(unless you hit what you define as a terminal instruction for the program, in which chase the program is "Halting") Also, call instruction need to be followed by the actual instruction by instruciton emulation of the code that is called. You don't follow either of those, so your emulations are not correct. And you just prove yourself to be a pathological liar.
