 People here that are experts in the C programming language know that
*P correctly simulated by H cannot possibly stop running unless aborted*
yet lie about this or to try to get away with the strawman deception
CHANGE-THE-SUBJECT fake rebuttal.

 People here who have recently followed these discussions know that "P
correctly simulated by H cannot possibly stop running unless aborted"
does not confirm or contradict anything Linz and Strachey have said.
 

 When P correctly simulated by H meets this criteria
   If simulating halt decider H correctly simulates its input P
   until H correctly determines that its simulated P would never
   stop running unless aborted then
    H can abort its simulation of P and correctly report that P
   specifies a non-halting sequence of configurations.
 My first paper in simulating halt deciders has all of the details
including showing the execution trace of P correctly simulated
by H proves a repeating state thus meets the above criteria:
