Well, the code is "working" in the sense that it more or
less does what code like that is suppose to do: illustrate
a technique. You don't see the largest line, since it is
being drawn in the same color as the background color. :-(

What I would do is set up a 3D transformation, using something
like SCALE3D. Then use MAP_SET with the /T3D keyword set
to draw your map in the XY plane. Then just use the PLOTS
portion of this code (with better colors) to draw your
height lines.

Should work great. :-)

Cheers,

David
