Hiding Default Action Views
To hide default action views (the buttons that appear on the form when there is no
    specific action view for an action), use the following Dialog class
    method.
Values for the hidden state of the action view can be:
- 0 - 
FALSE, the action is visible - 1 - 
TRUE, the action is hidden 
MENU
  BEFORE MENU
    CALL DIALOG.setActionHidden("next",1)
    ...
END MENU
This example hides the action that has the name next. The reference to the
        DIALOG object was provided by the runtime system.
