Thanks, Brock. That is exactly what's happening in this script. Your
explanation helped clear things up for me.

I'm reading through Intermediate Perl, as pangj suggested, but I have
one other question. If the above line is the same as writing:
my $item = $catalog->SurfDB::split_line($itemid);
as you suggest, why use one over the other? Is it just a matter of style, or
is there more to this than meets the eye?
Thanks again,
Marc
