I repeatedly showed the failure of HHH to reach the 'ret' instruction of 
the finite string that is its input, where the direct execution and 
other simulators have no problem with exactly the same finite string to 
reach this 'ret' instruction.

Olcott claims that HHH does not fail to reach this 'ret' instruction.


If this was not stupidly wrong you could show
all of the steps of DD correctly emulated by HHH
that reaches its own "ret" instruction.

You cannot do that because:
(a) You know that you are wrong
(b) You do not understand these things

I don't understand why Olcott keeps repeating the failure of HHH to 
reach the 'ret' instruction.
