SchemeLanguage

Scheme is a ComputerLanguage?.

: Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy Lewis Steele Jr. and Gerald Jay Sussman. It was designed to have an exceptionally clear and simple semantics and few different ways to form expressions. A wide variety of programming paradigms, including imperative, functional, and message passing styles, find convenient expression in Scheme.

: Scheme was one of the first programming languages to incorporate first class procedures as in the lambda calculus, thereby proving the usefulness of static scope rules and block structure in a dynamically typed language. Scheme was the first major dialect of Lisp to distinguish procedures from lambda expressions and symbols, to use a single lexical environment for all variables, and to evaluate the operator position of a procedure call in the same way as an operand position. By relying entirely on procedure calls to express iteration, Scheme emphasized the fact that tail-recursive procedure calls are essentially goto's that pass arguments. Scheme was the first widely used programming language to embrace first class escape procedures, from which all previously known sequential control structures can be synthesized. More recently, building upon the design of generic arithmetic in Common Lisp, Scheme introduced the concept of exact and inexact numbers.

: Scheme recently became the first programming language to support hygienic macros, which permit the syntax of a block-structured language to be extended reliably.

There are many Scheme [implementations] for a variety of OperatingSystems and architectures.

There are two standards for Scheme:

IEEE standard 1178-1990.
R5RS standard (Revised^5 Report on the algorithmic language Scheme) which is the latest of the RnRS standards (http://www.schemers.org/Documents/Standards/R5RS/HTML/)
