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.
