I get "found HASH(0xacacfe8)".
That's a reference to a hash. It sounds as if you might want to ask
the question "Is that hash empty or not?", which the keys() function
can answer:
if (keys %{ $ref->{'order_number'} }) {
print "There's something in the order number hash.\n";
} else {
print "Hash is empty.\n";
}
If you use keys() in a list context, you'll get a list of the keys of
the hash. Hope this helps!
