I was a newbie to lush programming. And I can't make it work properly

I am using Fedora 12/Linux as platform. My lush version is
lush-1.2.1-6.

When I trying,

###############################################
(de harmonic (n)
((-double-) n)
(let* ((z 0) (i 0))
((-double-) z i)
(while (< i n) (incr i) (incr z (/ i)))))
= harmonic
(dhc-make "junk" harmonic)

##################################################

I have search the Internet, I get a bug report.
http://lists.ibiblio.org/pipermail/sm-grimoire-bugs/2006-May/004254.html

It was reported long time ago. I wonder if there is a way to fix it.
Thanks a lot~

I can't help you with LUSH. I considered using it when I started
programming in Lisp, and decided that it is an antiquated and badly
designed Lisp dialect.

Unless you have a compelling reason to use Lush, I would recommend
that you use Common Lisp instead. It will give you a much more
advanced programming language with implementations that are actively
developed. You will go much, much further with CL.

A good introductory book to Common Lisp is Peter Seibels Practical
Common Lisp, available online at http://www.gigamonkeys.com/book/ .

By the way, this is how your function could look like in CL:

(defun harmonic (n)
(loop
for i from 1 to n
summing (/ i)))

Hope this helps,

Tamas

Oh, thank you. I really appreciate your help.
I am just looking around and finding LUSH can be used with a lot of
tools, and it can create 2D&3D things which is interesting. But it's
really buggy. It seems that I made a really bad choice. I will come
back to CL. Thank you~
