This problem hopefully has a simple answer, but I can't find it. I have a hash of hashes. All I'm trying to do right now is print out all of the values to make sure that the hash got populated correctly. No matter what I do, it doesn't work.
First I tried:
my %prochash;
# sub call to populate hash
for (my $i = 0; $i < $prochash{NumProcessors}; $i++)
{
 foreach (keys ($prochash{'Processor$i'}))
 {
   print "$_ : ",$prochash{"Processor$i"}->{$_},"\n";
 }
}

This yields the error "Type of arg 1 to keys must be hash (not hash element)". Fine.

Next I tried:
foreach (keys %($prochash{'Processor$i'}))
I've seen this notation several times on PM, but it gives me the error "Use of 'keys' without parens ambiguous". *Sigh*

So, my next attempt was:
foreach (keys (%($prochash{'Processor$i'})))
This one gives me the error "Scalar found where operator expected". Rrrrrr

The last error leads me to think that maybe I'm putting the parens in the wrong place, but I can't think of anywhere else they can go. If I take the parens off of around the "keys" part, I get "Missing $ on loop variable".
This is really starting to drive me batty! If it makes any difference, I'm running ActiveState's port of 5.60. Thanks!
