in reply to Hash-O-Array Help

Use parens instead of curly braces when defining a hash 

my %H1 = (
        'THINGS' => ['thing1', 'thing2'],
        'PEOPLE' => ['andy', 'margot', 'dave', 'joe'],
);

    Thanks ccn. Now if I wanted to delete 'dave' I could do ... 
    delete @{$H1{'PEOPLE'}}[2];

    ... but that leaves my hash looking like this ... 
    $VAR1 = 'PEOPLE';
$VAR2 = [
          'andy',
          'margot',
          undef,
          'joe'
        ];
$VAR3 = 'THINGS';
$VAR4 = [
          'thing1',
          'thing2'
        ];
