Formatted in this way should be compile:

linerFind :: [Int] -> Int -> MaxSA -> MaxSA      --MaxSA is  MaximumSubarray
linerFind xs len  ms1@(MaxSA l h m)             -- (MaxSA leftPosition rightPosition maxsum)
  | h<len = keepFind ms1                             
  | otherwise = ms1
  where keepFind ms'@(MaxSA l' h' m') = let ms2@(MaxSA l2 h2 m2)= find' xs l' (h'+1)
                                                                          in if m < m2 
                                                                              then linerFind xs len ms2
                                                                                       else keepFind ms2

sorry and please forget the name and what it is meaning for.
just look at in syntax aspect


the error : "parse error on input `|'
Failed, modules loaded: none."



linerFind :: [Int] -> Int -> MaxSA -> MaxSA   --MaxSA is  MaximumSubarray
linerFind xs len  ms1@(MaxSA l h m)             -- (MaxSA leftPosition rightPosition maxsum)
  | h<len = keepFind ms1                             
                where keepFind ms'@(MaxSA l' h' m')=
                    let ms2@(MaxSA l2 h2 m2)= find' xs l' (h'+1) in
                    if m < m2 then linerFind xs len ms2
                    else keepFind ms2                                 
  |otherwise = ms1                                      --compiler say error is in  this line
