for your needs? Just write a simple wrapper (I'll call
it apply$) and use it just like (apply):
; a function to be called on each element of a list

(printout t show: ?x crlf)
)
; (apply$ function expression*)

into recent versions of Jess; it's called map. But I actually don't
think that's what the O.P. is after: rather than calling a function
with each element of a list as successive arguments, I think he wants
to call the function on
I was wondering if there was any way to call a function on a variable
containing a list without having to use a foreach/while loop. (apply + 1 2
3) obviously works, but (apply + (create$ 1 2 3)) doesn't, so that doesn't
help me. This sort of problem comes up a lot, and I usually handle it by
