L.S., I found the Functional Game Engine FunGEn on the web: http://www.cin.ufpe.br/~haskell/fungen/download.html It looks useful, but since it hasn't been maintained for a long time, it doesn't compile. Is there a newer version I can download? -- Regards, Henk-Jan van Tuyl -- http://functor.bamikanarie.com http://Van.Tuyl.eu/ --
