field to allow him to claim what he wants.Here one can claim whatever one wants anysay.
In if one wants to present ones claims on some significant forum then
it is better to stick to usual definitions as much as possible.Sort of like his new definition of H as an "unconventional" machine
that some how both returns an answer but also keeps on running.There are systems where that is possible but unsolvable problems are
unsolvable even in those systems.When Ĥ is applied to ⟨Ĥ⟩
Ĥ.q0 ⟨Ĥ⟩ ⊢* embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qy ∞
Ĥ.q0 ⟨Ĥ⟩ ⊢* embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qnThis notation does not work with machines that can, or have parts
that can, return a value without (or before) termination.00 int H(ptr x, ptr x) // ptr is pointer to int function
01 int D(ptr x)
02 {
03 int Halt_Status = H(x, x);

06 return Halt_Status;

09 int main()

12 }In any case you diverged away form the whole point of this thread.Yes, in the same way that you are wrong. The above "C code" is garbage;
Richard is wrong when he says that there exists an H/D pair such
that D simulated by H ever reaches past its own line 03.
as already pointed out, it doesn't even compile. So any talk of
"reaching line 3" or "matching" that "code" is vacuous nonsense.
by the same H(D,D) that it calls cannot possibly reach past its own
line 03. Simple software engineering verified fact.

Olcott is trying to stay at this point for several weeks now, but he does not succeed. The reason probably is, that it is already a few steps too far. First there must be agreement about the words and terms used in what he says. So, we should delay this subject and go back a few steps.I am ONLY referring to expressions that are PROVEN
Before we can talk about this, first there must be 100% agreement about:
1) What is a "verified fact"? Who needs to do the verification before it can be said that it is a verified fact?
to be {true entirely on the basis of their meaning}.
*CONCRETE EXAMPLES*
How do we know that 2 + 3 = 5?
But nobody here knows the proof for your assertion above, that it is a verified fact that it cannot reach past line 03. So, we would like to see that proof. Just the claim that it has been proven is not enough.
about the semantics of the C programming language.
If you knew C will enough yourself you would comprehend
that my claim about:
Any H/D pair matching the above template where
D(D) is simulated by the same H(D,D) that it calls
cannot possibly reach past its own line 03.
This is a simple software engineering verified fact.
