| Usage options |
The SET_REF command is used to assign a component reference to a variable that has been defined with a dynamic reference in the DEFINE_COM statement. With a dynamic reference, an instance of a component is created only when a reference to it is assigned with the SET_REF command.
| Beware of using long object names (i.e. Names) with this command. SET_REF Com(#MyObject) To(*CREATE_AS #MyFormWithLongNames) works with long names. SET_REF Com(#MyObject) To(*CREATE_FROM #MyFormWithLongNames) doesn't work as it is runtime and long names are not available. |
