References as Return Values

References & Structures References as Return Values

References may be returned from subroutines

sub Test {
	$myHashReference = { 'a' => "ape", 'b' => "bat" };
	return( $myHashReference );
}

The return values may then be dereferenced

$myHashRef = &Test();

foreach $key ( keys %$myHashRef ) {
	print "$key = $$myHashRef{$key}\n";
}
