Perhaps I'm missing something, but if you're planning on using arrays, what's wrong with retrieving the item using the array index modulo the length of the array? i.e. let a = [| ... or whatever ... |] in a.(5 mod Array.length a) If accessing an array by index instead of by pointer worries you, then you're looking at the wrong language ;o) David -- Caml-list mailing list.
