ALTD ("A" Column) Symbol Key

Flag	Description
f	ALTD selects alternate flags
fr	ALTD selects alternate flags and register
r	ALTD selects alternate register
s	ALTD operation is a special case

IOI and IOE ("I" Column) Symbol Key

Flag	Description
b	IOI and IOE affect source and destination
d	IOI and IOE affect destination
s	IOI and IOE affect source

Flag Register Key

S	Z	L/V1	C	Description
*				Sign flag affected
-				Sign flag not affected
	*			Zero flag affected
	-			Zero flag not affected
		L		L/V flag contains logical check result
		V		L/V flag contains arithmetic overflow result
		0		L/V flag is cleared
		*		L/V flag is affected
			*	Carry flag is affected
			-	Carry flag is not affected
			0	Carry flag is cleared
			1	Carry flag is set

1 The L/V (logical/overflow) flag serves a dual purpose--L/V is set to 1 for logical operations if any of the four most significant bits of the result are 1, and L/V is reset to 0 if all four of the most significant bits of the result are 0.
