OPEN/EOV Exit Processing z/OS DFSMS Using Data Sets SC23-6855-00 |
|
If the program has a DCB OPEN exit, it is called only at the beginning of the first data set. With like concatenation, if the program has an end-of-volume exit, it is called at the beginning of each volume of each data set except the first volume of the first data set. If the type of data set does not have volumes, the system treats it as having one volume. |
