And I wasted too much time with formating the output. If you're talking about the problem I think you're talking about, that's the reason I dismissed that approach out of hand. irb(main):001:0> x = Array.new(5, Array.new(5,0)) => [[0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0]] irb(main):002:0> x[2][2] = 5 => 5 irb(main):003:0> x => [[0, 0, 5, 0, 0], [0, 0, 5, 0, 0], [0, 0, 5, 0, 0], [0, 0, 5, 0, 0], [0, 0, 5, 0, 0]] Those references will get you if you're not careful. -- -yossef
