 HHH computes the mapping from DDD to behavior that never reaches
its "return" statement on the basis of the x86 emulation of DDD
by HHH according to the semantics of the x86 language.
 For all the  years people said that this simulation is incorrect
never realizing that they were disagreeing with the semantics
of the x86 language.
 Now that I point this out all that I get for "rebuttal" is bluster
and double talk.
 The same thing applies to this more complex example that
is simply over-the-head of most reviewers:
 int DD()
{
   int Halt_Status = HHH(DD);
   if (Halt_Status)
     HERE: goto HERE;
   return Halt_Status;
}

 Nice to see that you don't disagree.
But you should not use subject lines that are off-topic for the group.
 

 When a specific reviewer makes a specific mistake in
reviewing my work related to this group I must refer
to that specific reviewer's mistake to clear my name.
 I could generalize it. No one person here besides myself
sufficiently understands the details of how a simulating
halt decider computes the mapping from an input finite
string to the behavior that this finite sting specifies.

 It looks more that you are the only person that does not understand these details, but who thinks that his dreams are a nice substitute for facts.
 

 I specifically referred to Ben because he got everything
else correctly. Most everyone else cannot even understand
that correct simulation is defined by HHH emulating DDD
according to the semantics of the x86 language.

 Olcott does not even understand what the semantics of the x86 language is. He thinks that a finite string can have different behaviours according to the semantics of the x86 language, depending on whether it is directly executed, or simulated by different simulators, where the semantics could be different for each simulator.
 

 Pathological self-reference DOES CHANGE THE SEMANTICS.

"This sentence is not true" is neither true nor false
because it is not a truth bearer.
