Thanks. I removed the hPut and it runs smoothly. I had forgotten that
haskell chooses the types dynamically.
Shouldn't haskell pick up that there is no 'mod' for Word8? I mean,
shouldn't I get a nicer error message?

Well, it inferred Word8 for your generated values, so 256 overflowed to 0.
Stating the expected type here would prevent that. (And is why mandatory
top level declarations are good -- they can prevent bugs caused by
an unexpected type being inferred).
