Virtual Machine Instruction RSM

Mnemonic: RSM

Hex Code:	20	01	00	00	00	00	HH	10	unconditional
	20	M1	00	XX	00	YY	HH	10	M=1-7, Compare register XX to register YY
	20	M1	00	XX	KK	KK	HH	10	M=9-F, Compare register XX to constant KKKK

Action:	The RSM command resumes at the location where playback was suspended by a CallSS or MenuCall (user pressed a menu button) operation, and can set SPRM 8 to highlight a different button by setting "HH" (byte 6) to 4*button.
Order:	If a compare is specified, it is performed first. If the conditions are met the RSM is executed.
Comments:	The destination is not restricted to the current domain. The CallSS command can alter the resume cell number on entry to the menu. This command is also available as part of class 4, 5, and 6 commands.

Compare operation codes
register to register		register to constant		Alternate mnemonic	Comments
M	operation	M	operation	Alternate mnemonic	Comments
1	RegX & RegY	9	RegX & K	BC	Bitwise compare, the two operands are anded, if the result is non-zero the condition is true
2	RegX == RegY	A	RegX == K	EQ	If the two operands are equal the condition is true
3	RegX != RegY	B	RegX != K	NE	If the two operands are not equal the condition is true
4	RegX >= RegY	C	RegX >= K	GE	If RegX is greater than or equal to the right operand the condition is true
5	RegX > RegY	D	RegX > K	GT	If RegX is greater than the right operand the condition is true
6	RegX <= RegY	E	RegX <= K	LE	If RegX is less than or equal to the right operand the condition is true
7	RegX < RegY	F	RegX < K	LT	If RegX is less than the right operand the condition is true

Register Codes
0x00 through 0x0F	General Purpose registers 0 to 15 (GPRM)
0x80 through 0x97	System Parameter registers 0 to 23 (SPRM)
