Can I specify dummy VSAM dataset with AMP = 'AMORG' in a JCL?

  1. True

  2. False


Correct Option: A

DEFINE PATH command creates an alias for

  1. Bldindex

  2. non-VSAM datasets

  3. VSAM base cluster

  4. Define path


Correct Option: C
  1. Bldindex

  2. non-VSAM datasets

  3. VSAM base cluster

  4. Define path


Correct Option: B

How should be VSAM file defined in order that it can be accessed both in CICS and in BATCH environment?

  1. SHAREOPTION (1,3)

  2. SHAREOPTION (2,3)

  3. SHAREOPTION (3,1)

  4. SHAREOPTION (3,2)


Correct Option: B
  1. Through the USER parameter

  2. Through the USER and PASSWORD parameter

  3. Through the RACF parameter

  4. By notifying the console operation to override authority


Correct Option: B

Many JCL statements contain specific values designed to direct and control the execution of the statement. What are these fields called?

  1. Linkage variables

  2. Parameters

  3. Control libraries

  4. Includes


Correct Option: B

AI Explanation

To answer this question, you need to understand the purpose of these values in JCL statements. Let's go through each option to understand why it is correct or incorrect:

Option A) Linkage variables - This option is incorrect because linkage variables are used in programming languages like COBOL to pass data between programs, not in JCL statements.

Option B) Parameters - This option is correct because JCL statements often contain specific values, known as parameters, that are used to direct and control the execution of the statement. These parameters can specify things like program names, dataset names, and other instructions for the system.

Option C) Control libraries - This option is incorrect because control libraries refer to datasets that contain control statements or programs used by the system during job execution, rather than specific values in JCL statements.

Option D) Includes - This option is incorrect because includes are used in programming languages like COBOL to include external code or copybooks, not in JCL statements.

The correct answer is B) Parameters. This option is correct because JCL statements often contain specific values, known as parameters, that are used to direct and control the execution of the statement.

Can an individual step be restricted from using all the job's allowed CPU time?

  1. Yes

  2. No

  3. Only in catalogued procedures

  4. Through the STEPTIME parameter


Correct Option: A

AI Explanation

To answer this question, you need to understand how job execution and CPU time restrictions work.

Option A) Yes - This option is correct. An individual step can be restricted from using all the job's allowed CPU time. In mainframe environments, it is possible to set CPU time limits for individual steps within a job. This can be done using the TIME parameter in the JCL (Job Control Language) or by using system commands during job execution.

Option B) No - This option is incorrect. An individual step can indeed be restricted from using all the job's allowed CPU time.

Option C) Only in catalogued procedures - This option is incorrect. The ability to restrict CPU time is not limited to catalogued procedures. It can be applied to any individual step within a job.

Option D) Through the STEPTIME parameter - This option is incorrect. Although the STEPTIME parameter can be used to specify the maximum time that a step is allowed to run, it does not directly restrict the CPU time usage of the step.

The correct answer is A) Yes. An individual step can be restricted from using all the job's allowed CPU time by setting CPU time limits for that particular step.

What is the maximum length of a single line of JCL?

  1. 72

  2. 74

  3. 73

  4. 71


Correct Option: D

AI Explanation

To answer this question, you need to be familiar with the Job Control Language (JCL) used in mainframe systems.

The correct answer is D) 71.

JCL is a scripting language used to control batch processing on IBM mainframe systems. In JCL, each statement or command should be written on a separate line. The maximum length of a single line in JCL is 71 characters.

The correct answer is option D) 71. This option is correct because it represents the maximum length of a single line in JCL.

What is the purpose of DD DUMMY statement?

  1. Marks a deleted DD statement

  2. Begins an interpreted command stream

  3. Specifies no space allocation & no disposition processing

  4. Suppress command processing


Correct Option: D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Marks a deleted DD statement - This option is incorrect. The purpose of the DD DUMMY statement is not to mark a deleted DD statement.

Option B) Begins an interpreted command stream - This option is incorrect. The DD DUMMY statement does not begin an interpreted command stream.

Option C) Specifies no space allocation & no disposition processing - This option is incorrect. While the DD DUMMY statement does not allocate space, it does not specify no disposition processing.

Option D) Suppress command processing - This option is correct. The purpose of the DD DUMMY statement is to suppress command processing. It is typically used in JCL (Job Control Language) to define a dummy data set that does not contain any actual data, but is required to satisfy the syntax of the JCL.

The correct answer is D) Suppress command processing. This option is correct because the DD DUMMY statement is used to suppress command processing.

I am using internal sort in my cobol program . Is there any way to test the return code of operation???

  1. No , we can't check the return code for internal sort however for external sort it can be done

  2. YES,by using SORT-RETURN special register

  3. YES, we can test via Run jcl.

  4. YES,by checking in listing of the proram


Correct Option: B

What will happen if I change the below code MOVE ZERO TO TOTAL . PERFORM VARYING I FROM 1 BY 1 UNTIL I > 100 COMPUTE TOTAL = TOTAL + ITEM(i) * DISCOUNT END-PERFORM to the follwing code MOVE ZERO TO TOTAL PERFORM VARYING I FROM 1 BY 1 UNTIL I > 100 COMPUTE TOTAL = TOTAL + ITEM(i) END-PERFORM COMPUTE TOTAL = TOTAL * DISCOUNT

  2. syntax error will occur

  3. Run time error

  4. NO ERROR with same result
