Hi stefan,

One way you can build up an structure which mimics

> Arraydog = 12, 98, 32
> Arraycar = 14, 67

might be:

ratdog:~ mike$ pry
[1] pry(main)> records = Hash.new { |h, k| h[k] = [] }
=> {}
[2] pry(main)> records[:dog] << 12
=> [12]
[3] pry(main)> records[:dog] << 98
=> [12, 98]
[4] pry(main)> records[:car] << 14
=> [14]
[5] pry(main)> records[:car] << 67
=> [14, 67]
[6] pry(main)> records[:dog] << 32
=> [12, 98, 32]
[7] pry(main)> records
=> {:dog=>[12, 98, 32], :car=>[14, 67]}

Hope this helps,

Mike
