Unless I'm missing something, this task is easier than it sounds. Since you
are interested in only a small part of the record, the memory requirements
are quite modest so you can absolutely fit it all into memory while
processing the file one line at a time. If I understand your problem
correctly, a hash of arrays or objects would make short work of this.
