"have" function missing from source code in website

[Brisance]

The following function is missing from the wizards_game.lisp source
file <http://www.landoflisp.com/wizards_game.lisp> in the website.

(defun have (object)
(member object (inventory)))

[Faré]

Better:

(defun have (object)
    (member object (cdr (inventory))))

[Brisance]

I was referring to the canonical version as presented in the book.

Thanks Brisance- I'm updating the source code as we speak.

Thanks Faré- You are right on the "have" command- What you have
pointed out is a bug, though of course very harmless. I will note it
in the errata I'm compiling.
