You could just call (set-reset-globals FALSE), set your global(s) to
the value(s) you want, then call (reset) to evaluate the rules.

Dear Ernest,
I know that when the working memory is changed the rule will be
reevaluated.
You see when I said that with the following simple function my
problem disappeared I didn’t realize that in this example I
initialize the global variable calling that function and because of
that my application works.
(deffunction read-number()
(printout t "Read the number")
(bind ?n (read))
(return ?n))
(defglobal ?*category* = (read-number))
It is possible to initialize a global variable using a value from a
text field?
If the answer is yes how can I define that function?
I tried to put the defglobal construct in the following function but
a constructor can’t stay there:
(deffunction read-category(?EVENT)
(defglobal ?*category*=(integer(?*textfield* getText)))
(assert(insert(integer(?*textfield* getText)))))
If I define the global variable outside this function and bind it
after with the new value, still wont works because the rule won’t be
reevaluated.
What shall I do?
Best regards,
Ana
