Thanks a lot Neil, I will definitely read it. I searched google and found the same article here for free http://www.cs.chalmers.se/~emax/wired/documents/LP_HFL07.pdf I didn't know that Haskell commuity is so alive. Much more answers in much less time than when I wrote something to jav:) Fero Neil Mitchell wrote:
Hi
Hi I have read in one tutorial (I can't find it again, but it was probably either one on ibm, gentle introduction or yaht), that it is possible to define relationships between free variables and the same program can be used to calculate either first variable when second is set or second when first is set.
Here is how to do it in Haskell:
