There are many ways. One easy one is to use the 'store' and 'fetch'
functions.
(defrule find-os
?ask-stmt <- (ask-os ?hostname)
(has-os ?hostname ?osname)
=>
(retract ?ask-stmt)
(store OSNAME ?osname)
(assert (host-os myhost unix))
Rete rete = ...
rete.executeCommand("(assert (ask-os myhost))");
rete.run();
String osname = rete.fetch("OSNAME").stringValue();
See the README for details.
