BOUND - Array Index Bound Check (80188+)

        Usage:  BOUND   src,limit
        Modifies flags: None

        Array index in source register is checked against upper and lower
        bounds in memory source.  The first word located at limit is
        the lower boundary and the word at limit+2 is the upper array bound.
        Interrupt 5 occurs if the source value is less than or higher than
        the source.
