I don't understand what difference it makes if I assign I :=0 with the variable declaration or If I was using I for something else.. It's irrelevant what the condition of I was before the for loop, just as it's irrelevant that the status of a variable is before you assign it to something. I just don't think this should produce any kind of an error, I'm not doing anything technically wrong as far as I can tell. I should be able to use I for a whole pile of things then re-cycle it in my for loop.. then use it for more stuff after.. the condition of I before or after the for loop is irrelevant, as long as I make sure I initialize it before using it.. everything should be fine. I should be able to do this if I want:
Var I : Longint = 57; Begin Inc(I); Writeln(I); I:=50; Inc(I); Writeln(I); For I := 1 to 6 Do Writeln(I); I:=-10; Inc(I); Writeln(I); End. It should not matter what I was using I for before or after the for loop or if it was initialized or used for some other purpose before or after the loop.

James question is about the difference between an initialized global var and a non initialized global var. My guess is that it has to do with the different exe/linker sections where these vars are put. Hopefully some compiler guru can explain.
