As far as I can tell Racket is somehow a super set of Scheme. I think when learning Racket it is easy to go back to some Scheme then if you like. Even Racket could be used as Scheme when you specify it as a language. In a .rkt file you would start this way: #lang r6rs In DrRacket you could choose r6rs as a language. > What % of the book deals with non-Scheme issues? In the GUI version Not quite sure what you mean when saying 'non-Scheme issues'? The GUI is just a library written in Scheme. Would be the same if you would use Cobol in Windows and using a GUI library in Cobol. > of Guess My Number many of the functions/procedures have an argument > of w, which I understand to be world.

I'm not the expert so others may be able to give better answers. -- Manfred ____________________ Racket Users list: http://lists.racket-lang.org/users
