If you think of questions that are appropriate for this FAQ, or would like to improve an answer, please send email to us at email@example.com. Note that the lisp-faq mailing list is for discussion of the content of the FAQ posting only. It is not the place to ask questions about Scheme; use either the firstname.lastname@example.org mailing list, the comp.lang.scheme newsgroup or the Scheme Digest (email@example.com) for that. If a question appears frequently in one of those forums, it will get added to the FAQ list. *** Copyright: Copyright (c) 1993-94 by Mark Kantrowitz and Barry Margolin. All rights reserved.

This file/article is an attempt to gather these questions and their answers into a convenient reference for Scheme programmers. It (or a reference to it) is posted periodically. The hope is that this will cut down on the user time and network bandwidth used to post, read and respond to the same questions over and over, as well as providing education by answering questions some readers may not even have thought to ask. This is not a Scheme tutorial, nor is it an exhaustive list of all Scheme intricacies. Scheme is a very powerful and expressive language, but with that power comes many complexities. This list attempts to address the ones that average Scheme programmers are likely to encounter. If you are new to Scheme, see the answer to the question "How can I learn Scheme?" [1-3]. The latest version of this file is available via anonymous FTP from CMU: To obtain the files from CMU, connect by anonymous FTP to ftp.cs.cmu.edu:/user/ai/pubs/faqs/scheme/ [126.96.36.199] using username "anonymous" and password "name@host" (substitute your email address) or via AFS in the Andrew File System directory /afs/cs.cmu.edu/project/ai-repository/ai/pubs/faqs/scheme/ and get the files scheme_1.faq and scheme_2.faq. You can also obtain a copy of the FAQ by sending a message to firstname.lastname@example.org with Send Scheme FAQ in the message body. An automatically generated HTML version of the Scheme FAQ is accessible by WWW as part of the AI-related FAQs Mosaic page. The URL for this resource is http://www.cs.cmu.edu/Web/Groups/AI/html/faqs/top.html The direct URL for the Lisp FAQ is http://www.cs.cmu.edu/Web/Groups/AI/html/faqs/lang/scheme/top.html We've tried to minimize the overlap with the FAQ postings to the comp.lang.lisp, comp.lang.clos and comp.ai newsgroups, so if you don't find what you're looking for here, we suggest you try the FAQs for those newsgroups. These FAQs should be available by anonymous ftp from rtfm.mit.edu:/pub/usenet/news.answers/ [188.8.131.52] in the lisp-faq/, ai-faq/ and scheme-faq/ subdirectories or by email. For instructions on email retrieval, send a mail message to email@example.com with "help" and "index" on separate lines in the body of the message.
