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

	Interrupt 5 occurs if the source value is less than or higher than
	the source.
