in reply to convert rows to columns

Hi,

there is something which jumped into my eye: The index of an array runs from 0 to scalar(@array) - 1, so you have to adjust the condition of your for loop.

Best regards

    I saw that, to. Also, you can't push to a sigle element of an array that I'm aware of. You have to push to an array. So the line push $arr[$cnt], $xox[$i]."".$xox[1+$i] I believe won't work. You need something like push @arr, $xox[$i]."".$xox[1+$i].

      In recent Perl (since 5.14), you can push to an array reference. It is not autovivified, though; therefore, 
      perl -e '$x[0] = []; push $x[0], 1'

      works, but 
      perl -e 'push $x[0], 1'

      does not.
