Common Lisp Exercises/Problems

Question

I'm working through Practical Common Lisp presently

http://www.gigamonkeys.com/book/

It's an excellent book with some practical assignments towards the end, but I'm looking for basic problems that explore the use of functions, variables and macros. Can anybody suggest a suitable resource to work through in order to reinforce the concepts presented?

Answer 1

Project Euler is a great source of programming problems

also, there is Rosetta Code

Answer 2

You may also want to try the SICP exercises in Common Lisp.

Answer 3

There are great exercises in ANSI Common Lisp the book, http://www.paulgraham.com/acl.html, for each chapter. Great book too, my favorite to learn Lisp with and as a reference.
