Explanation: ORIGINALVOLUMES(ovol1...ovoln) is a required parameter (if you are specifying which volumes are to be copied) requesting that alternate tape volume copies be created. The volumes to be copied are specified by their volume serial numbers (ovol). The alternate tape volumes are made even though the original volumes may not be marked full or may already have an alternate tape volume reference in the OCDS TTOC record.
The optional parameter ALTERNATEVOLUMES may be used to specify which output volumes are to be used in place of using scratch tapes. If specified, the number of entries in ORIGINALVOLUMES and ALTERNATEVOLUMES must match. The TAPECOPY function will maintain a one-for-one correspondence between the two sets of entries.
Defaults: None.
