Dear All

Is the following type of thing possible in Spin?

repeat while diff_x > previous_diff_x
or
repeat while diff_y > previous_diff_y

or maybe

repeat while diff_x > previous_diff_x or diff_y > previous_diff_y

TIA David Young

    Had you typed that code into the Propeller Tool instead of the forums, you could have pressed F8 and found the answer to be "Yes." tongue.gif

    Of course, withing the repeat while structure you need to update the variables being used in the condition so that you can break free of the loop. You may want to add parenthesis to make your intentions absolutely clear:

    repeat while (x > lastx) or (y > lasty)
  ...

    repeat while diff_x > previous_diff_x or diff_y > previous_diff_y

    is perfectly acceptable
