Keep in mind that a function's result depends only on its parameters, so any state you want to retain must be part of the parameters. So you might be looking for something like: iterateN x f y = if x == 0 then y else iterateN (x-1) f (f y) -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
