A collection of tools for working with SUBLEQ one-instruction set computers.
A one-instruction set computer (OISC) is an abstract machine whose processor can only perform one operation. With a judicious choice for the single instruction (and infinite resources,) an OISC is capable of being a universal computer in the same manner as traditional computers that have multiple instructions.
SUBLEQ, "subtract and branch if less than or equal to zero," is one such instruction.
