Catalog a non-VSAM or non-system-managed data set, or data sets on a system-managed tape volume,
by specifying CATLG as the disposition.(The system automatically catalogs
VSAM and system-managed DASD data sets when they are allocated.)
For a new data set, the system keeps the data set
and creates an entry pointing to it in the system-determined catalog.
For an old data set, the system keeps the data set, and does the
following depending on the parameters on the DD statement.
- If UNIT and VOLUME=SER are not coded, the system updates the catalog
that is used to locate the data set.
- If UNIT and VOLUME=SER are coded, the system creates a new catalog
entry in the applicable system master or private catalog, even if
the data set is already cataloged.
