Hi Shachar,
First you can always use Data::Dumper:
use Data::Dumper;
print Dumper($ref);
To make sure that the data is stored correctly.
In regard to your question:
my $ref;
my %hash = %{$ref};
foreach my $ptrelem (keys %hash) {
my @array = @{$ptrelem};
foreach my $item (@array) {
print
Sorry a mistake...
foreach my $ptrelem (keys %hash) {
Should be
foreach my $key (keys %hash) {
my $ptritem = %hash-{$key};

Noam beat me to it, but here's perl solution without additional variables:
#!/usr/bin/perl
%hash = (a=['moo','goo','woo'],
foo=3,
baz=5);
$ref = \%hash;
foreach my $elem (@{$ref-{a}})
{
print $elem\n;
}

Hi Dov,
Yes, it works. Now can you, please, explain to me why? What

{ } in Perl are casting when they surround a value
And the second set of { } around the 'a' mean variable of Hash

Okay, I'm sorry for being difficult. I really couldn't find the answer
in the Perl documentation.

not surprised as this is one of the funky places of Perl 5.

err, I don't think that casting is the right word to use here. What

All that is left is understanding why the round braces around the whole
expression.
Oh, the syntax of foreach

Probably you got the anwer from the responses of others already, in
any case you can use constructs such as theses

That's 0 of course, or even remove altogether and just leave the
12 part. Same problem remains, however.

I'm trying to create a perl program that will recurse into

You should use my $dirname = shift; instead of local here. It's safer.
opendir DIR, $dirname or die Couldn't

Probably you should use File::Find
Try this code as a starter:
use File::Find;
$dirname = shift @ARGV;
find(\myfunc, $dirname);
