Well, actually, this was scanned from a book but the OCR process wasn't 100% effective. So, I was hoping the list would easily identify and replace the erronious characters.
Thanks for trying, anyway.

Well, I don't know if it is by encoding of letters in your e-mail, but what do you expect that
[a | a . xs, a x ]

Yes, sorry, I missed the firt line of the algorithm when I was pasting it into the email. Okay
qSort [] = [x]
-- and even
qSort [x] = x
The code fragment below still doesn't work.

qSort (x:xs) =
    qSort smaller ++ [x] ++ qSort larger
    where
    smaller = [a | a . xs, a x ]
    larger = [b | b . xs, b > x ]

Cheers
