Natural for MBCS provides the option to create boxes for map fields. Boxes help outline particular fields and provide for a more clearly structured screen layout.
Boxes can be created with either the outline editor or the map editor:
The outline editor is the primary tool for creating boxes. It provides
a convenient way to draw a box directly in the field location within the
editing area. This is achieved by setting box codes, for which equivalent
BX parameter values are generated into the map source.
Detailed instructions are provided in Using the Outline Editor.
The map editor can be used to define boxes by adding or changing the
BX parameter settings for the field around which you
want to draw a box.
The BX parameter can be set in the
BX field of the extended field editing area, which is
invoked with the
extended
field editing function described in the Map
Editor documentation. In the BX field, you can
enter a combination of valid parameter values as described for the
BX session parameter and listed in
List of Box Codes and BX Parameter
Values.
