Here's what I see about the LINE command from my book "Going Ahead with Extended Color Basic":

LINE (x1,y1)-(x2,y2),a,b

(x1,y1) specifies the line's start point.  x1 is any numeric expression from 0 to 255, y1 from 0 to 191.

(x2, y2) specifies the line's end point.  x1 is any numeric expression from 0 to 255, y1 from 0 to 191.

a is eitehr PSET or PRESET

b is either B or BF.  This is optional.

Note: If start point is not specified, the Computer will start at teh most recent end point in the program.  If there isn't a previous end point in the program, (128,96) will be used as the start point.

I don't see a reference to a color parameter in the PRESET command.  Let me know if you need me to look up anything else; I'm more than happy to help out.
