The following example uses the ALLOCATE command to allocate a non-VSAM data set. ALLOCATE, unlike DEFINE NONVSAM, lets you specify 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)
