Nice to see that you don't disagree with what said.
Unvortunately I can't agree with what you say.
HHH terminates,
os DDD obviously terminates, too. No valid

If that iis true it means that HHH called by DDD does not return and
therefore is not a ceicder.
The directly executed HHH is a decider.
What does simulating it change about that?

It seems olcott also knows that HHH fails to reach the machine address 00002183, because it stop the simulation too soon.
No the issue is the you insist on remaining too stupid
to understand unreachable code.
void Infinite_Recursion()
{
Infinite_Recursion();
OutString("Can't possibly get here!");
}
A correct simulation by the unmodified world class simulator shows that it does reach machine address 00002183. Even HHH1 shows it. But HHH fails to machine address 00002183.
Why does olcott ignore this truth? The evidence is overwhelming.
