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

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

       SUBROUTINE SSWAP_64(N, X, INCX, Y, INCY)

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




   F95 INTERFACE
       SUBROUTINE SWAP(N, X, INCX, Y, INCY)

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

       SUBROUTINE SWAP_64(N, X, INCX, Y, INCY)

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




   C INTERFACE
       #include <sunperf.h>

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

       void sswap_64(long n, float *x, long incx, float *y, long incy);



PURPOSE
       sswap Exchange x and 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/output)
                 (  1  +  (  n - 1 )*abs( INCX ) ).  On entry, the incremented
                 array X must contain the vector x.  On exit, the y vector.


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


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


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