Whenever you specify an event to occur with a given dialog element, the
dialog editor generates
code containing the Natural system variables
*CONTROL,
*DIALOG-ID
and *EVENT.
During the processing, *CONTROL
contains the dialog element's handle, *EVENT
contains the event name and *DIALOG-ID
identifies an instance of a dialog.
You can reference these system variables whenever you enter Natural code within the dialog editor. If, for example, the end user clicks on a push button control and the event handler calls a shared subroutine, you can use these system variables as logical condition criteria to trigger the subroutine.
For further details on these system variables, see the System Variables documentation.
