ACSLogo

Just an FYI, but ACSLogo is now Intel-only (1.5.0 was the last PPC/Universal version).

All I had to say to this Logo is: ... simply the best of all... As a teacher of informatics I really can compare this language and this ACSLogo to other dialects and attempts to realize it on a computer.This version is totally stable, clear and supplies the user with an excellent resulting grafics. On an iMac from 2009 I use it now since times of a PPC and one of the first logos on the market. And I never have had big problems with it. With these new iMacs it is a very fast interpreter language and it is very easy to learn and demonstrate the main features of logo. Therefore I thank the developers for this great programming language.

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)

Doesn't work for me. iMac G4 1.2Ghz plus OSX 10.3.8. When I press command+enter after typing a valid logo instruction nothing happens, except the the word "Special" in the menu bar flashes.... Doh!
