NAME
DLA_WWADDW  DLA_WWADDW add a vector W into a doubledsingle vector (X, Y)
SYNOPSIS
 SUBROUTINE DLA_WWADDW(

N, X, Y, W )

IMPLICIT
NONE

INTEGER
N

DOUBLE
PRECISION X( * ), Y( * ), W( * )
PURPOSE
DLA_WWADDW adds a vector W into a doubledsingle vector
(X, Y).
This works for all extant IBMaqs hex and binary floating point
arithmetics, but not for decimal.
ARGUMENTS
 N (input) INTEGER

The length of vectors X, Y, and W.
X, Y (input/output) DOUBLE PRECISION array, length N
The doubledsingle accumulation vector.
 W (input) DOUBLE PRECISION array, length N

The vector to be added.
