SCREEN SAVER by Richard Swann Back (back! Back!) in full effect, Dicky's second contribution of the month is none other than a screen saver utility as found on, quoth Dicky, "posh computers". Just an interjection of mild interest at this point - the equivalent of both Richard's programs this month can be found already built into the ROM of that "posh computer", the SAM Coupe, and it's good to see Dicky acknowledging the SAM's superiority at last! For those not in the know, such a prog is used to blank the screen out after 'n' minutes, so as to save the TV's phosphor from sustaining a permanent scar due to displaying a static image for too long. To actually use the thing, you first need to work out after how many frames you want the screen to blank out. The value can be anything up to 65535, which works out at about twenty-two minutes, and just to give you a rough working guide, one frame lasts one fiftieth of a second. Using n as the number of frames, POKE 64847, n-INT(n/256)*256: POKE 64848,INT(n/256): RANDOMIZE USR 64768 and you're away. Two words of warning, though - firstly, don't use interrupts, and secondly, leave all RAM above 64768 free for the routine to use.
