in thread convert rows to columns

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.
