Would someone be so kind as to explain the following, or at least point
me to further reading?
$item =
$main::global->{open}->{catalog}->SurfDB::split_line($main::global->{form}->{'itemid'});
The part I'm having trouble understanding is
"$main::global->{open}->{catalog}->". What does that do to the split_line sub
that's being called? What does it do differently than just calling
SurfDB::split_line($main::global->{form}->{'itemid'}) by itself?
Thanks,
Marc
