Correct Option: B

For creating a PDS file, we need to define Directory Block as 0.

  1. True

  2. False


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of PDS (Partitioned Data Set) files and the role of the Directory Block.

A PDS file is a dataset in IBM's Mainframe operating system, z/OS. It is used to organize related data records into logical groups called members. Each member within a PDS file has its own name and can contain different types of data.

The Directory Block is a special block within a PDS file that contains information about the members present in the PDS. It acts as an index or directory, pointing to the location of each member within the PDS.

Now, coming to the given statement: "For creating a PDS file, we need to define Directory Block as 0."

This statement is incorrect. The Directory Block is automatically created by the system when a new PDS file is created. It is not something that needs to be defined explicitly as 0. The system assigns the appropriate values to the Directory Block based on the PDS file's structure and the members it contains.

Therefore, the correct answer is:

B) False - This option is correct because the Directory Block is automatically created by the system when a PDS file is created. It does not need to be defined as 0.

  1. A: 8-11, B: 12-72

  2. A: 8-11, B: 12-80

Correct Option: A

Which utility is used for Link Edit a program?

  1. IEKL

  2. IEWL

  3. IEBGENER

  4. IEFBR14


Correct Option: B

Which utility is used to CREATE, DELETE, COPY PS/PDS?

  1. IEWL

  2. DSNHPC

  3. IGYCRCTL

  4. IEFBR14


Correct Option: D

AI Explanation

To answer this question, you need to understand the utilities available in mainframe environments for managing PS (Physical Sequential) and PDS (Partitioned Data Set).

Let's go through each option to understand why it is correct or incorrect:

Option A) IEWL - This option is incorrect because IEWL (Interactive Edit and Link) is a utility used for linking and editing programs, not for creating, deleting, or copying PS/PDS.

Option B) DSNHPC - This option is incorrect because DSNHPC (Data Set High-Level Programming Control) is a utility used for managing DB2 objects, not for creating, deleting, or copying PS/PDS.

Option C) IGYCRCTL - This option is incorrect because IGYCRCTL (COBOL Compiler Control) is a utility used for controlling the compilation of COBOL programs, not for creating, deleting, or copying PS/PDS.

Option D) IEFBR14 - This option is correct because IEFBR14 (Dummy Utility) is a utility used for creating, deleting, or copying PS/PDS. It is commonly used to create a new PS or PDS, delete an existing PS or PDS, or copy a PS or PDS to another location.

The correct answer is D) IEFBR14. This option is correct because IEFBR14 is the utility used to create, delete, or copy PS/PDS.
