Explanation
LINE [<colour specification>] <X-coordinate>, <Y-coordinate>,
<X-coordinate>, <Y-coordinate> [,<X-coordinate>, <Y-coordinate>] ...
<colour specification> = [<palette code>][,<mode>]
The LINE statement draws line(s) connecting given points in the specified colour.
<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 specification> parameter is identical to that of
the SET statement. If this parameter is omitted, the colour specification made in
the COLOR statement is assumed. If coordinates outside the display area are speci-
fied, the line is clipped off at the boundary of the display area,

The above program draws lines that connect from points (10,20), (260,180), to (380,
60) in the colour previously specified from palette code 2 in superimpose mode 0.
