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