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!

Corion has to finish off some test tickets and hopefully close them. Also I have to prepare some information for the tax people on the weekend :-/
