Siva, Mission Impossible-4 is a *movie*. They did not use *any* software but Photoshop and MovieMaker. Every software output written on the screens in movies is faked by more or less funny multi-media effect programs. Therefore you still see messages appearimng character by character on the screen - accompanied by a pre-historical sound of a hardware ticker.
Even the green character waterfall of The Matrix does not really represent the software output of the real-world-simulation. In fact, the characters are orange.
