Tie::FlatFile::Array is a Perl extension which treats a flatfile database as an array of arrays. This module allows the programmer to treat a flatfile database as as array of arrays. For example, lets say you have a datafile that has fixed-length records like so: Field-name Type URL ASCII characters, length 30 Referals Integer, 4 bytes, binary in network order If you were going to use pack to create a record like this, youd use a format string of A30N. Since Tie::FlatFile::Array does the packing and unpacking behind the scenes, you would use that pack format string in the call to tie: tie @flat, Tie::FlatFile::Array, data.file, O_RDWR | O_CREAT, 0644, { packformat => A30N } or die("Tie failure: $!"); To insert an item into the data file, you would assign an array reference to one of the arrays elements like so: $flat[0] = [ www.yahoo.com, 3601 ];.
