(1) You must use global variables in the patterns of a rule. These
have funny names - note the two asterisks - and are defined like this:
(defglobal ?*n* = 1)
(2) A pattern that tests for the equalitiy of a slot's value to some
expression is written like this:
(defrule myrule
(mitsos (x = (+ ?*n* 1)))
=>
...
(3) A few line ends at all the right places make for better reading
of a mail, don't you think so ;-)
