From: "William K. Cadwallender" (LCWSL) <wkc@ARDC.ARPA> I was at a seminar in applied AI recently, and someone there told me about a LISP written in Aztec C under CP/M (... something like Z-LISP?) which was allegedly in the public domain and available possibly from SIMTEL. Does anyone out there know anything about this LISP, or any LISP that I could run in any manner on a 6502 system? William Cadwallender (wkc@ARDC) P.S. I am interested in the C SOURCE code for this thing.

I got a copy of XLISP from an RCPM in Thousand Oaks Calif. It is
written in C (Got it in a library file with source, and object for an
IBM-PC). To me, XLISP looks kind of like you took a Lisp compiler, and
a C compiler, and placed them in a blender on mix...
It contains old favorites like CAR and CDR, but also includes things
like GETC and PUTC. The phone number for the RCPM is: (805) 492-5472.

Hi,
I downloaded XLISP.COM from simtel20 to my Z80 micro and it works fine.
(This file is Z80 object code.) I then transferred the source files
(yes, they are written in Aztec C) and compiled them on a VAX running
4.2 BSD. I only had to make two minor function changes (a plug for Aztec C).
XLISP is a nice system for learning LISP and object-oriented programming,
but it is NOT LISP. The author says so himself in the manual. It is a
hodge-podge of C and LISP, much to the detriment of the LISP side. For
instance, there is no way (that I have been able to find) to convert strings
into atoms and vice versa.
I would recommend trying XLISP, but with reservations. It is a nice,
Public Domain LISPish language that will help you learn the fundamentals
of LISP, but it cannot compare with a true LISP implementation. (I don't
mean to sound totally negative, and XLISP has some nice extensions that
I wish Franz Lisp had.)
