I like this idea, but I'm changing my mind,*maybe is better to keep the 
current way*, its not really needed to declare a variable inside the 
codes, its nice, I like it but its not really necessary.

But something that has been pointed (by Joerg I belive) is the 
initialization of variables, what about it? This would be a nice thing 
and I don't see why not. I prefer to see:

*var
    X: Integer = 0;
    Y: Integer = 100;*

than

*var
   X: Integer;
   Y: Integer;
begin
   X := 0;
   Y := 100;*
