PURPOSE
       sdsdot Computes a constant plus the double precision dot product  of  x
       and y where x and y are single precision n-vectors.


ARGUMENTS
       N (input)
                 On  entry,  N specifies the number of elements in the vector.
                 If N is not positive then the function returns the value 0.0.
                 Unchanged on exit.


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


       SX (input)
                 ( 1 + ( n - 1 )*abs( INCX ) ).   On  entry,  the  incremented
                 array SX must contain the vector x.  Unchanged on exit.


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


       SY (input)
                 ( 1 + ( n - 1 )*abs( INCY ) ).   On  entry,  the  incremented
                 array SY must contain the vector y.  Unchanged on exit.


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