Passing two array references.

[LucL]

Hi,

I'm trying to pass 2 arrays to a subroutine, but I wan't the subroutine to be able to manipulate the arrays directly (and not eat up memory recreating them).

How can I pass these 2 arrays to the subroutine. I know I have to pass them as a reference but I don't know what the sub should look like (as far as parameters) or whether i should pass as \@arr1 or @arr, etc.

I know that I can access the first array by looking at $_ in the sub but what would the second one be?

Simple example would work. Thanks guys!

You shoukd pass them link this

test( \@array_1, @array_2 );

sub test {
	my ( $arr1, $arr2 ) = @_;

	for my $item ($@arr1) { print $item . "\n"; }

	for my $item ($@arr2) { print $item . "\n"; }
}

probably just a typo, but this is missing a backslash:

test( \@array_1, @array_2 );

should be:

test( \@array_1, \@array_2 );
