Hi all:
I'v been learning haskell for several months, and now I'm trying
to write some real word program in haskell, like finding files under
one directory or something
My problem is that, I dont know the way of writing a loop in
haskell. I searched google and found some code that

val - peek value
if val == 0 then return () else do

Recursion replaces loops. If it needs to be monadic or not depends on what
you want to do.

Thanks for your quick reply. So recursive and monad is the proper
way to simulate loop,right?
Well, recursion (either explicitly or implicitly via map, fold, etc.)
rather than iteration (i.e. a loop) is the usual approach in

I kept close to your suggestion, but avoiding monads, especially IO, is a
good idea. If you do not need low-level memory access with peek and poke,
