Organizing a Direct Data Set z/OS DFSMS Using Data Sets SC23-6855-00 |
|
In a direct data set, there is a relationship between a control number (or identification of each record) and its location on the direct access volume. Therefore, you can access a record without an index search. You determine the actual organization of the data set. You can use direct addressing to develop the organization of your data set. When you use direct addresses, the location of each record in the data set is known. |
