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.
