This example shows the ALLOCATE command being used to allocate a non-VSAM data set. ALLOCATE, unlike DEFINE NONVSAM, lets you give the SMS classes for a non-VSAM data set.

//ALLOC    JOB  ...
//STEP1    EXEC PGM=IDCAMS
//SYSPRINT DD   SYSOUT=A
//SYSABEND DD   SYSOUT=A
 /SYSIN    DD   *
     ALLOC -
           DSNAME(NONVSAM.EXAMPLE) -
           NEW -
           DATACLAS(PS000000) -
           MGMTCLAS(S1P01M01) -
           STORCLAS(S1P01S01)
/*

The parameters are:

• DSNAME specifies that the name of the data set to be allocated is NONVSAM.EXAMPLE.
• NEW creates the data set does.is
• DATACLAS assigns an installation-defined name (PS000000) of a data class to this new data set. This parameter is optional and, if not used, the data set assumes the default data class assigned by the ACS routines.
• MGMTCLAS assigns an installation-defined name (S1P01M01) of a management class to this new data set. The data set assumes the migration and backup criteria assigned to this management class by the ACS routines. This parameter is optional and, if not used, the data set assumes the default management class assigned by the ACS routines.
• STORCLAS assigns an installation-defined name (S1P01S01) of a storage class to this new data set. This storage class and the ACS routines determine the volume. This parameter is optional and, if not used, the data set assumes the default storage class assigned by the ACS routines.
