IOW LCLC &FOO in open code and LCLC &FOO in a macro are different variables.
GBLC &FOO in open code and GBLC &FOO in a macro are the same variable.

If the same name is used for a local variable in a different context, it refers to a separate variable. A global variable is the same variable in all contexts where it is defined.
