Hello akki_best, and welcome to the Monastery!

$var1 = $var2; $var2 = $var1;

That won’t work, because by the time you get to the second command, the value of $var1 has already been overwritten by the first command. But in Perl, swapping these values is as simple as:

($var1, $var2) = ($var2, $var1);

P.S. Please format your code using <code> tags. See Markup in the Monastery.

Hope that helps,
