I havent done much IO at all in haskell, only within the function itself.
However I want to get the input from the interface for the function and
havent done this before.
In my main function, I want to ask the user what they would like to do
'become fan' for example, then with their choice
I have a suggestion.
Why don't you grab some introductory book on Haskell and learn Haskell syntax a
little?

Hey,
I am studying Haskell as a unit at University. I find the concept and design
idea's of Haskell interesting but I am finding my self struggling to
understand the relationship between the normal state and IO state of
Haskell. This is my situation:
I have created 12 functions for a program

Problem now is reading the data back into the program. When I read the data
back into the program it comes as IO [Track]. This is the code I have been
using to load the data:
loadData :: String - Catalogue
loadData fileName = do x - readFile
Thank you very much for your fast response!
Ok, that is now changed, but everything else in my program is expecting
Catalogue without IO. Is there a way to change IO Catalogue into Catalogue?

Btw. there was a nice article precisely about the issue
Was there? I have been google'ing that problem for ages..
Just one more thing. I have to make a menu system where the user chooses
what functionality they want. Because you cannot change a value once it
is set I have used recursion so that when something changes it then
calls the menu back
