This is a FAQ, you can bring it up at perldoc -q "duplicate" In short, there is no built-in way to do this. The hash is the usual method for disallowing duplicates (in the keys). The most elegant solution from the FAQ is (in my opinion) to use hash slices to avoid a loop: @duparray = (1..10, 1..10); @[EMAIL PROTECTED] = (); @uniquearray = sort keys %tmphash; Hope this helps.
