Hi everybody, I've got the Lispworks 4.1.20 for windows and I'm trying to do the following in the knowledgeworks listener ==> (kw:defrule m-m :backward ((m-m) <-- (fail))) and I get the following error: Error: Expected <-- but found <-- 1 (abort) Return to level 0. 2 Return to top loop level 0. Type :b for backtrace, .....etc Any idea of what's wrong? thanks. Miro

Ahem. That shouldn't that be:
(in-package "KW-USER")
Or as Tim suggests if you have defined an application package then it
should use "KW".

Someone used ~A when they should have used ~S in the error message! My guess is you want a (use-package :kw) to make '<-- be the same as kw:<--. --tim
