A script that I'm refactoring has global variables in two different styles, e.g.:
$main::global->{form}->{'mailprog'}
$main::global->{form}->{mailprog}
The quote marks don't seem to make a difference, so what would be the
advantage of using them? What are they and what do they do? I don't recall
seeing anything like this before.
Thanks,
Marc
