Something like this would do it...

--gordy


function getCirclePoints pXOrigin, pYOrigin, pNumPoints, pRadius
local tIncr, tTheta, tTwoPi, tX, tY, tPoints
put pi * 2 into tTwoPi
put tTwoPi / pNumPoints into tIncr
put 0 into tTheta
repeat pNumPoints times
put pRadius * cos(tTheta) + pXOrigin into tX
put pRadius * sin(tTheta) + pYOrigin into tY
put tX & "," & tY & return after tPoints
add tIncr to tTheta
end repeat
return tPoints
end getCirclePoints
