* Atomic strings: A string is no longer an array of characters ( as in Integer BASIC and C ); it is instead a garbage-collected object ( as in Scheme and Java ).

Common Lisp is most frequently compared with, and contrasted to, Scheme — if only because they are the two most popular Lisp dialects.

Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables.

There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces.

In Scheme, it is ( broadly ) necessary to avoid giving variables names which clash with functions ; Scheme functions frequently have arguments named,, or so as not to conflict with the system function.

In CL, any non-NIL value is treated as true by conditionals, such as, whereas in Scheme all non -# f values are treated as true.

These conventions allow some operators in both languages to serve both as predicates ( answering a boolean-valued question ) and as returning a useful value for further computation, but in Scheme the value '() which is equivalent to NIL in Common Lisp evaluates to true in a boolean expression.

GnuCash is written primarily in C, with a small fraction in Scheme.

ICAO is currently opposed to the inclusion of aviation in the European Union Emission Trading Scheme ( EU ETS ).

The Knights of the Lambda Calculus is a semi-fictional organization of expert LISP and Scheme hackers.

Mutual recursion is very common in the functional programming style, and is often used for programs written in LISP, Scheme, ML, and similar languages.

While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language ( e. g., as in the C language ), or a formal semantics ( e. g., as in Standard ML and Scheme specifications ).

In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby.

The Semester Abroad Scheme is a highly competitive programme open to academically outstanding juniors who wish to follow a regular Cambridge degree course as fully matriculated members of the University.

Scheme is a functional programming language and one of the two main dialects of the programming language Lisp.

The Scheme language is standardized in the official IEEE standard, and a de facto standard called the Revised < sup > n </ sup > Report on the Algorithmic Language Scheme ( RnRS ).

Currently, " Schemer " is commonly used to refer to a Scheme programmer.

There is a portable reference implementation of the proposed implicitly phased libraries for R6RS, called psyntax, which loads and bootstraps itself properly on various older Scheme implementations.

The source code is now specified in Unicode, and a large subset of Unicode characters may now appear in Scheme symbols and identifiers, and there are other minor changes to the lexical rules.

Scheme is a very simple language, much easier to implement than any other language of comparable expressive power.

Even nominally " RAAF " squadrons formed under the Scheme were rarely composed primarily of Australians, and Williams ' efforts to establish a distinct RAAF Group within Bomber Command, similar to the Royal Canadian Air Force's No. 6 Group, did not come to fruition.

The Mother and Child Scheme was a healthcare programme in Ireland that would later become remembered as a major political crisis involving primarily the Irish Government and Roman Catholic Church in the early 1950s.

The National Service Scheme primarily stands for channelizing the student youth for building the nation.

However, prominent functional programming languages such as Common Lisp, Scheme, ISLISP, Clojure, Racket, Erlang, OCaml, Haskell, Scala and F # have been used in industrial and commercial applications by a wide variety of organizations.

Also in the 1970s, the development of Scheme ( a partly functional dialect of Lisp ), as described in the influential Lambda Papers and the 1985 textbook Structure and Interpretation of Computer Programs, brought awareness of the power of functional programming to the wider programming-languages community.

Some functional languages ( e. g., Scheme and Erlang ) mandate that tail calls be optimized by a conforming implementation, due to their prevalence in these languages.

While the languages, by themselves, are simple dynamically typed functional cores, the standard distributions of Scheme or Common Lisp permit imperative or object-oriented programming, as well as static typing.

Some languages are designed to support one particular paradigm ( Smalltalk supports object-oriented programming, Haskell supports functional programming ), while other programming languages support multiple paradigms ( such as Object Pascal, C ++, Java, C #, Visual Basic, Common Lisp, Scheme, Perl, Python, Ruby, Oz and F #).

In functional language compilers, such as those for Scheme, ML and Haskell, continuation-passing style ( CPS ) is generally used while one might expect to find SSA in a compiler for Fortran or C. SSA is formally equivalent to a well-behaved subset of CPS ( excluding non-local control flow, which does not occur when CPS is used as intermediate representation ), so optimizations and transformations formulated in terms of one immediately apply to the other.

A functional ( e. g. Scheme ) programmer would create functions representing both elements and behaviors of the airport.

: operator is similar to the way conditional expressions ( if-then-else constructs ) work in functional programming languages, like Scheme, ML, and Haskell, since if-then-else forms an expression instead of a statement in those languages.

Most of the languages emphasizing functional programming don't need such an operator as their regular conditional expression ( s ) is an expression in the first place e. g. the Scheme expression is equivalent in semantics to the C expression.

MultiLisp is a functional programming language and dialect of the Lisp dialect Scheme, extended with constructs for parallel execution and shared memory ; MultiLisp is implemented in Interlisp.

In functional programming, the function call-with-current-continuation, commonly abbreviated call / cc, is a control operator that originated in its current form in the Scheme programming language and now exists in several other programming languages.

Programming is introduced through Scheme and functional programming throughout the first semester, in parallel with the computer architecture course ( which uses MIPS assembly ).

* Scheme ( programming language )

The Lisp dialect used in Emacs differs substantially from the more modern Common Lisp and Scheme dialects commonly used for applications programming.

* Lazy programming and lazy evaluation in Scheme

* Scheme ( programming language ), a minimalist, multi-paradigm dialect of Lisp

In August 2009, the Scheme Steering Committee which oversees the standardization process announced its intention to recommend splitting Scheme into two languages: a large modern programming language for programmers, and a subset of the large version retaining the minimalism praised by educators and casual implementors ; two working groups were created to work on these two new versions of Scheme.

This subsection describes those features of Scheme that have distinguished it from other programming languages from its earliest days.

These are the aspects of Scheme that most strongly influence any product of the Scheme language, and they are the aspects that all versions of the Scheme programming language, from 1973 onward, share.

Like most modern programming languages and unlike earlier Lisps such as Maclisp or Emacs Lisp, Scheme is lexically scoped: all possible variable bindings in a program unit can be analyzed by reading the text of the program unit without consideration of the contexts in which it may be called.

* A Tour of Scheme in Gambit, introduction on how to do software development in Gambit Scheme for people with experiences in general programming languages.

simple: Scheme ( programming language )

Later programming languages, such as ML and Scheme, extended the term to refer to syntax within a language which could be defined in terms of a language core of essential constructs ; the convenient, higher-level features could be " desugared " and decomposed into that subset.

is also a special form in the Scheme programming language.
