How can the disposition of sysout datasets be set for an entire jobstream

  1. SYSOUT parameter

  2. OUTPUT parameter

  3. DEFAULT parameter

  4. DEST keyword


Correct Option: A

AI Explanation

To answer this question, you need to understand how the disposition of SYSOUT datasets can be set for an entire jobstream.

Option A) SYSOUT parameter - This option is correct because you can use the SYSOUT parameter to specify the disposition of the SYSOUT datasets for an entire jobstream. By providing a specific disposition value (e.g., KEEP, DELETE), you can control what happens to the output datasets after the job completes.

Option B) OUTPUT parameter - This option is incorrect because the OUTPUT parameter is used to specify the destination and characteristics of the output from individual job steps, not for setting the disposition of SYSOUT datasets for the entire jobstream.

Option C) DEFAULT parameter - This option is incorrect because there is no specific parameter called DEFAULT that is used to set the disposition of SYSOUT datasets for the entire jobstream.

Option D) DEST keyword - This option is incorrect because the DEST keyword is used within the OUTPUT parameter to specify the destination for the output from individual job steps, not for setting the disposition of SYSOUT datasets for the entire jobstream.

The correct answer is Option A) SYSOUT parameter. This option is correct because you can use the SYSOUT parameter to set the disposition of SYSOUT datasets for an entire jobstream.

What is the function of DD name parameter with a 2 part structure; Audit.Report

  1. Override the Audit DD statement in the report

  2. Override the Report DD statement in the Audit procedure

  3. Concatenate a dataset onto a DD statement in a called module

  4. Delete the Audit DD statement in the Report


Correct Option: B

AI Explanation

To answer this question, we need to understand the purpose of the DD name parameter with a two-part structure.

The DD name parameter is used in JCL (Job Control Language) to define a logical name for a dataset or file that is referenced in a program or procedure. The DD name parameter is typically followed by a dataset name or file name.

In the given scenario, the DD name parameter is "Audit.Report" which has a two-part structure. The first part "Audit" represents the DD name for a dataset or file, and the second part "Report" represents the DD name used in the Audit procedure.

The correct answer is B) Override the Report DD statement in the Audit procedure.

Explanation for Option B) Override the Report DD statement in the Audit procedure: When the DD name parameter "Audit.Report" is used in the Audit procedure, it overrides the DD statement for the dataset or file named "Report" that is referenced in the Audit procedure. This means that the Audit procedure will use a different dataset or file instead of the one specified in the original Report DD statement.

What is the function of the STEPLIB DD statement?

  1. Identify a library to be searched for programs named in the EXEC statement

  2. Identify a library containing executable job steps

  3. Override the system step library within a job stream

  4. All of the above


Correct Option: D

AI Explanation

To answer this question, you need to understand the purpose of the STEPLIB DD statement in JCL (Job Control Language).

Option A) Identify a library to be searched for programs named in the EXEC statement - This option is correct. The STEPLIB DD statement is used to specify a library or libraries that are to be searched for programs named in the EXEC statement. This allows the system to locate and execute the required program.

Option B) Identify a library containing executable job steps - This option is incorrect. The STEPLIB DD statement is not used to identify a library containing executable job steps. It is used specifically for programs named in the EXEC statement.

Option C) Override the system step library within a job stream - This option is incorrect. The STEPLIB DD statement does not override the system step library within a job stream. It is used to specify additional libraries to be searched for programs.

Option D) All of the above - This option is correct. The STEPLIB DD statement serves all the mentioned functions. It identifies a library to be searched for programs named in the EXEC statement, specifies additional libraries containing executable programs, and can override the system step library within a job stream.

The correct answer is D) All of the above. This option is correct because the STEPLIB DD statement can perform all the mentioned functions.

A DD statement consists of 4 fields. Name them :-

  1. Name, DD, Space, Device

  2. Format, Name, DD, Space

  3. DD, parameter, device, format

  4. Name, DD, parameter, comments


Correct Option: D
  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: C
