Hi,
I think is only a typo. I run the program in Protege
and got the following output:-
Jess> (batch test.clp)
<== Activation: MAIN::print-adv-attributes-facts :
f-1
<== Activation: MAIN::print-adv-attributes-facts :
f-0
==> Activation: MAIN::print-adv-attributes-facts :
f-0
==> Activation: MAIN::print-adv-attributes-facts :
f-1
MAIN::print-adv-attributes-facts: +1+1+1+t
TRUE
I tried to put the Jess code into Java, it is not
working, Java is complaining '<-' error on this
symbol.
I think the representation of facts and printout in
Java is different.
I am reading the book Jess In Action, trying to find
how to do it.
