title: How do you sort parallel arrays in Perl?
body: <p>I have a few arrays of the same length. I want to sort the first array, and make all the others array "sort" accordingly. For example, if the first array is <code>(7,2,9)</code> the second is <code>("seven","two","nine")</code> and the third is <code>("VII","II","IX")</code> after the sort (ascendingly according to the first array values) we will have <code>(2,7,9)</code> <code>("two","seven","nine")</code> and <code>("II","VII","IX")</code>.</p>
  
  <p>How can I do that?</p>
