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. Partitioned data sets are more
space-efficient than individual data sets, because they can put more than one
data set on a track. They are also used to hold libraries, with one function per
member. 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.
