This is an experimental feature that may change in future versions.
It is provided for compatibility with the Windows version of BBC BASIC and to enhance the code readibility of the Z80 version.
A statement which draws a circle or disc (filled circle). CIRCLE is followed by the X and Y coordinates of the centre of the circle and the radius. To draw a filled (solid) circle rather than an outline circle, use CIRCLE FILL.
The graphics origin (X=0, Y=0) is normally the bottom-left of the screen. The origin can be changed using the VDU 29 command. See the Graphics section for more details.
The circle or disc is drawn in the current graphics foreground colour. This colour can be changed using the GCOL statement.
CIRCLE x,y,r is equivalent to MOVE x,y : PLOT 145,r,0.
