Hello Perl Gurus,
I'm trying to write a program that will merge two hashes together onto a
third hash called %h3. I need to
return a reference to %h3 to the main program and print each of the values
of the hash %h3 using the arrow notation.
Name of the actual function performing the merge
one : 1
six : 6
three: 3
two : 2
Wags ;)

In the example you provide, this will work:
-START
%h1 = (one = 1, two = 2, three = 3);
%h2 = (four = 4, five = 5, six = 6);
# Note that the '' on function calls is optional, unlike $, @, and %
$ref_h3 = mergehash(_, _);
sub mergehash {
my ($rh_first,
