As you have been told MANY times, the step after the 0000217a call HHH, 
should have been the emulation of the instruction at 000015d2, the first 
instruction of the subroutine HHH that is part of the program DDD.

That you don't understand what a "correct emulation" is, what the 
semantics of the x86 instructions set is, what a "program" is, or 
anything related just proves your ignorance and inability to learn basic 
facts.

Sorry, you are just PROVING that fact, and that you are NOTHING but a 
pathetic ignorant pathological lying idiot.
