Hi,

Thanks for the reply. Ok, I'm working on a wiki (which can have VERY large articles in). The site also gets a lot of traffic (several million hits a month), so I need to make this code as optimized as possible. Now, lets say we have: 
sub process_article {
    my $article = get_article_from_db($article_id);
    my $contents = process_article($article->{contents});
    # now I need to access $article->{contents}, but the modified vers
+ion from process_article
}

sub process_article {
    my $article_contents = $_[0];
    # do some stuff to $article_contents here
    return $article_contents;
}

[download]
..so basically I wanna be able to pass along $article_contents to different functions, but not actually have it take up more memory (or require a "return", to assign it to a new variable).

Does that make more sense?

TIA

Andy
