing, what happens in Conversion stage?

A - Selection of Initiator for execution of Job

B - Job statement is converted into an interpreted text to be understood by JES and stored into a dataset, which we call as SPOOL

C - Job is taken as an input to JES

D - Allocated resources and the JES SPOOL space is released

Answer : B

Explanation

The JCL along with the PROC is converted into an interpreted text to be understood by JES and stored into a dataset, which we call as SPOOL.

Q 2 - In Job processing, what happens in Execution stage?

A - Selection of Initiator for execution of Job

B - Job statement is converted into an interpreted text to be understood by JES and stored into a dataset, which we call as SPOOL

C - Job is taken as an input to JES

D - Allocated resources and the JES SPOOL space is released

Answer : A

Explanation

When the job reaches its highest priority, it is taken up for execution from the job queue. The JCL is read from the SPOOL, the program is executed and the output is redirected to the corresponding output destination as specified in the JCL.

Q 3 - What will happen to Step2 if Step1 executes with RC=0?

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

A - Step2 will be bypassed

B - Step2 will be executed

C - None of these

Answer : B

Explanation

It will read the condition on step2 as 4 Less than 0, which is false, so step will be executed. If condition is true then only the step will be bypassed.

Q 4 - A STEPLIB statement is used in order to identify the location of the program to be executed within a Job Step. The STEPLIB statement is specified after the EXEC statement and before the DD statement of the job step. State whether true or false?

A - True

B - False

Answer : A

Explanation

This statement is correct.

Q 5 - What is use of DISP parameter in DD statement?

A - Space required for the dataset

B - Physical characteristics of a dataset

C - Disposition of dataset

D - Physical Dataset Name

Answer : C

Explanation

The DISP parameter is used to describe the status of the dataset, disposition at the end of the job step on normal and abnormal completion. DISP is not required in a DD statement only when the dataset gets created and deleted in the same job step (like the temporary datasets). Syntax : DISP=(status, normal-disposition, abnormal-disposition)

Q 6 - How the file will be sorted if you will use the following sort card?

//STEP1 	 EXEC PGM = SORT
//SYSPRINT	 DD SYSOUT = *
//SYSOUT	 DD SYSOUT = *
//SORTIN	 DD DSN = input.data.set,DISP=SHR
//SORTOUT	 DD	DSN=output.data.set
//SYSIN 	 DD  *
 SORT FIELDS = (1,06,CH,D)
/*

A - SORT FIELDS = (1,06,CH,D) instructs the utility to sort the file based on the CHARACTER field that starts from POSITION 1 and of LENGTH 6 in DESENDING order

B - SORT FIELDS = (1,06,CH,D) instructs the utility to sort the file based on the CHARACTER field that starts from POSITION 6 and of LENGTH 1 in ASCENDING order

C - SORT FIELDS = (1,06,CH,D) instructs the utility to sort the file based on the CHARACTER field that starts from POSITION 6 and of LENGTH 1 in DESENDING order

D - SORT FIELDS = (1,06,CH,D) instructs the utility to sort the file based on the CHARACTER field that starts from POSITION 1 and of LENGTH 6 in ASCENDING order

Answer : A

Explanation

This is self explanatory.

Q 7 - A job is a unit of work which can be made up of many job steps. Each job step is specified in a Job Control Language (JCL) through a set of Job Control Statements. State whether true or false?

A - False

B - True
