[Haskell-cafe] Beginner problems with 'triple' code

26 Jul 2004

      Hi

I'm not especially experienced in using haskell, and I could use some help.

As part of a project, I'm trying to construct a data type that can represent three values as a 'triple' (as opposed to a 'tuple'), and then make a function so that I can sort these values into ascending order.

I'm having a few problems with the code that I have at the minute (I suspect its riddled with errors!)

type Triple = Triple {
    entry 1 :: a;
    entry 2 :: a;
    entry 3 :: a;
    sortTriple :: Triple a -> Triple a;
    } deriving (Show, Eq)
where
    sortTriple t@(Triple x y z)
        | (y
