I have a project in clips (fuzzy) and I would like to ask you something.
I use a template (A and B are defined with low, normal, high):
(slot FA (type FUZZY-VALUE A))
(slot FB (type FUZZY-VALUE B))
then I initialise the variables
(FA (pi 0 ?*a*))
(FB (pi 0 ?*b*))
And I am writing a rule
(declare (salience 430))
(fuz (FA ?c))
(printout t "" ?c "")
But the output is '???'
How can I print low, high, normal ?
And last question can I pause the program with a command ?
