Description
In PowerBuilder 7, you work with global functions in the Function painter and object-level functions in the Application, Window, User Object, and Menu painters.
Usage
Whether you're working with global or object-level functions, you work with the Script, Structure, and Structure list views. For object-level functions, you also use the Function List view.
When you add a new function, a Prototype window displays above the script in the Script view. The fields in the Prototype window are in the same order as the function's signature: access level, return type, name, and then for each parameter, how it is passed, its data type, and its name.
