I am trying to pass to hashes to a subroutine and combine into one hash.
Then return that hash as a reference to the main program. Then print the
result of new hash.
%h1 = ("key1" => value1);
%h2 = ("key2" => value2);
$rnew = &mergehash(\%h1, \%h2);
sub mergehash{
%h3 = @_;
return \%h3;
}
print $rnew->{key1};
