I've got some presumably standard-lisp code [from
http://aima.cs.berkeley.edu/lisp/].

 and I want to port it to my [ETH-Oberon] Scheme.
 And I'm not much familiar with lisp/scheme.
 The compile/interpretation shows an error at: #'(
  in the defun: --------
  (defun rename-variables (x)
  "Replace all variables in x with new ones."
  (sublis (mapcar
  snaem '#' yltnerappa ??  (sublis (mapcar #'(lambda (var) 
                     (make-binding var (new-variable var)))
                  (variables-in x))
          x))
------
How would I 're/define'  this  "#'" in my Scheme ?

TIA

== Chris Glur.

In Common Lisp some put a #' before lambda expressions.
In Scheme no such #' is needed.

Therefore change  #'(lambda (var) ...) to (lambda (var) ...).

Keep in mind that Common Lisp and Scheme are two different
languages, so expect things not easily ported.

In Common Lisp it's not needed either.

Yes.

If you haven't found it alreay, the following page
will be useful.
