To clarify passing values to a subroutine
The arguments for a subroutine are treated as a list assignment to the @_ list. This script demonstrates a few key concepts:

my @entry = ('ListItem1', 'ListItem2');
$ScalarContext = &get_throughput($Var1, $Var2, @entry, $Var3, \@entry)
+;
@ListContext = &get_throughput($Var1, $Var2, @entry, $Var3, \@entry);

sub get_throughput {
  my $GetsVar1 = shift @_;       #@_ is a list of your arguments
  my $Scalar = shift;            # gets $Var2, @_ is the default for s
+hift
  my ($List1, $List2) = @_;      #@_ your list was added to @_ as indi
+vidual elements
  my (undef, undef, $Var3) = @_;  #undef discards return values
  my $ListRef = $_[4];           #a reference to your list
                                 #see docs for more info on refs
  return wantarray ? @list : $Scalar;
}
