When we assume that:
(a) HHH is an x86 emulator that is in the same memory space as DDD.
(b) HHH emulates DDD according to the semantics of the x86 language.

Yes, we see. In fact DDD is not needed at all.

You should also point a link to the equivocation fallacy. You use it
more often than straw man.

Your first posting looked like you were going to apply equivocation
later in the discussion. Now, after several later messages, it seems
that you want to apply the fallacy of "moving the goal posts" instead.

Which is incorrect, because HHH is not allowed to change the input. The simulating HHH may abort, but it may not ignore the fact that the input (the simulated HHH) is coded to abort when it sees the 'special condition'. Otherwise it would decide about a non-input, which is not allowed.

No DDD ever reaches its "return" instruction no matter
what-the-Hell that HHH does,

Exactly. Do you finally understand that HHH cannot possibly simulate itself up to the end?

 *That seems to be a stupid (ignoramus) thing to say*

No THAT was a stupid thing to say.

 DDD forces emulated HHH to remain stuck in recursive
simulation forcing the emulated HHH to never reach
its own final halt state.

No, DDD can do nothibg to affect the behavior of HHH, getting stuck would purely be an error on HHH's part, which you have made sure it doesn't, so neither does DDD.

 Do you have at least a BS degree in CS? Richard does not.
 

No, I do not have a BS in CS, it is a Masters. YOU are the one that seems to have a "BS" (as in BULL SHIT) in Computer Science.
