There are various syntaxes that work, but I generally<br>
use something like this:<br><br>
<br>
#!/usr/bin/perl<br><br>
my %hash;<br>
$hash{first1}{second1} = 'hello';<br>
$hash{first2}{second2} = 'world';<br>
$hash{first3}{second3} = 1;<br><br>
hash_display (\%hash);<br><br>
sub hash_display {<br>
my $hash = shift;<br><br>
foreach my $key (keys %{ $hash
}) {<br>
foreach my $subkey (keys %{ $$hash{$key} }) {<br>
print "key $key, subkey $subkey, " . $$hash{$key}{$subkey} .
"\n";<br>
}<br>
}<br>
}<br><br>
<br>
:~$ perl t.pl<br>
key first1, subkey second1, hello<br>
key first2, subkey second2, world<br>
key first3, subkey second3, 1<br>
:~$<br><br>
