I can't really do that when I refer to an infinite set of H/D pairs
based on a C programming template.

This is the actual code that does compile.

typedef int (*ptr)();
int H(ptr P, ptr I);

int D(ptr x)
{
   int Halt_Status = H(x, x);
   if (Halt_Status)
     HERE: goto HERE;
   return Halt_Status;
}

int main()
{
   H(D,D);
   return 0;
}

H is the infinite set of every H that correctly simulates
N steps of D.

I had to refer to line numbers to show the exact
execution trace. I can't do that without line numbers.

People were acting like I was totally clueless. I had a hard
time writing the code to translate control flow instructions
of C until I found out about
https://en.wikipedia.org/wiki/Abstract_syntax_tree
Then it was easy.

I am only asking about the behavior of a single
C function template.
