Circles

CIRCLES


by Darrell Smith





If you added up all the time you've spent waiting for your Spectrum to


draw circles you'd probably have enough for a long weekend in Margate


(although watching the circles would be eminently more satisfying).


Darrell Smith has set out to address this problem with his alternative


circle-drawing routine which does the job a whole lot faster. Circles


now just sort of 'appear', which means you can use them for purposes


you'd never previously have bothered with. (Actually I think a similar


program appeared in Pitstop ages ago, but I couldn't find it and


neither, presumably, will you.)





To get it going, type in the Basic (which is mostly a demo and could


therefore be discarded) and save it by doing SAVE "Circles" LINE 1035.


Then, using the Hex Loader, type in the Hex and save it as "CIRCLE


M/C". Reload the whole thing run it and watch the demo.





To draw you own circles...


POKE 56001, x co-ordinate


POKE 56008, y co-ordinate


POKE 56015, radius


and then RANDOMIZE USR 56000.
