All temporary SMS-managed data sets must either have a name (DSNAME value) that starts with with & or && or have no name.
Non-VSAM temporary data sets are the only uncataloged data sets that you can create.

For more information about temporary data sets, see z/OS MVS JCL Reference. For more information about VSAM temporary data sets, see z/OS DFSMS Using Data Sets.
You cannot concurrently allocate data sets that reside on the same physical tape volume.
For allocation of a generation data group member, provide the fully qualified data set name, including the generation number.

FILE(ddname)

Specifies the name of a data definition (DD) statement, which can be up to eight characters long. If you omit this parameter, the system assigns an available system file name. Do not use special DD names unless you want to use the facilities that those names represent to the system. For more information about AMSDUMP, see z/OS DFSMS Access Method Services Commands. For more information about the following special DD names, see z/OS MVS JCL Reference:

AMSDUMP         SYSABEND
JOBCAT          SYSCHK
JOBLIB          SYSCKEOV
STEPCAT         SYSMDUMP
STEPLIB         SYSUDUMP

For more information about these special DD names, see z/OS TSO/E Command Reference:

You cannot use SYSTSIN and SYSTSPRT in a job step that runs the ALLOCATE command. See Restrictions for further information.
