A global variable is a variable that you can use in any script or procedure in an application. It contains data that any script or procedure in the application can access. After you declare a global variable, it is available for reading and writing by any script or 4GL procedure in the application. If you change the value of the global variable in one frame, the new value is immediately available to all other frames and 4GL procedures in the application.

You declare global variables using the Global Variable Editor.
