Every time I try to use [underscore] in an definition it says something like the symbol /017 is not recognised

Could that be \017, i.e. octal 17 (defined in ASCII as SI, whatever that may be)?

SI is Shift In, if I remember correctly, not that the operation of devices like Flexowriters is of any relevance. However, I'd guess that it's hexadecimal 17, because ord '_' `rem` 16 == 15 == 0x17. So for some reason it's talking about the botom four bits of '_'!

Any help suggestions?

Wild guess: Are your files using the same character set as your Haskell system is expecting? I know Windows pulls some occasional stunts with the character set (and occasionally lies about it), but I wasn't aware that it affected underscore.

Windows is a mystery to me, however. My guess would be something translating from one page of a character table to another. What locale are you in? Jón -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk
