Pathological self-reference changes the semantics of the same finite string.

The same thing applies to this more complex example that
is simply over-the-head of most reviewers:

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

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

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.
This sentence is not true: "This sentence is not true"
The exact same (finite string) sentence applied to a
copy of itself becomes true because the inner sentence
is not a truth-bearer.

Fred thinks the when DDD is emulated by HHH according to
the semantics of the x86 language and this causes an
emulated HHH to not halt then the emulation is wrong.

 Olcott has a strange problem with the English language. He is unable to express himself. When he talks about what other people say, they never recognize themselves in his words. When he talks about other things he always expresses himself in self-contradictory ways. It is not clear to me whether this is only a problem in expressing himself, it looks as if he also has a problem in understanding English.
 I never said such a thing.
I said that a finite string has a unique meaning according to the semantics of the x86 language.

I just proved that the basic notion of finite strings
having unique meanings independently of their context
is incorrect.
Anyone that studies linguistic meaning knows that context
does change the meaning. That you are ignorant of this
IS NOT MY MISTAKE !!!
