Hi there

I have a list of ints, with values between 0 and 255 and I need to print them out in little endian form to a file.

I've been using Data.Binary for single values, e.g.

runPut $ do put 'B' put (0 :: Int32)

This will be big endian by default. If it needs to be little endian, use Data.Binary.Put.putWord32le and relatives. With a list, you could do something like: runPut $ mapM_ (putWord32le . fromIntegral) listOfInts I hope this helps. Jed
