Thanks for your assistance. I'm using now Notepad.exe . Before I did it in Wordpad. I use Windows XP. I'm trying to solve this nasty problem

Subject: [Haskell-cafe] a newbie's question
Hi, I'm trying to investigate the list monad. I program
instance Monad [] where
xs >= f = concat ( map f xs )
return x = [x]
a = [1,2,3]
b = "there"
do { x <- a
y <- b
return (x , y) }
And I get the error
Syntax error in input (unexpected backslash (lambda))
