In my program, I use the function "isDigit", which is part of haskell98.Data.Char

When compiling my program, I get the error: Variable not in scope: isDigit. The same error occurs when I explicitly use the package haskell98 as in the following command-line.

Are you remembering to add "import Data.Char" to your program?

Ah, thanx. That was the problem. Indeed, I assumed that did not have to give a package option and also that there was an implicit "import" in my Haskell Program, which is not the case. Regards, Marco
