Hi Thomas,
I note that index_changed(), which has no side effects, is called with unchanged parameters twice each time around the loop. I was about to suggest saving the result of a single call and using it in both places ...
However, on first sight, it looks like the expression in the while condition will always be true (otherwise you would not reach that point in the code - you would already have returned), so we can simply remove that part of the expression (however, I didn't look too closely, so ...) :-D
ATB, Ramsay Jones
