tattva,

You can do this in 2 steps.
1. IDCAMS Step - use LISTCAT entries on the GDG base and get the number of active generations.
2. Pass the output of IDCAMS (step 1) to your program which writes to the gdg file and based on the number of active generations you can decide whether to write data to it or not.

This will anyway create a first version but it will not be deleted, instead the contents will be empty. So that next time when the job runs, it will not have any trouble creating the second version.

Will this solve your problem ?

Thanks,
Phantom
