Hi Monks!
I am passing values to a subroutine and sometimes in my code I don't need to pass all the values expected by the sub, and I know I am getting an "Use of uninitialized value..." from the expected values in the subroutine. OK here is the passing sample code: 
...
my $info = send_values(
                           {
                             name   => $name,
                             address    => $address,
                             id  => $id,
                             pic         => $pic,
                 }
               );
...

Here is the sample sub code:
...
sub send_values{
  
  my ($args) = @_;

  #test:
  my $values = "Your Results are:\n
                $args->{name}\n
                $args->{address}\n
                $args->{pic}\n
                $args->{id}\n
                $args->{zip}\n
                $args->{phone}\n
               ";

}

These two "$args->{zip} and $args->{phone}" will give me warnings on "use of uninitialized value" because I am not passing them. Can I use some sort of "if @_ defined" to prevent this issue?
Thanks for the help!
