circle (x,y), radius, color, , , ratio (height/width) - the commas are important
example: circle (300,300),100, 14, , , 2/5 'width flat yellow ellipse
circle (500,400),60, 6, , , 3/2 'tall thin brown ellipse
Arc use the circle, radians and a ratio
circle (x,y),radius, color, start angle, end angle, ratio (height/width)
example: circle (50,50),200,5,0,3.14,1/2 ' top half of magenta circle
circle (150,150),100,3,3.14,6.26,1/2 ' bottom half of cyan circle
LINE (x1,y1)-(x2,y2),color 'points at either end of a line
Example: LINE (20,20)-(50,50), 10 ' a light green line between 2 points
Box uses the line tool
LINE (50,50)-(200,200), 11, B 'B creates a light cyan empty box from the line coordinates
LINE (100,100)-(300,300),12,BF ' BF creates a light red FILLED box no edge color
