To interate over something like:
$abc{'a1'}{'b1'} = $number1
$abc{'a2'}{'b2'} = $number2
$abc{'a3'}{'b3'} = $number3
$abc{'a4'}{'b4'} = $number4
...
You can use:
foreach my $key1 (keys %abc) {
foreach my $key2 (keys %{$abc{$key1}}) {
my $value = $abc{$key1}{$key2}
print "Key1=$key1 Key2=$key2 Value=$value\n";
}
}
