I have a hash of hashes and I want to list the inner hashes $names in the order they've been entered into the hash. I know I can't use "keys" but I use keys to get the number of items with the following two lines of code ...

@myArea = sort (keys %{$camArray{$trafficArea}});
$items = scalar @myArea;

Then, I can use a "for" loop to print out each name ...

for ($i=0; $i < $items; $i++) {
    print "\t<option>$myArea[$i]\n";
}

but this of course uses the keys sort. So I've been trying to do something along the lines of ...

for ($j=0; $j < $items; $j++) {
    print "$camArray{$trafficArea}{$j}\n";
}

to get at the values in order, all to no avail. Is there a way to get at the entries in a hash in order? Here is the hash of hashes I'm using ...

%camArray = (
    'seattle' => {
        ' Select a Traffic Cam' => '',
        'I-5 at NE 45th St' => 'cctv135',
        'I-5 at Roanoke St' => 'cctv126',
        'I-5 at Yesler Way' => 'cctv105', 
        'I-5/I-90 Interchange' => 'cctv812',
        'I-5 at Holgate St' => 'cctv098',
        'I-5 at Spokane St' => 'cctv093',
        'I-5 at Albro Place' => 'cctv086',
        'I-5 at Mid Boeing Field' => 'cctv081',
        'I-90 at 18th Ave. S.' => 'cctv821',
        'I-90 Midspan' => 'cctv859',
        'Hwy 520 at Montlake' => 'cctv504',
        'Hwy 520 Midspan' => 'cctv509',
        'Hwy 99 at Michigan St' => 'cctv498',
        'Hwy 99 at W Marginal Way' => 'cctv497'
    },
    'tacoma' => {
        ' Select a Traffic Cam' => '',
        'Narrows Bridge - westside' => '016cc0085',
        'Narrows Bridge - eastside' => '016cc0047',
        'I-5 south of Tacoma' => 'TacSouth',
        'I-5 north of Tacoma' => 'TacNorth',
        'I-5/Hwy 16 Interchange' => '005cc1324',
        'I-5 at S. 48th Street' => '005cc1312',
        'Hwy 16 at Center St.' => '016cc0019',
        'Hwy 16 at Pearl St.' => '016cc0037'        
    },
);
