Example

Explanation

OPENFLAG DC F'4'

The flag field is 4.

BASEINFO DS 0H BASEFLG DC XL1'80' BASEN DC CL44'BASE.CLUSTER'

X'80' (1 byte flag field) indicates that the data set name follows. The cluster name must be 44 characters padded with blanks unless the BASEFLG is X'00', in which case the BASEN field must contain 8 characters padded with blanks.

AIXINFO DS 0H AIXFLG DC XL1'80' AIXN DC CL44'DIS.CONTIG.UOUS.KEY.AIX'

X'80' indicates that the data set name follows. CL44'DIS.CONTIG.UOUS.KEY.AIX' is the alternate index name.

PROCTYP DC CL1'D'

The PROCTYP field must be a 1-character field. C'D' indicates direct processing. Use C'S' to indicate sequential processing.
