Re^4: Test if multiple variables are defined

[stroke]

Thanks, that's what I was trying to say - run it on each element, not the array as a whole. Words failed me at the time though. And a simple solution - I went for:

for ( $ipaddress, $prefix, $interface, $device, $location, $comment ) 
+{
  s/^\s+|\s+$//g if defined;
}

Thanks for your wisdom!
