This is not a syntax that I thought jess would parse correctly. My guess is
that your usage of pattern matching:
?fact <- (sortir ...)
in the middle of a deffunction is *not* going to work. Pattern matching only
happens during a call to (run).
You might try:
;
;first assert your data and call run to allow pattern matching...
;
(deffunction esborraSortir (?numero ?pal)
(assert (sortir (str-cat ?numero "-" ?pal) something))
(run)
)
;
;pattern match for your asserted facts - and do with them what you will...
;
(defrule xyz
?fact <- (sortir ?numero_minus_pal ?)
=>
;do something with ?numero_minus_pal...
(retract ?fact)
)
Again, it is not clear in your original deffunction what you were trying to
do...
