The DIALOG control class

Inside the dialog instruction, the predefined keyword DIALOG represents the current dialog object. It can be used to execute methods provided in the dialog built-in class.

For example, you can enable or disable an action with the ui.Dialog.setActionActive() dialog method, or you can hide and show a default action view with ui.Dialog.setActionHidden():

BEFORE DISPLAY
   CALL DIALOG.setActionActive( "refresh", FALSE )
