Nope, it is just the correct PARTIAL emulation of the first N
instructions of DDD, and not of all of DDD,
That is what I said dufuss.
You were trying to label an incomplete/partial/aborted simulation as
correct.

Nope, if a HHH returns to its caller,

how *HHH* returns

Of course. I made it only to illustrate one step in the paradoxical

It is like I always pointed out. The outer HHH cannot
wait for the inner ones to abort because it would be
waiting forever.
Exactly. And when it aborts, it aborts too soon, one cycle before the simulated HHH would abort and halt.

For the record, I did no such thing and Fred is correct.

It is clear that olcott does not really read what I write. (Or is very short of memory.)
I never said such a thing.
I repeatedly told that the simulating HHH aborted when the simulated HHH had only one cycle to go. I never said that the simulated HHH reached it abort and halted.
In fact, I said that the fact that the simulation fails to reach the abort and halt of the simulated HHH proves that the simulation is incomplete and incorrect, because a complete simulation (such as by HHH1) shows that the simulated HHH would abort and halt.
It now becomes clear that you either never understood what I said, or your memory is indeed very short.
Give it some time to think about what I say, try to escape from rebuttal mode, instead of ignoring it immediately.
