I\'ve read \"what-is-turing-complete\" and the wikipedia page, but I\'m less interested in a formal proof than in the practical implications of being Turing Complete.
You can try emulating an OISC (One Instruction-Set Computer). If you can emulate one of the instructions there, then since those single instruction can be used to compose a Turing Complete machine, then you have proven that your language must be Turing Complete as well.
