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. to testy 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
