It may be simple to do once you understand, but your past several questions 
relate to

- purity

- do-notation as syntactic sugar for monadic computations

- the IO monad

If you understood these things you would not be running into this trouble, 
or you would quickly see the problem yourself. Because most books and 
tutorials introduce these things gradually, giving you lots of practice 
problems /at the level they are introduced/, I think your learning process 
would go more smoothly if you

- pick a single book. don't try to digest all these different tutorials and 
books at once

- read it sequentially

- work the problems. if you want to branch into your own problem, stay 
close to the examples you've seen so far

Best wishes,
Mike
