I think you're wrong, here.  All your C programs are a stand in
for turing machines.  A turing machine is either running or
halted.  There is no third state "aborted".

Until you take the conventional ideas of
(a) UTM
(b) TM Description
(c) Decider
and combine them together to become a simulating partial halt decider.

Where does the notion of "aborted", as being distinct from halted, come
from?

After all of these years and you don't get that?

"Aborted" being distinct from halted is an incoherent notion.  It isn't
consistent with turing machines.  I was hoping you could give a
justification for it.

A simulating partial halt decider can stop simulating
its input when it detects a non-halting behavior pattern.
This does not count as the input halting.

Says who?  Well, OK, it would be the machine halting, not the input, but
that's a small point.

void Infinite_Recursion()
{
   Infinite_Recursion();
}

[ .... ]

Do you understand that HHH(Infinite_Recursion) correctly
implements this criteria for the above input?

There's nothing wrong with my understanding, but I'm not sure what
"implementing a criterion (not "criteria")" means,

[ .... ]

HHH correctly simulates Infinite_Recursion until it correctly
detects a the non-halting behavior pattern that every programmer
can see.

You dodged the question about whether you can see this
non-halting behavior pattern on the basis of this x86 code:

It was an incoherent question.  What on Earth does "implementing a
criterion" even mean?  But I told you there's nothing amiss with my
understanding.

[ .... ]

You've got nothing more to say on my point, that the "aborted" state is
the same thing as the "halted" state?
