[Haskell-cafe] Functions with side-effects?

[Daniel Carrera]

Hi all,

I'm a Haskell newbie and I don't really understand how Haskell deals 
with functions that really must have side-effects. Like a rand() 
function or getLine().

I know this has something to do with monads, but I don't really 
understand monads yet. Is there someone who might explain this in newbie 
terms? I don't need to understand the whole thing, I don't need a rand() 
function right this minute. I just want to understand how Haskell 
separates purely functional code from non-functional code (I understand 
that a rand() function is inevitably not functional code, right?)

Cheers,
Daniel.
