In 1.9 you can do

@data = File.foreach(file_name).map {|l| l.chomp.split /\t/}

In 1.8 you'll need something like

require 'enumerator'
@data = File.enum_for(:foreach, file_name).map {|l| l.chomp.split /\t/}

or this which should work in both

@data = File.readlines(file_name).map {|l| l.chomp.split /\t/}

Kind regards
