1. The color source indirectly selects the color for the drawing. There are five
color sources, but color source 4 (the border color) cannot be used in drawing
commands. Color sources 2 and 3 can be used only in multicolor modes.
0 screen background color
1 foreground color
2 multicolor mode extra color 1
3 multicolor mode extra color 2
The color-source number you include in the DRAW command tells the com
puter to draw in the current color for that source. For example, if you select 1, the
computer draws the shape in the current foreground color. If you want to use a
color other than one of the current source values, you must first use the COLOR
command to change one of the source values. Only sources 1 and 2 can be used to
draw with more than one color on the same screen. Sources 0 and 3 are global
(whole screen) colors.
If you want to use the default value (1, the current foreground color), you do
not have to type a number, but you must type a comma before the next parameter.
2. The first coordinates name the starting point of the drawing. If you omit this
parameter, the current location of the pixel cursor is used as the starting point. If
you omit the first coordinates, no placeholder comma is required.
3. TO is a required part of the DRAW command unless you are just drawing a
dot.
4. The second and subsequent coordinates name the ending points of the line
segments. You can add more than one TO clause to draw complex designs. If you
