[Haskell-cafe] How to hold common data

[scott west]

Hello all,
    I'm new to haskell and was just wondering if there was any efficient 
or standard way to store and modify some sort of state data. The 
functional nature of haskell has me confused in this respect! Basically 
what I want to achieve is an interactive program that allows you to edit 
some tables, and thus hold some data. I dont' need to be spoonfed an 
answer, but a general guideline would be very helpful :) Thanks for any 
help you could provide!

Regards,
Scott
