You do not need to create a model DSCB if you can refer to a cataloged
data set whose attributes are identical to those you desire. You can
refer to the cataloged data set's DCB attributes by referring to its
DCB or to the DD statement that allocated it.
To refer to a cataloged data set for the use of its attributes,
you can specify one of the following on the DD statement that creates
and catalogs your generation:
- DCB=(dsname), where dsname is the name
of the cataloged data set.
- LIKE=dsname, where dsname is the name
of the cataloged data set.
- REFDD=ddname, where ddname is the name
of a DD statement that allocated the cataloged data set.
