LINE                     Draw Line or Box

 LINE [[STEP] (x1,y1)] - [STEP] (x2,y2) [,[color] [,B[F]] [,style]]

    Draws a line or a box at specified coordinates, in a specified color.

        STEP    If included, coordinates are relative to last graphics
                point referenced (LPR). If omitted, coordinates are
                absolute.

       x1,y1    If ,B option is used, x1,y1 and x2,y2 are corner
       x2,y2    coordinates (column, row) of a rectangular box; otherwise
                x1,y1 and x2,y2 are end points of a line. The coordinates
                are in pixel points.

       color    Specifies color to use. Defaults to 3 in medium
                resolution, 1 in high resolution.

           B    Tells Turbo Basic to draw a rectangular box instead of a
                line.

           F    Tells Turbo Basic to fill the box.

       style    Allows you to draw a broken (dashed) line or box (see
                below).

   -------------------------------------------------------------------------

      Notes:    If the point (x1,y1) is not specified, drawing is started
                from the last point referenced (LPR).

                If STEP is included with x2,y2 but not x1,y1, x2 and y2
                are measured relative to the absolute coordinate pair
                (x1,y1).

                Turbo Basic treats style as a 16-bit integer mask,
                plotting the 1 bits and skipping the 0 bits, and repeating
                the pattern as many times as necessary to create the
                specified line. Thus a style value of 43690 (AAAAh,
                1010101010101010b) would produce an evenly dotted line or
                box, with every other pixel plotted. Note that Turbo Basic
                ignores the "off" pixels; it does not plot them in the
                background color.

                The style parameter has no affect on filled boxes.

                The last point referenced (LPR) after the LINE statement
                is the second point specified in the statement.
