I could have sworn that zip was included in list.ss, but apparently not. Certainly, it seems a natural. Anyway, a simple implementation is (define (zip l1 l2) (foldr (lambda (v1 v2 l) (cons (list v1 v2) l)) '() l1 l2)) Assuming I typed that in right, that is! -------------------------- Sent using BlackBerry
