Q7. What Is Basic Difference Between "directory" And "pds" In Ibm Mainframe?
A PDS or Partitioned Data Set is a dataset containing multiple members, every of which holds a separate sub-facts set, much like a listing in different styles of document structures. This kind of dataset is often used to hold executable packages (load modules), supply program libraries (specifically Assembler macro definitions). A PDS is maximum really analogous to a Zip file on microcomputers, except the files saved in a PDS are not compressed.
The Partitioned Data Set can only allocate on a single volume with the maximum size of 65536 tracks. Besides members, a PDS is composed also of their listing. Each member can be accessed at once the use of the listing shape. Once a member is positioned, the information saved in that member is treated in the identical manner as a PS (sequential) records set.

This form of dataset is regularly used to preserve executable applications (load modules), supply application libraries (in particular Assembler macro definitions). A PDS is maximum relatively analogous to a Zip file on microcomputers, besides the documents saved in a PDS aren't compressed.
The Partitioned Data Set can only allocate on a unmarried quantity with the most size of 65536 tracks.
Besides participants, a PDS is composed also of their directory.
Each member can be accessed at once the use of the listing structure. Once a member is placed, the information saved in that member is treated inside the identical manner as a PS (sequential) records set.
