JOHNCOLLETT  A earlier reviewer of ACSLogo condemned it, saying it “Wouldn’t work for me”. I suspect that he overlooked the need to _select_ a part of the script window before hitting Cmd/Return. No command selected, no command carried out. I can report that ASCLogo works perfectly for me. I have had hours of addictive fun with it, with all the old Logo favourites dancing on the screen. The language contains no “while” or “for” procedures, but as the author explains, you can so easily “roll your own”, which I have done, and they work. I looked briefly at some other modern Logo implementations. ACSLogo is the one I am staying with. (10/13/2007, Version: 1.4d)
