- partitioned data set — (file format) (PDS) A data set on an IBM mainframe that contains members, each of which acts like a separate data set.

The syntax for a member is NAME.OF.PDS(MEMBER) although some systems (such as Phoenix) could use NAME.OF.PDS:MEMBER Original PDSes were of fixed size, and needed frequent compression to recover space after deleting or changing members. Newer PDS/E Extended PDSes do not have this problem.

The first 8 bytes of data are transferred in 3 CPU cycles, and the next 3 8-byte pieces of data are transferred in one cycle each.
