The other suggestions you have received are good places to start.  I'd =
add only one other - that you consider running the code inside an IDE =
and single-stepping through as you watch what happens to the variables.  =
As you get a better and better feel for what the code is doing, you can =
move up from single stepping to setting break points before and after =
places you are still scratching you head over.
