Nope, no error there. $pi ||= 3 is basically equivalent to $pi = ($pi || 3) which could be described as "If $pi doesn't already have a true value, then set $pi's value to 3." (The 'true' part should not be overlooked.)

So, you could write your assignment as: $list_info{subscribed_message} ||= $subscribed_message; That will set the value of $list_info{subscribed_message} to the value of $subscribed_message, if $list_info{subscribed_message} doesn't exist, or is undef, "", or 0.
