Hi,

probably the best way is to write a parser using ReadP/ReadPrec and then

instance Read SomeType where

readPrec = yourParser

If you wish, I could send you a few examples (not very interesting, but they 

might help getting you going).

Cheers,

Daniel

Hi,

I am trying to find out how to work with the Read Class for a school

project, i need to declare instances of Read for a few data types.

My problem is that i do not know how to do it, i mean i do not know

how to build a Read instance, i do know about it for the Show Class.

Can some one help?

Thanks
