If i'm not mistaken the result would be something like this:
it will show a message box with c=310, 311, 312, 313, 314 and then it will end the loop.
Is that correct firedraco?
I've never used the Convert or Messagebox, but your logic is definitely correct.
Since I've never used the convert I can't be sure, but wouldn't it only print the last value of the variable (314) since that's when the conversion was done?
