     INTEGER               RECNO

Brief_I/O

     VARIABLE  I/O  DESCRIPTION
     --------  ---  --------------------------------------------------
     RECNO,
     WORDNO     I   Record, word numbers of a location within DAF.
     ADDR       O   Corresponding address.

Detailed_Input

     RECNO,
     WORDNO   are the record and word numbers of an arbitrary
              location within a DAF.

Detailed_Output

     ADDR     is the corresponding address within the DAF.

Parameters

     None.

Exceptions

     1)  If either RECNO or WORDNO is zero or negative, the error
         SPICE(DAFNOSUCHADDR) is signaled.

Files

     None.

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.
