See the posted reply I did just a couple days ago Titled
"Problems with DOT" The reason FD 0 works in UCBLogo
is the same reason a Square does not come out square with
a reverse pen (i.e. it draws the 4 corner twice). The
reason FD 0 does not work in MSWLogo is the same reason
a Square comes out Square in reverse pen (i.e. it draws
the 4 corners once).
You can compensate for it though:
to reversesquare :size
penreverse
repeat 4 [pu fd 1 pd fd :size-1 rt 90]
end
The above assumes a penwidth of 1.
SideBar:
Geometry is "analog" (continuous), the screen (pixels) is "digital"
or discrete. It's basically a Analog to Digital conversion
(Rasterization) artifact. And if you apply a common rule used in
electronics, you need greater than twice the sampling rate to not
loose any information. That is, Logo should really should use multiple
pixels as the lowest resolution, so it has more room to maneuver.
