chr and ord not in standard prelude
When I try to use functions chr or ord, I get a not in scope error. If I ":browse Prelude" I do not see these functions. Is there another module I should load?
It looks like these are in module Char:

Don't use chr and ord - they aren't polymorphic, they restrict your code to work only on Chars. Use fromEnum and toEnum (which are in the Prelude) instead. Stefan
