VM for transfer

Instruction Sets

Mnemonic	Opcode (in hex)	Other operands	Stack [before]→[after]	Description
push	-	value	[empty] → value	Pushes a value in the stack
jmp	-	N/A	label → [empty]	Jumps to the label
hlt	-	N/A		Halts the program
return	-	N/A	PC → [empty]	Returns from a subroutine

Notes

• None of the macro and actions need to return anything (unlike conventional functions), so provision for returning a value (using stack) is unnecessary
