It sounds like you're beginning to learn Racket, which is cool. You may find the the Quick Start documentation at: http://docs.racket-lang.org/quick/index.html a useful way to get started with Racket. At the very least, the quick start will show off some of Racket's capabilities. The Guide at: http://docs.racket-lang.org/guide/index.html can be helpful, but it assumes that you already have some knowledge in general programming. What kind of background do you already have? Are you trying to learn Racket specifically, or general programming? If you're just trying to learn general programming, a systematic textbook, like How to Design Programs book, may help you: http://htdp.org/ _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
