Particulars

     To the user, the data in a DAF appear to be a contiguous
     collection of double precision numbers, each of which has an
     address. To the DAF software, however, the data appear to be
     a collection of records, each containing 128 double precision
     words. The routines DAFARW and DAFRWA translate between these
     two representations.

Examples

     Routines DAFRDA and DAFWDA illustrate the use of DAFARW and
     DAFRWA.

Restrictions

     None.

Literature_References

     None.
