Hi, just use the "<-" in the Monad like
... do t <- f -- where f has the type IO(Something) -- use t which is of type Something ... return t -- makes an IO(Something)
Btw: This thread might fit better to the haskell-cafe list. Georg On Tue, 11 Nov 2003 00:37:54 -0800, Ryoko Nanase <nptg400@hotmail.com> wrote:
Hello, everyone.
I learned 'return' function which makes any type t to IO t. Is there any way to makes any IO t to type t? I want that method because I need only the value of input, without printing any output. You might tell me another way to do it if the transformation of "IO t" into "t" is not required. Thanks in advance.
Peace,
Jason
