It is an old habit of mine to do so. The point is that Decrementing is
faster than Incrementing - it probably does not do much of a difference
here, but I try to do so all the time, as it might help me some day.
Actually Delphi counts down to in for loops, where the var itself is
not used, cause it is faster.

sorry I was commenting something else, it went wrong here
