Re: drawing a solid line with sharp 90 degree corners

If you want to try the hard way, I added extended line support to my
simple line drawing demo:

You'll need to study your friend, the Windows API.

Allen,

The simplest way to do this is to use the api function Rectangle. Set
a brush and pen to the desired colors, and the pen width to 1, and
draw rectangles.

Check the demo program "rectangles.f" for more info.

line would have any thickness and be of solid color. The purpose is to
display easily-programmed bar graphs.
