Or more simply:
(assert (a "nice string"))
(assert (b nice)) ; note: "nice" (in quotes) won't work
(defrule r1
(a ?x)
(b ?y&:(member$ ?y (explode$ ?x)))
=>
(printout t "Found!" crlf)
)
(run)
i.e. a non-zero value from (member$) evaluates in the pattern above like
a TRUE - or like (neq FALSE ...))

Hi,
I am having trouble in getting to multifields and strings.
I was trying to evaluate the contents of a string in a rule's LHS:
(assert (a "nice string"))
(defrule r1
(a ?x)
?s <- (explode$ ?x)
?s <- (nice ?what)
=>
(printout t ?what crlf)
)
I know I cannot do this. But I cannot figure out how to do something
like this...
Thank you.
Henrique
