No, it's not. It's a failed attempt to try to imitate what's outputted
when you use Data::Dumper to print a hash of hashes.
how do I dereference them (all of them)?
C:\home>type test.pl
my %HoH = (
'number' => {
'three' => '21',
'five' => '23',
'one' => 'number',
'two' => '20',
'four' => '22'
},
'alpha' => {
'e' => '103',
'c' => '101',
'a' => 'alpha',
'b' => '100',
'd' => '102'
}
);
# printing examples
print "number - four is: $HoH{number}{four}\n";
print "alpha - e is: $HoH{alpha}{e}\n";
C:\home>perl test.pl
number - four is: 22
alpha - e is: 103
C:\home>
But you need to make an effort with the perl documentation.
perldoc perldsc
perldoc perlreftut
perldoc perlref
Good luck!
