Tsk, tsk, Evanovich. As a good acolyte you know that you will get a much more generous response if you show us a little code from your own attempt to address this problem.

Failing that, you might share some of your thinking about why the most obvious solutions might not be the optimum you are looking for...

Also, some information about this file would be helpful. Do you have control over its format? If not, what is the form of the data stored there? It's tough to offer a solution when we don't know what the data looks like or how much freedom there may be in determining its form.

Update: /me smiles encouragingly at Evanovich noting that his solution uses the same basic approach as that of the honorable cLive ;-), differing mostly in the use of intermediate temporary values and a couple inadvertant errors.
