If you have a variable "?f" referring to the fact, and "?c" referring to the current contents of the slot then you'd say (modify ?f (alpha (create$ ?c d e f))) For example in a rule like (defrule modify-slot ?f <- (alphalist (alphalist $?c)) => (modify ?f (alpha (create$ ?c d e f)))) --------------------------------------------------------- Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
