DD
Initiates a direct retrieval of the data set whose DSN matches DYNRQDSN. If a
generation or version selection field is specified (DYNRQVER, DYNRQGEN,
DYNRQGDG, or DYNRQVOL) the appropriate generation will be returned.
Otherwise, the most current generation will be returned.
If DYNRQDVC is specified, only data sets and versions of the required device
class will be returned. If DYNRQVSQ is specified, volumes starting at the
volume sequence number specified are returned. Otherwise volumes starting
with the first volume for the version are returned. As many volumes as exist
and fit in DYNINFO are returned in one call.
If more volumes or extents exist than will fit, DYNRTCOD is set to 28.
DYGNVOL always contains the number actually returned. DYGVOLS always
contains the total number active for the version. DYNRTLEN contains the
DYNINFO length in bytes required to hold all volumes available, starting at the
specified volume sequence number.
