Thank you for your reply.
I'm using CLISP on Windows 7, and simply wanted to format the entries in REPL by using tabs to indent. Of course, I got something different from what I expected. This is a tutoring project, so I'm trying to make it as easy as possible.
I may just move to Racket, or I may actually implement emacs on Windows, but I'm just trying to eliminate admin overhead.
As for output; I think I'll just direct my student to Project Euler and see what that does.
But, OK, suppose you want to create a list of skills to master in LISP, such as the ones on this site: http://www.philipreames.com/Blog/things ... m-to-know/
Examples and practice are the keys to mastering any skill, and I was looking for example sites. I have:http://www.codechef.com/problems/easy
and resources for books. I was hoping there was a cool site especially for LISP.
