Hi, My Prelude docs must be out of date because chr and ord don't seem to be there. How do I access these functions?

Michael, those functions are not in the Prelude, they're in Data.Char.

Michael, those functions are not in the Prelude, they're in Data.Char.
But they're not really necessary anyway: Prelude> fromEnum 'A' 65 Prelude> toEnum 42::Char '*' -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk http://www.chaos.org.uk/~jf/Stuff-I-dont-want.html (updated 2009-01-31)
