In other words no HHH of the set of HHH/DDD pairs ever succeeds to
complete the simulation of a halting program. Failure to reach the end
of a halting program is not a great success. If all HHH in this set
fail, it would be better to change your mind and start working on
something more useful.

 He seems to think that he's written a program that detects that
his thing hasn't 'reached its "return" instruction and
terminate[d] normally', given some number of steps, where that
number is ... the cardinality of the natural numbers.
 I wonder if he knows that the set of natural numbers is
infintite, though I suspect he'd say something like, "but it's
countable!"  To which I'd surmise that he has no idea what that
means.
 

void DDD()
{
   HHH(DDD);
   return;
}
Everyone here knows that when N steps of DDD are correctly
simulated by HHH that DDD never reaches its own "return"
instruction and terminates normally thus never halts.
*AND THEY LIE ABOUT IT BY ENDLESSLY CHANGING THE SUBJECT*
My posthumous reviewers will condemn them.
When DDD is correctly simulated by HHH once the behavior
of DDD exactly matches the infinite recursion behavior
pattern.
int DD()
{
   int Halt_Status = HHH(DD);
   if (Halt_Status)
     HERE: goto HERE;
   return Halt_Status;
}
We have the exact same effect when N steps of DD
are correctly emulated by HHH. I created DDD because
some of my reviewers are not technically competent
enough to see that line 2 of DD is unreachable code
when N steps of DD are correctly simulated by HHH.

I plonked Olcott a few years ago, yet I see dozens of posts a
day a day of people replying to him.
 I gather, based on reading the quoted text, that he is near the
end of a battle with cancer; that's very sad.  Perhaps he should
spend what time remains to him with friends and family, and less
arguing with strangers on USENET.  Maybe we could all help him
in this endeavor by not responding.  I, for one, intend to take
my own advice after this post.
