IDIV - Signed Integer Division

	Usage:	 IDIV	src
	Modifies flags: (AF,CF,OF,PF,SF,ZF undefined)

	Signed binary division of accumulator by source.  If source is a
	byte value, AX is divided by "src" and the quotient is stored in
	AL and the remainder in AH.  If source is a word value, DX:AX is
	divided by "src", and the quotient is stored in AL and the
	remainder in DX.
