Answer / varun v

It will create a GDG generation which is one ahead of the
current generation.

Example:
Suppose the current generation is ***.G0001V00
and now instead of creating (+1), you have given (+2) in
your JCL and submitted the job. Now the new generation
created will be ***.G0003V00

Similarly if you give (+4) in the JCL, the new generation
created will be ***.G0005V00

Answer / jaanu

Nothing will happen
it just giving the +2 of the previous generation version no.
Thats it
ex:1st> GDG.G0004V00
next>GDG.G0006V00
