Re^2: dynamic hash name

in reply to Re: dynamic hash name
in thread dynamic hash name

So for the first option: How do I iterate? Because at the end this is what I want to do.

        for my $key ( keys %citystate ) {
                $fhdest -> print("<p>$key</p>");
        }
        for my $key ( keys %citycountry ) {
                $fhdest -> print("<p>$key</p>");
        }
        for my $key ( keys %airportCode ) {
                $fhdest -> print("<p>$key</p>");
        }

`$data{citystate}` contains a reference to a hash, so where you had `for my $key ( keys %citystate ) {` [download] you now use `for my $key ( keys %{ $data{citystate} } ) {` [download]	[reply] [d/l] [select]
