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.
