A statement which draws a line on the screen. DRAW is followed by the X and Y coordinates of the end of the line; the optional qualifier BY indicates that the coordinates are relative (offsets from the start of the line) rather than absolute.
The start of the line is either the end of the last line drawn or a point specified by a MOVE statement.
The line is drawn in the current graphics foreground colour. This colour can be changed using the GCOL statement.
