Actually, yes it must. Computers are infernally stupid. They are like vulcans when logic is concerned. They cannot think for themselves. They do exactly as they are told. Also, ever computer task is a combination of extremely simple artihmatic. Therefor yes, when something is true on one system, provided nothing weird happens, it must be true on all systems. Same logic applies by saying that if something works one way on everyone's system, and the other way on your system, then you have a strange system, and your input in discussions is then pointless since no one can use it.
But I already said that before...
Of course if you have something to contribute, you are welcome to do so, but in a discussion about programming, "something to cvontribute" includes arguments, which are codes that show what you mean, that support your statements, etc, and not "It works that way on my system".
