Nope, that just show you are using an improperly defined term, as it isn't "correct" > > DD correctly emulated by HHH cannot possibly > reach its "return" instruction final halt state. No, "DD correctly emulated by HHH" is just a fantasy of ylur mind, and thhus not a valid basis to talk about anything, After all, you have insisted on a definiton of HHH, as it is defined in Halt7.c, and it doesn't do what you claim HHH must do, thus all you are doing is proving you are just a pathological liar. > > You must be imagining that DD emulated by HHH > leaps over the "call" instruction and jumps > straight to the "ret" instruction. No, HHH just incorrectly stops its emulation, making your claims of a DD correctly emulated by HHGH just a pathological lie out that comes out of your ignorant imagination. >
