Common Lisp is an implementation of Lisp.
Other implementations of Lisp.
Common Lisp, commonly abbreviated CL, is a dialect of the Lisp programming language, standardised by ANSI X3.226-1994. Developed as a common successor to Maclisp and Lisp Machine Lisp, it is not an implementation but a language specification. Several implementations of the Common Lisp standard are available, including commercial products and open source software.
Common Lisp is a general-purpose programming language, in contrast to Lisp variants such as Emacs Lisp and AutoLISP which are embedded extension languages in particular products. Unlike many earlier Lisps, Common Lisp (like Scheme) uses lexical variable scope.
The "CL-USER> " prompt seen in front of some examples shows that the code was run in a Lisp read-eval-print loop, or REPL, running interactively in an environment such as SLIME.
