       INTEGER N, INCX, INCY
       DOUBLE PRECISION X(*), Y(*)

       SUBROUTINE DCOPY_64(N, X, INCX, Y, INCY)

       SUBROUTINE COPY(N, X, INCX, Y, INCY)

       INTEGER :: N, INCX, INCY
       REAL(8), DIMENSION(:) :: X, Y

       SUBROUTINE COPY_64(N, X, INCX, Y, INCY)

       INTEGER(8) :: N, INCX, INCY
       REAL(8), DIMENSION(:) :: X, Y




   C INTERFACE
       #include <sunperf.h>

       void dcopy(int n, double *x, int incx, double *y, int incy);

       void dcopy_64(long n, double *x, long incx, double *y, long incy);



PURPOSE
       dcopy Copy x to y where x and y are n-vectors.


ARGUMENTS
       N (input)
                 On  entry,  N specifies the number of elements in the vector.
                 N must be at least one for the subroutine to have any visible
                 effect.  Unchanged on exit.


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


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


       Y (output)
                 (  1  +  (  n - 1 )*abs( INCY ) ).  On entry, the incremented
                 array Y must contain the vector y. On exit, Y is  overwritten
                 by the vector x.


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