If you're only streaming data, it probably would be. However, you seem to keep some of it in memory, which is what the problem is. You might be able to fix this by doing "main = readFile filename >>= liftM separateOutput >>= mapM_ foo". However, it depends on what separateOutput does. Also, consider using when (from Control.Monad) instead of your if statement. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
