Almost. Or, I'm doing somthing wrong. Here's what I'm doing to test the contents of each of the arrays:

foreach my $key1 ( keys %masterClassHash ) {
print "The class is $key1\n";

foreach my $key2(keys %{$masterClassHash{$key1}}) {
print "\tstatus = $key2\n";

foreach (@{$masterClassHash{$key1}{$key2}}) {
print "\t\tjobids = @_\n";
        }
    }
}

This only yields one jobid per array, when multiple definitely exist.

Thanks, everyone, for your help.
