2.7.6.9 CIRCLE
I Format I
Function
Example
(abbreviated format:
Cl.)
CIRCLE x, y, r, s, e, d
x, y . . .. .. . Location of the center (-999 to 999)
r
....... . .. Radius (0 to 999)
s .. . ...... . Starting angle (in degree)
e
.. . . . . ... . Ending angle (in degree)
d .
.. .... ... Step angle (in degree)
This
statement draws a circle or arc with a radius of r and a step of d at location
(x, y), starting
at angle S and ending at angle e. A complete circle is drawn when
s
= 0, e = 360 and d = 0.2.
Actually this statement draws a polygon; therefore, d must be as small as possible in
order
to draw a smooth figure.
s
must be smaller than e. When d = 0, lines connecting the center and the starting
point and the center and the ending point are drawn.
