Re: sorting hashes

[johnnywang]

not sure what you're doing in the sorting of $k2, the following seem to be what you want (not tested):

my $rHash = \%hash;
for my $k1 = (sort keys %$rHash) #outer key, this works
{
  for my $k2 (sort {$a <=> $b} keys %{$rHash->{$k1}}) )
  {
    #display miscellaneous
    print $k1 $k2;
  }
}

The same cmt I already gave to the OP applies: this can't be what he wants for it wouldn't even compile. Correcting the typo indeed this could be what he wants.

Oh, and BTW:

print $k1 $k2;

Aren't we missing something here too?!?

Hello again,
the = sign was a typo that is not present in my original code - sorry about that, same with the print statement - was just to indicate that there was some output.

The solution was indeed to use sort with just $a and $b - yep, Perl is not my first language.

Thank you all for the exceptionally quick replies.

rgds,

There's a lesson in this, and an oft advocated one: do not retype code, paste it. (In this case not much harm was being done, but it's a good general rule to stick to, if possible.)
