Re: Can you see that D correctly simulated by H remains stuck in recursive simulation?

The above template refers to an infinite set of H/D pairs where D is
correctly simulated by pure function H. This was done because many
reviewers used the shell game ploy to endlessly switch which H/D pair
was being referred to.

    This is provided because every reviewer had a different notion of
    correct simulation that diverges from this notion.

*Execution Trace*
    Line 11: main() invokes H(D,D); H(D,D) simulates lines 01, 02, and 03
    of D. This invokes H(D,D) again to repeat the process in endless
    recursive simulation.

By your definiton of "Correct Simulation", you do realize that you have broken connection between the simulaiton not completing and the program described by the input not halting?

In other words you are requiring that the x86 instructions of D

No, they must be simulated COMPLETELY.

 And this is where your lies start.
 

I WILL NO LONGER TOLERATE THE STRAW-MAN DECEPTION CHANGE THE
SUBJECT FAKE REBUTTAL THAT PREVENTS ANY CLOSURE ON ANY POINTS.
WE CAN GET TO THE OTHER POINTS ONLY WHEN WE ARE DONE WITH THIS ONE.
THE SUBJECT OF THE THREAD IS THE POINT OF THIS THREAD
