[Haskell-beginners] ord

[allan]

Hi

These are both defined in the module Data.Char, I guess they were in the Prelude when the book was written.

GHCi, version 6.8.3: http://www.haskell.org/ghc/  :? for help
Loading package base ... linking ... done.
Prelude> :m Data.Char
Prelude Data.Char> ord 'a'
97
Prelude Data.Char> chr 97
'a'
Prelude Data.Char> 

Remember you can use hoogle to look up library functions:

regards
allan
