Exactly. But if the alias is not USED(), then he assumes its TYPE()

will be "U" so he doesn't have to close it. And I believe it works

without having to address work areas, at least within the current

datasession. I'm not sure it would work across datasessions though,

but it's an interesting alternate approach.
