    //Entry point of Program
    static public void Main()
    {
        Directions[] direction = { Directions.WEST,Directions.SOUTH,Directions.EAST };

        //EAST   0  00

        //NORTH  2  10
        //SOUTH  3  11

        foreach (Directions dir in direction)
        {
            Console.WriteLine("High bits:");
            if (dir.HasFlag(Directions.WEST))
                Console.WriteLine("\tWEST");
