[Haskell-beginners] Actions v. Functions

[MJ Williams]

For example, `main = do input <- getLine ...', where `getLine' is an 
action as distinguished from a function such as `main'.  Other 
examples of actions in Haskell include `print', `putStrLn' and any 
process that reads from or writes to a file. Of course, the list of 
actions doesn't end there, though the examples here should answer 
your question.
Sincerely,
Matt
