eXperimental LISP
Synonyms
xlisp
(xlisp) An experimental programming language combining a subset of Common Lisp with an object-oriented extension capability (Class and Object types). It was implemented by David Micheal Betz at Apple to allow experimentation with object-oriented programming on small computers. The C source code has been ported to Unix, Microsoft Windows, Macintosh, Amiga, Atari, and MS-DOS.
Version 2.1 of the interpreter, by Tom Almy is closer to Common Lisp.
