You can use the special variable `$,` to do that: `$, = "\t\t"; print @array;` [download] See `perldoc perlvar` and search for `$,` to see an explanation of what it does. See also `$"`. HTH -- YAPC::EU::2005 is in Braga, Portugal.	[reply] [d/l] [select]

You may want to do 'local $, = "\t\t";'. Probably not a big deal on this one, but I try to always use local when I reassign a global.	[reply]

You can also `my @array = ("first","second","third"); my $output = join( "\t\t", @array ); print( $output );` [download]	[reply] [d/l]
