Dear staff, I am currently working on an assignment with requires us to write in Haskell. I am having trouble with "pipeline". The required textbook called, "The Craft of Functional Programming" 2nd Edition. There is a pipeline example, which I find it useful in my assignment, but for some reason, there may be a typo in the pipeline syntax, which is ">.>". Coz it doesn't compile @_@ I have attached a file of the example, I found from the book. There is a website where I could download the entire book. It's got the same stuff as in my textbook. Please help me, coz i've tried even Unix's pipeline syntax which is obviously wrong... I'm not desperate, please reply, thank you very much. Sincerely, Jack This is the output of the compilor... /*********************************************************************/ Haskell 98 mode: Restart with command line option -98 to enable Reading file "C:\PROGRAM FILES\HUGS98\lib\Prelude.hs": Parsing........................................................
