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.
