A
data
set is a collection of logically related data and can be a source
program, a library of macros, or a file of data records used by a
processing program. Data records are the basic unit of information
used by a processing program. By placing your data into volumes of
organized data sets, you can save and process the data. You can also
print the contents of a data set or display the contents on a terminal.
Exception: z/OS UNIX files are different from
the typical data set because they are byte oriented rather than record
oriented.
