Color
You can set the ON/OFF (white/black) color of a figure's
border and radius lines (see start/end) by specifying a
numeric value of 1 or ~.
If you omit color, BASICG uses 1 (ON/white).
Border
Figure 6. Border of Circle
start/end
Startpoint/Endpoint of Circle
The range for start and end is ~ to 6.283185 (2 x PI).
If you do not enter start and end, the default values of
~ and 6.28 respectively, are used.
A negative start or end value will cause the respective
radius to be drawn in-addition to the arc (i.e., it will
draw a "piece of the pie"). The actual start and endpoints
are determined by taking the absolute value of the specified
start and endpoints. These values are measured in radians.
Note: Radius will not be drawn if start or end is -~.
To draw a radius with start or end as ~, you must use
-~.~~~ •.• ~l.
