Globals - when, how, where?
I've been wondering for a while what typical uses Globals can be put to. I understand they are fields that are independent of relationships or tables, and that they have to be on a layout for that layout to use them, but that's just theory. In practice I'd like an idea of their potential uses because I can't work out what to do with them.
Do they substitute for something, are they special links or relationship definers or what? How do you use Globals? What are they good for?
