This type of dataset is regularly used to keep executable programs (load modules), supply application libraries (mainly Assembler macro definitions). A PDS is most incredibly analogous to a Zip record on microcomputers, besides the documents stored in a PDS aren't compressed.
The Partitioned Data Set can only allocate on a unmarried extent with the maximum size of 65536 tracks.
Besides participants, a PDS is composed also of their listing.
Each member may be accessed directly using the directory structure. Once a member is positioned, the statistics saved in that member is dealt with in the equal way as a PS (sequential) records set.
