First of all, just to tell you that what your code will end up doing is displaying a wagon wheel with a bunch of spokes instead of an actual circle(not sure if you want that). You may want to try to use the STEP command with the FOR NEXT loop so you can get a more precise shape. I still dont see how you came up with your angle*pi/180 but if that is correct then are gonna end up with the display that I just discribed, based on what the LINE command does, which is not exactly a circle...reply with a little note on your progress.

change "angle*pai#/180.0" to just "angle" because darkbasic measures angles in degrees, not radians.

you are right Shadow Spirit,

COS()
This command will return the cosine of value were the value is in degrees between 0 and 360. The value can be a real or integer number. The return value should be a real number.

i should read html manual carefully.
thanks!
