    False, main() is calling DD().

    More precisely there is nothing driving the behavior of DD
    correctly simulated by HHH after HHH quits simulating DD.

    The directly executed DD doesn't have to be visible to HHH,

    So you expect HHH to have psychic ability?

    HHH just needs to be passed a *description* of DD

    Yet I proved (and everyone consistently makes sure to totally

    And that different behaviour confirms the extant Halting Problem
    proofs are correct!

    /Flibble

    Not when the halting problem is corrected to be consistent with the
    way that Turing machines actually work.

    When we assume that Turing machines do not have the psychic ability
    to see the behavior of their caller, then HHH(DD)==0 is correct.

    A Halting Problem proof does not have to be predicated on Turing
    Machines.

    /Flibble

    Hence the reason why I specified this in the 100% concrete form of C
    functions. This is specific enough to prove that misconceptions are
    false. Without this degree of concrete specificity misconceptions
    forever remain as unresolved differences of opinion.

    That Heathfield does not want to bother going through the effort to
    prove to himself that he is wrong does not prove that he is right.

    No, it means there are proofs proving the Halting Problem is
    undecidable without reference to Turing Machines.

    /Flibble

    None of the conventional proofs prove halting undecidability no matter
    how they do it.

    An assertion not based in reality much like all your other baseless
    assertions.
