How to create a list of all GDG Base names?

Environment

Release:
Component: DISKOS

Resolution

1) Using Vantage 
If Vantage is an option, creating a list of all GDG Base names is an easy task.
Create a user view on the "GDG Data Sets object (OBJ02016)" and select the GDG Bases by specifying filter "ETypeC = B" (B for Base). 
In addition, you can use an "Input List" to limit the list to certain data set hlq's. 


2) Without Vantage
If Vantage is not an option, you can use the IDCAMS command LISTCAT GENERATIONDATAGROUP to list all GDG Base names.
By adding LEVEL(hlq) you can limit that list to a certain hlq.

Here the sample JCL to create a data set with the GDG Base names used in commands as input for another utility:
