Subroutine declaration incorrectly allows return type to be defined
A subroutine is defined as a function shortcut which returns type void, by either explicitly calling, “return“ or not including a return. The BrightScript subroutine incorrectly allows a subroutine to declare a return type allowing the subroutine to compile. A subroutine can “return” or not include a return, but if a subroutine should return a variable, we recommend declaring a function with a return type.
See Program Statements | ProgramStatements-Function()AsType/EndFunction for more information about subroutines and functions. It correctly mentions that a subroutine only returns a void type (“The
...
Sub
...
statement can be used instead of
...
Function
...
as a shortcut for creating a function with return type Void").
