The DATA_EXCHANGE object can be used to exchange data between several windows in an interactive Visual Adelia program, or between several interactive Visual Adelia programs running simultaneously on the same machine.
The data is sent via the VALIDATE method.
Any DATA_EXCHANGE object that manages this data (i.e. with the same property value NAME_DATA) receives a DataChange event if it is connected (and if this event is defined for the object) on which it can process the data.
The next validation causes the data to be replaced by new values, and the old values become inaccessible.
The object is invisible when run.
Note: This object is not supported by the Java generator.
