A generation data set (or
generation)
is a version of a
z/OS data set that is stored as a member of a generation
data group. These generations are supported by
z/OS; they differ from
the generation data sets supported by SAS. For detailed information
about
z/OS generations, see your IBM documentation. For information
about SAS generation data sets, see the
SAS Language Reference: Concepts. For
more information, see
Allocating a Multivolume Generation Data Group.
Both standard external
files and SAS libraries can be stored and managed as generation data
groups. The following sections describe the various methods of allocating
new and existing generations.
