add something to a list
Sun, 17 Feb 2002 09:20:07 +0100
I'm a poor lonesome newbie in Haskell world, and I would like to add a string
typed on the prompt to a list of strings which is already defined.
It would look like something like :
type Path = [String]
currentPath = 
getpiece ::IO String
getpiece = do c <-getLine
putpiece a = a:currentPath
and then I could combine the two functions, but obviously it doesn't work.
I dare understand that it's impossible isn't it ?
Maybe the only way is to create a new [String] each time I want to add a new
string ? No ?
