FYI Perl stops processing when it sees __DATA__ so there would be no problem loading a script that is over 4 GB of size. As for the use of a hash of arrays, reading the post I would assume a badly chosen data sample rather than a misunderstanding.

Update: Good catch, eye. The sample ws well chosen.
