Instruction Set

JGE	Jump if greater or equal
Syntax	JGE	label
Operation	If (N .XOR. V) = 0 then jump to label: PC + 2 ⋅ offset −> PC
	If (N .XOR. V) = 1 then execute the following instruction
Description	The status register negative bit (N) and overflow bit (V) are tested. If both N
	and V are set or reset, the 10-bit signed offset contained in the instruction LSBs
	is added to the program counter. If only one is set, the instruction following the
	jump is executed.
	This allows comparison of signed integers.
Status Bits	Status bits are not affected.
Example	When the content of R6 is greater or equal to the memory pointed to by R7,
	the program continues at label EDE.
	CMP	@R7,R6	; R6 ≥ (R7)?, compare on signed numbers
	JGE	EDE	; Yes, R6 ≥ (R7)
	......		; No, proceed
