Hi,

I've started messing around with references today and I have a few questions.
I have a hash of a hash %clocks (eg $clock{<name>}{'speed'}) Now I want to read the outer hash in a subroutine. I was reading on references and I think that's what I should use, but I'm not sure of the syntax.
eg 

foreach my $key (sort keys %clocks){
  print_clock_assertions(\{ $clocks{'$key'} });
}

sub print_clock_assertions {
  my($hashref)=$_[0];
  print STDOUT "ref 1 :$hashref->{'speed'}\n";
}

This doesnt work so if you know what I'm at could you point me in the right direction?
