Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
In the usual parenthesized syntax of Lisp, an S-expression is classically defined [1] as an atom of the form x, or; an expression of the form (x. y) where x and y are S-expressions. This definition reflects LISP's representation of a list as a series of "cells", each one an ordered pair. In plain lists, y points to the next cell (if any), thus ...

Embeddable Common Lisp (ECL) is a small implementation of the ANSI Common Lisp programming language that can be used stand-alone or embedded in extant applications written in C. It creates OS-native executables and libraries (i.e. Executable and Linkable Format (ELF) files on unix) from Common Lisp code, and runs on most platforms that support ...
Because of Lisp's early heritage in list processing, it has a wide array of higher-order functions relating to iteration over sequences. In many cases where an explicit loop would be needed in other languages (like a for loop in C) in Lisp the same task can be accomplished with a higher-order function. (The same is true of many functional ...
For instance, many Common Lisp programmers like to use descriptive variable names such as list or string which could cause problems in Scheme, as they would locally shadow function names. Whether a separate namespace for functions is an advantage is a source of contention in the Lisp community. It is usually referred to as the Lisp-1 vs. Lisp-2 ...
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
Common Lisp enhanced and standardized, published in ANSI standard document ANSI INCITS 226-1994; to the features of Common Lisp, it adds the loop macro, and the Common Lisp Object System (CLOS) to provide object-oriented programming paradigm with multiple dispatch (multimethods), and method combinations; runs on many platforms: Unix, Linux ...
