How do I process an entire hash?

Use the each() function (see each) if you don't care whether it's sorted:

    while (($key,$value) = each %hash) {
        print "$key = $value\n";
    }

If you want it sorted, you'll have to use foreach() on the result of sorting the keys as shown in an earlier question.
