                 incx, double *dy, long incy);



PURPOSE
       dqdoti computes a constant plus the double precision dot product  of  x
       and y where x and y are double precision n-vectors.


ARGUMENTS
       N (input)
                 On  entry,  N specifies the number of elements in the vector.
                 If N <= 0 then the function returns the value DB.   Unchanged
                 on exit.


       DB (input)
                 On  entry,  the  constant  that  is  added to the dot product
                 before the result is returned.  Unchanged on exit.


       QC (output)
                 On exit, the extended precision result.


       DX (input)
                 On entry, the incremented array DX must contain the vector x.
                 Unchanged on exit.


       INCX (input)
                 On  entry,  INCX  specifies the increment for the elements of
                 DX.  Unchanged on exit.


       DY (input)
                 On entry, the incremented array DY must contain the vector y.
                 Unchanged on exit.


       INCY (input)
                 On  entry,  INCY  specifies the increment for the elements of
                 DY.  Unchanged on exit.


Note:
       dqdoti does not exist in X86 libraries.
