XLISP: XLISP programming language
XLISP 2.0 is an experimental programming language written by David Betz
combining some of the features of LISP with an object-oriented
extension capability. Tom Almy extended XLISP to bring it into closer
conformance with Common Lisp (version 2.1g*).
Version 2.1g* was received direct from Tom Almy.
ufg.arc Universal game playing functions for XLISP
xmath.arc X-Lisp math functions to accompany X-Lisp
Version 2.0 is available by anonymous ftp from
cs.orst.edu:/pub/xlisp/ [188.8.131.52] or
Version 2.1 is the same as XLISP 2.0, but modified to
bring it closer to Common Lisp and with several bugs
fixed. It can be obtained by anonymous ftp from
as the files xlisp21e.zip and xlisp21e.tar.Z. The xlisp21e.zip
file comes with IBM/PC executables.
A Macintosh port of version 2.1e (and the C source code
to its interface) is also available, from Macintosh
ftp sites such as
A version of XLISP-PLUS 2.1g that includes an experimental
byte code compiler is available by anonymous ftp from
as the file xlisp21gbc.tar.gz. Write to Luke Tierney
for more information.
