Required Parameters

GENERATIONDATAGROUP

Specifies that a generation data group (GDG) entry is to be defined. A GDG can contain both SMS- and non-SMS-managed generation data sets. A generation data set (GDS) cannot be a VSAM data set. If you create a GDG and its catalog is on an SMS-managed volume, you should remove any dependencies on pattern DSCBs. See z/OS DFSMS Using Data Sets for information about GDGs and GDSs.
