Coding Problems!! Please help

[Jack Tsai]

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
