Reading and processing data file

[Ramachandran M]

I'm working on an assignment at my uni that requires me to prompt the user 
for an input and to locate that item in a data file. For example, if the 
user enters a flight no. of IC009, the program should locate that particular 
record in the file and output the flight's origin and destination. How 
should I go about writing this in Haskell? Any pointers would be greatly 
appreciated. Thanks.
