check a GDG generation is present in catalog or not?

[Gagan Saini]

Hi every one,

I want to check in the first step of a JOB whether the GDG has generations or not. Could you plz tell me how can I solve this issue?

Schedule the job so that it runs after the dataset is created. Alternatively, use IDCAMS to list the entries and then a program to check through the resultant list and set an appropriate return code.
