SMPWRK4

ddname
SMPWRK4.
Use
The SMPWRK4 data set is used as temporary storage for IMASPZAP and link-edit input containing EXPAND control statements.
Attributes
Partitioned; LRECL=80, BLKSIZE=multiple of 80, RECFM=FB, DISP=(NEW,DELETE).

Specifying DISP=(NEW,DELETE) minimizes space loss problems. SMPWRK4 is generally needed only for the duration of the SMP/E job step. To keep the data set longer than that, you must use a different DISP value and compress the data set to reclaim space.

The SMS-related options DATACLAS, MGMTCLAS, STORCLAS, and DSNTYPE provide additional data set support. For more information, refer to z/OS DFSMS Using Data Sets.

Device
Direct access only.
Note:
  1. BLKSIZE must not exceed 32760.
  2. If the BLKSIZE value is omitted or inapplicable, SMP/E uses a default of 0 which allows the system to determine the most appropriate block size.
