number	instruction	argument 1	argument 2	fullname	explanation
0x00	HLT			Halt	halts the CPU
0x01	ADD	value 1	value 2	Add	ACU = value 1 + value 2
0x02	SUB	value 1	value 2	Subtract	ACU = value 1 - value 2
0x03	MUL	value 1	value 2	Multiply	ACU = value 1 * value 2
0x04	DIV	value 1	value 2	Divide	ACU = value 1 / value 2
0x05	LBS	value	amount	Left Bit-Shift	ACU = value << amount
0x06	RBS	value	amount	Right Bit-Shift	ACU = value << amount
0x07	BAN	value 1	value 2	Bitwise And	ACU = value 1 & value 2
0x08	BOR	value 1	value 2	Bitwise Or	ACU = value 1 \
0x09	BXO	value 1	value 2	Bitwise Exclusive Or	ACU = value 1 ^ value 2
0x0A	BNO	value		Bitwise Not	ACU = ~ value
0x0B	PUS	value		Push	pushes value onto the stack
0x0C	POP			Pop	pops a value from the stack and stores it in ACU
0x0D	JMP	address		Jump	jumps to address
0x0E	JEQ	address	value	Jump If Equal	jumps to address, if value is equal to ACU
0x0F	JNZ	address	value	Jump If Not Zero	jumps to address, if value is not zero
0x10	CAL	address		Call	pushes PC + 1 to the stack, then jumps to address
0x11	RET			Return	pops value from stack and jumps to it
0x12	REG	int type	address	Register Interrupt	registers int type to address
0x13	INT	int type		Interrupt	interrupts as int type
0x14	INP			Input	inputs a character into ACU
0x15	OUT	value		Output	outputs value
0x16	DIN	location		Disk In	reads value from disk at location to ACU
0x17	DOT	location	value	Disk Out	writes value to disk at location
0x18	MOV	value 1	value 2	Move	move value 2 to value 1
