Hi, I am very new to haskell and the program hugs and I am having problems using the wildcard operator _ Every time I try to use it in an definition it says something like the symbol /017 is not recognised. I am sure my defintions are correct as I tested it with an example defintion from Alan Thompsons craft of functional programming book. I am guessing that all the relevant modules have not been loaded properly. I have reinstalled hugs with full implementation and this has not helped. I am using a windows 98 PC. Any help suggestions? Or has anyone just got the wildcard definition which are could just paste into my scripts Many thanks --------------------------------- Yahoo!
