Generations and versions are two different aspects of a GDG.
Generations is which everyone is aware of and its max limit
is 255.
For creating a new generation if we specify gdg base(+1)
then a new generaion would be created and we would be
specifying the dcb parameters for the new generation.
As per my knowledge generally all the gdg versions have the
same dcb parameters but when they change then we go for
specifying a version which means there is a difference in
the attributes of the gdg.
a version is used to continue the same gdg base with a
different set of attributes and it would be specified as
gdg base.v00 and the next would be gdg base.v01.

Answer / necron
Can you be a bit more specific, i did not get your question.
are you talking about the number of gdg versions to be
maintained? they can be set by the LIMIT parameter in the
GDG declaration.

Answer / guest
Hi,
The question speaks more about VERSION of GDG.
As of now the version will be always zero only.
If you want a versino in you GDG you need to specify,
dd DSN=A.B.D(0001)V01 and other parameters.
or rename the Generation.
