NAME

     scopy - Copy x to y

SYNOPSIS

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

     INTEGER N, INCX, INCY
     REAL X(*), Y(*)

     SUBROUTINE SCOPY_64(N, X, INCX, Y, INCY)

     INTEGER*8 N, INCX, INCY
     REAL X(*), Y(*)

  F95 INTERFACE
     SUBROUTINE COPY([N], X, [INCX], Y, [INCY])

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

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

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

  C INTERFACE
     #include <sunperf.h>

     void scopy(int n, float *x, int incx, float *y, int incy);

     void scopy_64(long n, float *x, long incx,  float  *y,  long
               incy);

PURPOSE

     scopy 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 sub-
               routine 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.
