REFDD parameter z/OS MVS JCL Reference SA23-1385-00 |
|
Parameter type Keyword, optional — use this parameter only with SMS Without SMS, use the DCB=*.ddname form of the DCB parameter described in Subparameter definition. Purpose Use the REFDD parameter to specify attributes for a new data set by copying attributes of a data set defined on an earlier DD statement in the same job. The following attributes are copied to the new data set from (1)
the attributes specified on the referenced DD statement, and (2) for
attributes not specified on the referenced DD statement, from the
data class of the data set specified by the referenced DD statement:
Only RECFM and LRECL apply to tape data sets. REFDD does not copy DCB attributes from the data set label. See the DD LIKE parameter. If SMS is not installed or is not active, the system checks the syntax and then ignores the REFDD parameter. The retention period (RETPD) or expiration date (EXPDT) is not copied to the new data set. Note: Do not use the REFDD parameter to copy attributes from a temporary
data set (&&dsname), partitioned data set if a member name
is included, and relative generation number for a GDG.
