Well, as primary author of Logo for the Commodore 64, I'm pleased to see
people like it.  I hear Commodore has raised the price of all its
software, so it's probably not $40 anymore.

Not having anything around at the moment to run Logo on, I followed the
alleged bug-generating procedure by hand.  Adding the line highlighted
below in uppercase should get the desired behavior.  If you use entirely
local commands like LT/RT/FD/BK instead of SETXY, you can get a design
which can
be replicated at any angle or position on the screen.

Anyway, it's not a bug in the Logo.  It is unfortunate, however, that
Commodore is giving people the runaround.

   make "y 0
   rt 90
   pu
   repeat 50 [
      setxy 0 :y pd
      fd 40
      make "y :y + 1
      pu
      setxy 0 :y pd
      fd -40
      MAKE "Y :Y + 1
   ]
end
