How do I draw a circle using scripts?

Easiest way is
when flag clicked
go to x: (0) y: (100)
point in direction [90 v]
clear
pen down
repeat (360)
move (1) steps
turn cw (1) degrees
end
pen up

define draw circle with radius (r) at x: (x) y: (y)
set [i v] to [0]
pen up
go to x: (x) y: ((y)+(r))
pen down
repeat (360)
go to x: ((x)+((r)*([sin v] of (i)))) y: ((y)+((r)*([cos v] of (i))))
change [i v] by (1)

And if he wants an ellipse he should use:

define draw ellipse with radii (r1),(r2) at x: (x) y: (y)
set [i v] to [0]
pen up
go to x: (x) y: ((y)+(r))
pen down
repeat (360)
go to x: ((x)+((r1)*([sin v] of (i)))) y: ((y)+((r2)*([cos v] of (i))))
change [i v] by (1)
