Variables exist in scope. Apart from assembly language, where
registers have universal scope, every language I know of has some
concept of scope. (REXX is very different from most, in that
"PROCEDURE EXPOSE" isn't at all your classic notion of scoping, but
there's still the concept that there can be two variables with the
same name.) When you create one, you create it in a particular scope,
and that's how it must be.
