If I might interject a meta-comment: your use of the word "statement" (or, more precisely, "stmt") in your subject line explains most of the difficulty you were having; in expression-poor imperative languages, you have to "get things done" by using a sequence of statements to cause a series of mutations to the program state. In functional programming, that's not necessary. In any case, I'm delighted to see that the functional solutions make sense to you! John "fp cheerleader" Clements
