IMHO the #for loop goes to the end value if reaches it e.g.:
#for (I, 1, 10)
#warning Str(I)
#end
will show all the numbers from 1 up to 10, but :
#for (I, 1, 10, 2)
#warning Str(I)
#end
will only show 1, 3, 5, 7, 9 because the 11 that follows is greater than 10.
On the other hand a #while (I<10) statement will only show the numbers up to 9
because the symbol "<" means *strictly* smaller than. If you want 10 to show up
you should use #while (I<=10).
