Makes perfect sense and I got it working. Thanks.
Now I'm trying to bind a variable to something in the data assertion.
I'm trying to bind ?estSalesImpact to the quotient of (say) the
cw-str-cnt-small slot in "data" and the integer 2:
(deftemplate data "the data"
(slot cw-str-cnt-small)
...
)
(bind ?estSalesImpact (/ (data (cw-str-cnt-small)) 2))
This would work in CLOS I think but I can't get the Jess syntax right....
TIA.
