subroutine dla_wwaddw (N, X, Y, W)
DLA_WWADDW adds a vector into a doubled-single vector.

DLA_WWADDW adds a vector into a doubled-single vector.  

Purpose:

    DLA_WWADDW adds a vector W into a doubled-single vector (X, Y).

    This works for all extant IBM's hex and binary floating point
    arithmetics, but not for decimal.

Parameters:

N

          N is INTEGER
            The length of vectors X, Y, and W.

X

          X is DOUBLE PRECISION array, dimension (N)
            The first part of the doubled-single accumulation vector.

Y

          Y is DOUBLE PRECISION array, dimension (N)
            The second part of the doubled-single accumulation vector.

W

          W is DOUBLE PRECISION array, dimension (N)
            The vector to be added.
