Is Scheme a lisp?
Frequently Asked Questions for comp.lang.lispScheme is a member of the greater family of Lisp languages, assuming that is considered to include others like Dylan and Emacs Lisp. The design of Scheme predates the ANSI Common Lisp standard, and some CL features such as lexical scoping may be considered to have been derived from Scheme. More detailed comparative discussions don't generally prove very productive; those that are interested in discussing Scheme should first consider discussing it in comp.lang.
Related QuestionsCommon Lisp FAQYes. Anyway, the Scheme standard (R5RS) says it is. ("Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language.") On the other hand, Scheme and Common Lisp, while sharing an intellectual legacy and a number of important characteristics, also differ in ways just subtle enough to stir up a good old fashion religious war. Consequently, Scheme vs. Common Lisp discussions almost never go well.Related Questions
What is the difference between Scheme and Common Lisp?
Kantrowitz & Margolin comp.lang.lisp FAQScheme is a dialect of Lisp that stresses conceptual elegance and simplicity. It is specified in R4RS and IEEE standard P1178. (See the Scheme FAQ for details on standards for Scheme.) Scheme is much smaller than Common Lisp; the specification is about 50 pages, compared to Common Lisp's 1300 page draft standard. (See question [4-10] for details on standards for Common Lisp.) Advocates of Scheme often find it amusing that the Scheme standard is shorter than the index to CLtL2.
Related QuestionsWhich should I learn, Common Lisp or Scheme? What's the difference?
Lisp FAQCommon Lisp is powerful but ugly. Scheme is small and clean, but the standard only defines the inner core of the language. If I had to deliver an application I'd probably use Common Lisp; if I were teaching a course I might use Scheme (but with Common Lisp macros).

Lisp FAQLisp is a family of programming languages descended from a language John McCarthy invented (or more accurately, discovered) in the late 1950s. The two main dialects now are Common Lisp and Scheme. We're working on a new dialect called Arc.

Related QuestionsWhy doesn't Common Lisp have continuations?
Frequently Asked Questions for comp.lang.lispContinuations are a great theoretical tool; if a language has first-class, multiply invocable continuations then one can build threads, exceptions, coroutines, and the kitchen sink on top. However, there is an implementation burden with continuations; supporting first-class, multiply invocable continuations complicates things tremendously for the Lisp implementor.
Related QuestionsHow do I call non-Lisp functions from Lisp?
Kantrowitz & Margolin comp.lang.lisp FAQMost Lisp implementations for systems where Lisp is not the most common language provide a "foreign function" interface. As of now there has been no significant standardization effort in this area. They tend to be similar, but there are enough differences that it would be inappropriate to try to describe them all here.

Related QuestionsHow can I learn Lisp?
Lisp FAQThe way to learn any language is to write programs in it. You have two main dialects to choose between: Scheme and Common Lisp. They each have advantages and disadvantages, but the differences between them are tiny compared to the differences between them and other languages, so if you want to start learning Lisp, it doesn't matter which you choose. There are good books about both dialects, and many good free implementations.

Related QuestionsWhere can I get a Lisp interpreter?
Staging Area for the Common Lisp FAQYou probably mean an interactive command processor that accepts Lisp expressions, evaluates them and prints their results. If so, you should simply look for a Common Lisp implementation or development environment, without regard to how expressions are processed. Although native machine code Lisp compilers have been available since the early 1960s, many outsiders still tend to refer to Lisp environments as "interpreters", with an implied assumption of poor performance.
Related QuestionsIs Lisp Slow?
Staging Area for the Common Lisp FAQAnswer 2: Some free Common Lisp implementations have native-code compilers that are about half as fast as C. This translates to 2-4 times the speed of Java and 50-80 times the speed of Perl, Python, or Ruby. Refer to http://www.norvig.com/Lisp-retro.html for details.

You can think of them as scripts, macros, programs, or code. Basically, they are just text files with instructions (in a special language) that AutoCAD uses to automate repetitive or complicated AutoCAD tasks. An.lsp ?

Common Lisp FAQABCL (Armed Bear Common Lisp) is an implementation of ANSI Common Lisp that runs in a Java virtual machine. It provides a runtime system, a compiler that compiles Lisp source to JVM bytecode, and an interactive REPL for program development. It runs on any platform that support Java 1.4 (or later), including Linux, Windows, and Mac OS X. It is, by the author's admission, a relatively young implementation, and has some notable limitations in its CLOS implementation.
