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.

What is GDG and what is the maximum limit of versions that can be created?
Hi, I have a requirement File A : I have 6 records out of which 4 are same. File B: I have 8 records out of 6 records are same. The 4 records in FILEA and 6 records in FILE B are same. If we substract we will get two records, I need these two records in output file This is because to remove the duplicates from the database. Through easytrieve we can compare but for that there should not duplicates, but in my file I have duplicates. Thanks in advance!!
