You can handle the "run continuously" part using the "slot-specific"
declaration in the "trial" deftemplate; see http://www.jessrules.com/
jess/docs/70/rules.html#slot-specific .
As far as the single value, that's because each modify call sets the
slot to contain a single item, the sum of ?x and ?b. If you want to
accumulate a set of values in a slot, you need to save all the values
in a list, and then call modify once, at the end.

For starters I am trying to add multislot values to a 2nd single
slot value
and store the outcome in a third multislot. Eventually i will be
trying to
add two multislot fields together, with all possible combination

stored in a third multislot.
The following example runs but doesnt complete (it runs
continuously). If i
run a step (run 1) then i only get one value, the last one
evaluated, saved
to multislot c.
(deftemplate trial
(multislot a)
(slot b)
(multislot c))
(deffunction trial1 (?a ?b)
(foreach ?x ?a
(bind $?y(+ ?x ?b))
(printout t ?y crlf)
(modify 1 (c $?y))))
(defrule PTF
(trial (a $?x) (b ?b))
=>
(trial1 ?x ?b))
(reset)
(assert (soil (a 1 2 3) (b 5)))
