Beware: What does that solution do, if `$n > @source`? See: `$ perl -le '@a = 1..3; @b = @a[(@a-5)..$#a]; print "<$_>" for @b;' <2> <3> <1> <2> <3>` [download]	[reply] [d/l] [select]

`@last_n=@source[(@source-$n)..$#source]if ($n<=@scource);` [download] Would be the solution there I guess	[reply] [d/l]
