How to reverse a HASH into string format?

I have defined a HASH like following:

my %data = ("name" => "Paul",
"age" => "100",
"address" => {
"street" => "1234 test st.",
"city" => "my town",
"zip" => "12345"
});


But now I am trying to dump this hash into another file, and I want it to be
in the same format since it will be used by another script later on. Is
there a build-in functions I could use in perl?

Thank you

From perlfaq4:

# To store the data:
use Storable;
store(\%data, "filename");

# To retrieve the data:
use Storable;
my %data = %{ retrieve("filename") };

In addition to mlj's Storable suggestion, have you considered going all
the way and putting this shared variable in a module? That way you
need only define the hash once, and any script that uses the module
will have access to it.
