Right, and in this case, SIN is incremented in very tiny steps t = 0.25 A = 10.0098 t = 0.5 a = 10.0392 t = 0.75 a = 10.0883 t = 1.0 a = 10.1570 t = 1.25 a = 10.2454 t = 1.50 a = 10.3533 t = 1.75 a = 10.4809 t = 2.00 a = 10.6281 t = 3.00 a = 11.4130 t = 5.00 a = 13.9220 Im just not sure how to imple...

I dont really want to sort data, but if you think it will help my graphics skills then might as well, I guess it wont hurt to learn how to sort stuff, may come in hand...

Mike, how do i use this minigrafik program?? And yea, even i know the vic can be bitmapped as explained in the programmers refrence manual, however it is very unpractical on the unexpanded vic because putting the whole screen into hi-resolution mode is very memory intensive, but you can bitmap small...
