Which type of data sets contain members?
A partitioned data set (PDS) is a collection of sequential data sets, called members.
- Consists of a directory and one or more members.
- Also called a library.
What is a sequential data set?
In a sequential data set, records are data items that are stored consecutively. A partitioned data set consists of a directory and members. The directory holds the address of each member and thus makes it possible to access each member directly. Each member consists of sequentially stored records.

What is PDS in JCL?
PDS stands for partitioned data set. Each member within the PDS can be read as a sequential file if you set up your JCL to reference the specific member.
What is directory blocks in PDS?
The directory consists of member entries arranged in ascending order according to the binary value of the member name or alias. PDS member entries vary in length and are blocked into 256-byte blocks. Each block contains as many complete entries as will fit in a maximum of 254 bytes.
How do I search for a member in multiple PDS?
ISPF – Search for a Member in Multiple PDS. I’m sure everyone has come across the need of locating a PDS member, but not remembering exactly on which data set the member is. Well, there is a very simple way of doing this using ISPF option 3.4: In the Command Line enter M member_name (ex: let’s suppose the member you want to locate is TESTMEM.
