ROTATE by Pedros Davakis Foreign correspondence this month comes courtesy of Mr Davakis of sunny Greece, who sends me this nice little routine which flips a predefined window about its horizontal axis. The effect is instantaneous, so it'll be of more use as a programming aid rather than as a fancy display. There's absolutely no BASIC to worry about, so just use the provided Hex Loader to type in the few lines of Machine Code (the start address is 62350 and the length is 202 bytes) and POKE the following parameters ... o 62346, column of top-left square of window. o 62347, line of top-left square of window. o 62348, length of window in attribute squares. o 62349, height of window in attribute squares. Then type RANDOMIZE USR 62350 to rotate.
