  2. Lisp (programming language) - Wikipedia

    en.wikipedia.org/wiki/Lisp_(programming_language)

    Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. [3] Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran.

  3. Polish notation - Wikipedia

    en.wikipedia.org/wiki/Polish_notation

    Polish notation (PN), also known as normal Polish notation (NPN), [1] Łukasiewicz notation, Warsaw notation, Polish prefix notation or simply prefix notation, is a mathematical notation in which operators precede their operands, in contrast to the more common infix notation, in which operators are placed between operands, as well as reverse Polish notation (RPN), in which operators follow ...

  4. CGOL - Wikipedia

    en.wikipedia.org/wiki/CGOL

    CGOL [1] [2] (pronounced "see goll") is an alternative syntax featuring an extensible algebraic notation for the Lisp programming language.It was designed for MACLISP by Vaughan Pratt and subsequently ported to Common Lisp.

  5. Lisp (book) - Wikipedia

    en.wikipedia.org/wiki/Lisp_(book)

    LISP is a university textbook on the Lisp programming language, written by Patrick Henry Winston and Berthold Klaus Paul Horn. It was first published in 1981, and the third edition of the book was released in 1989. [1] The book is intended to introduce the Lisp programming language and its applications. [2]: Preface

  6. CAR and CDR - Wikipedia

    en.wikipedia.org/wiki/CAR_and_CDR

    In computer programming, CAR (car) / k ɑːr / ⓘ and CDR (cdr) (/ ˈ k ʌ d ər / ⓘ or / ˈ k ʊ d ər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...

  7. cons - Wikipedia

    en.wikipedia.org/wiki/Cons

    In computer programming, cons (/ ˈ k ɒ n z / or / ˈ k ɒ n s /) is a fundamental function in most dialects of the Lisp programming language. cons constructs memory objects which hold two values or pointers to two values. These objects are referred to as (cons) cells, conses, non-atomic s-expressions ("NATSes"), or (cons) pairs.

  8. Reverse Polish notation - Wikipedia

    en.wikipedia.org/wiki/Reverse_Polish_notation

    Video: Keys pressed for calculating eight times six on a HP-32SII (employing RPN) from 1991. Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands.

  9. S-expression - Wikipedia

    en.wikipedia.org/wiki/S-expression

    Lisp programs are valid S-expressions, but not all S-expressions are valid Lisp programs. (1.0 + 3.1) is a valid S-expression, but not a valid Lisp program, since Lisp uses prefix notation and a floating point number (here 1.0) is not valid as an operation (the first element of the expression).
