It sounds like you want the stop-before and stop-after functions, or possibly the for/first loop. http://docs.racket-lang.org/reference/sequences.html?q=sequence#(def._((lib._racket/private/base..rkt)._stop-before)) http://docs.racket-lang.org/reference/sequences.html?q=sequence#(def._((lib._racket/private/base..rkt)._stop-after)) http://docs.racket-lang.org/reference/for.html?q=for/first&q=sequence#(form._((lib._racket/private/base..rkt)._for/first)) --Carl _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
