Direct Allocation Using JCL

You can directly allocate VSAM data sets through JCL.

The following example allocates a new data set and, with DATACLAS, uses the allocation attributes predetermined by the storage administrator through the ACS routines.
//DD1     DD DSNAME=EXAMPLE1,DATACLAS=DCLAS01,
//        DISP=(NEW,KEEP)

See z/OS MVS JCL User's Guide and z/OS MVS JCL Reference for information about JCL keywords.
