<colour specification> = <palette code>,<superimpose mode>
The BLINE statement changes the colour of line(s) connecting given points on the
screen according to the rule shown below. < X-coordinate> and < Y-coordinate >
are numerical expressions (i.e., numeric constants, variables, or expressions), Their
range of values is the same as that for the SET statement. The <colour specifica-
tion> parameter is identical to that of the RESET statement. If this parameter is
omitted, the colour specification made in the COLOR statement is assumed. If coor-
dinates outside the display area are specified, only the line segment within the dis-
play area is deleted. See Appendix A for more information.

Explanation
Example
BOX [<colour specification>] <X-coordinate 1>, <Y-coordinate 1>,
<X-coordinate 2>, <Y-coordinate 2> [,<palette code>]
<colour specification> = [<palette code>][,<superimpose mode>]
The BOX statement uses two pairs of coordinates as the location of the opposing
corners of the box. <X-coordinate> and < Y-coordinate> are numerical expres-
sions. Their range of values is the same as that for the SET statement.
The <colour specification> parameter is identical to that of the SET statement.
If this parameter is omitted, the colour specification mode in the COLOR state-
ment is assumed.
The last <palette code> parameter specifies that the box must be painted in the
specified colour. When this parameter is omitted, only the borders are drawn.
