The documentation offers a couple ways; the most common idiom uses a hash, as other people have shown. However, you can leave the hard work to Perl if you use the Tie::Array::Unique module, available on CPAN: http://search.cpan.org/~pinyan/Tie-Array-Unique-0.01/ Basically, if you do: use Tie::Array::Unique; tie my(@data), 'Tie::Array::Unique'; and then use @data normally, it will make sure you don't duplicate any elements. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ CPAN ID: PINYAN [Need a programmer?
