Answer / balu

gdg data set(0) we can know which data set gdg is using

Answer / stu

The question is confusing. A GDG (Generation Data Group)
consists of a base (no data, but defines the name, how many
generations of data files will be kept, etc.), and the
generations of data files.

The data files will all have the same file name except for
the last name node. Here are 3 generations of a GDG with
their actual file names.

xxx.xxxxx.xxxx.G000V01 alias=xxx.xxxxx.xxxx(-2)
xxx.xxxxx.xxxx.G000V02 alias=xxx.xxxxx.xxxx(-1)
xxx.xxxxx.xxxx.G000V03 alias=xxx.xxxxx.xxxx(0)

If another generation is created, G000V00, it becomes (0),
G000V03 becomes (-1), and so forth.

If the jcl cites xxx.xxxxx.xxxx by itself, it concatenates
all the existing generations in earliest to latest order.
