By default, PowerBuilder makes static lookups for functions and events. This means that it identifies the function or event by matching the name and argument types when it compiles the code. A matching function or event must exist in the object at compile time.
Static calls do not guarantee that the function or event identified at compile time is the one that is executed. Suppose that you define a variable of an ancestor type and it has a particular function definition. If you assign an instance of a descendent object to the variable and the descendant has a function that overrides the ancestor’s function (the one found at compile time), the function in the descendant is executed.
