About this task
A
generation data group (GDG) is a group of
related data sets. Each data set within a GDG is called a
generation
data set (GDS) or generation. A
GDG base is a
catalog entry for a GDG, and represents a GDG. Rational Developer
for System z provides GDG support that enables you to display and
manipulate GDGs and GDSs in the Remote Systems view. The z/OS Projects
and Remote z/OS Search views enable you to display and work with GDSs.
All functions available for data sets are available for GDSs, except
the following:
- Add a GDG to a subproject

available for a data set, but you cannot add a GDG as a group to a
subproject.
