What is a generation data group? That is, each data set is historically related to the others in the group. If the attributes and organizations of all generations in a group are identical, the generations can be retrieved together as a single data set. Advantages to grouping related data sets include: All of the data sets in the group can be referred to by a common name. The operating system is able to keep the generations in chronological order. Outdated or obsolete generations can be automatically deleted by the operating system.

GDG in JCL
Since the DSN name is the GDG name without an appended GnnnnVnn segment each of the individual data sets or files will be processed as a contiguous file starting with the last created data set. Program Processing Overview A typical sequence of events is to submit the jobs described in Steps to Enterprise Server and then review the results. The Gnnnn is a generation number from to and the Vnn is a volume number from 00 to 99, this is typically Notice the appended segment of GV00 on the data set name.
JCL - Defining Datasets
The DSN parameter refers to the physical dataset name of a newly created or existing dataset. The DSN value can be made up of sub-names each of 1 to 8 characters length, separated by periods and of total length of 44 characters alphanumeric. This is called Backward Referencing. Concatenating Datasets If there is more than one dataset of the same format, they can be concatenated and passed as an input to the program in a single DD name.
