Thank you for your answer, Alastair:
The online library report at haskell.org calls it isAlphaNum (not isAlphanum) so it looks as though Hugs is correct.
I've just checked that the name isAlphanum was used in older versions of Haskell and Hugs while Haskell 98 introduces isAlphaNum. It's time for me to remove the old versions of Prelude.hs from my computer! There are, however, pieces of Haskell software around where the old name is used. One example is the Regexp library by Meurig Sage. I will write him about it. Another example is section 9.1 of online Hugs 98 manual. Best Regards, Rysiek
