My first reaction was to use a hash but it's memory consumption would be way too much.
Wait! I thought you said your entire data is only 10 meg! You could have a hash of all the FIELDs and still probably use up less memory than your STDIO buffers! Or did you mean something like "10 gig" instead of "10 meg"?
