The example you give is not a complete Haskell program, because it
doesn't contain a function called main.  That is why nhc98 gives
an error.

However, perhaps you really want an interactive environment to try
out your incomplete programs.  In that case, you want to use 'hi'
instead of nhc98 directly.  'hi' provides an interactive prompt for
entering expressions and seeing their results, rather like the Hugs
or ghci Haskell systems.
