From: Daniel.Zigmond@SPICE.CS.CMU.EDU A guy from Commodore is sending me a copy of Cambridge Lisp 68000 for the Amiga. With luck, it will get here about the same time my developer's package does (some time next week). As of now I know nothing about this system but if anyone has any questions, I will do my best to answer them when the hardware and softawre arrive. Dan (djz@cmu-cs-spice)

I've been doing some stuff with Lisp lately and I thought the the following
might be interesting. The amiga's Lisp will compute 2**100000 in 12.7
hours of cpu time, (according to the built in Lisp timing functions).
I used a compiled version of the following code, which I am posting because
some people do not have documentation and this might be useful to them.
The answer is about 7 pages of 60 columns. I plan on checking it with
a Symbolics when I get a chance.
(global 'high)
(setq high 100000)
(global '(outfile)) ;;; doesn't seem to matter.
(global '(screen))
(global '(cl1))
(global '(cl2))
(de temp ( i x)
(cond ((lessp i high) (temp (add1 i) (times2 x 2)))
(t
(setq screen (wrs outfile))
(print i)
(print x)
(print (difference (time) cl1))
(print (difference (gctime) cl2))
(wrs screen)
(close outfile)
} ;;; super paren
(compile '(temp))
(excise) ;;; get rid of uneeded stuff in environment
(reclaim) ;;; (gc)
(setq cl1 (time))
(setq cl2 (gctime))
(rds nil)
;;; The compiler seems to be intelligent enough to sense tail recursion
;;; This file is meant to be loaded
;;; If people want more info. send mail to me.
;;; If I get enough mail I will post answers, but I hate to tie up the net.

****** Does anyone know if Metamaco's Lisp for the Amiga is out? If so is it a decent implementation ? Hooks into the operating system ? Thanks, Charles Ditzel ...uw-beaver!ssc-vax!ditzel
