SCOPE
BrightScript uses the following scoping rules:
Global variables are not supported; however, there is a single hard-coded global variable (“global”) that is an
interface to the global BrightScript component, which contains all global library functions.
Functions declared with the Function statement are global in scope; however, if the function is anonymous, it will
still be local in scope.
Local variables exist within the function scope. If a function calls another function, that new function has its own
scope.
Labels exist within the function scope.
Block statements such as For / End For and While / End While do not create a separate scope.
