 When finite integer N instructions of the above x86
machine language DD are emulated by each x86 emulator
EEE[N] at machine address [000015c3] according to the
semantics of the x86 language no DD ever reaches its own
"ret" instruction at machine address [00002155] and
terminates normally.
 

 Your can't emulate the above code for N > 4, as you get into undefine memory.
 

 I have already addressed this objection dozens of times.
 

 No you haven't. You have given several different LIES about it.
 As I have pointed out, if you don't include Halt7.c as part of the definition, then you can't do it as you are looking at undefined memory.
 

 Your lack of technical competence is showing.
(1) We are talking about a hypothetical infinite
set of pure x86 emulators that have no decider code.
 (2) The memory space of x86 machine code is not
in the C source file, it is in the object file.

 It isn't in the object file, either. Only the initial values of some
memory locations are there. The object file does not even specify
where in the memory space those locations are. The execution of a
program requires a memory space larger than the object file.
 

 I patch the Halt7.obj file so that functions
are at a fixed address. This file is never linked.

 Doesn't affect the fact that important parts of the memory space are not
containted in the object file.

 Richard stupidly complained that III could not call EEE
because he stupidly believed that there were in different
memory spaces.
