The comment property defines text that can be shown in the comment line when the form item becomes current or when a button receives the focus.

The most common use of the comment property is to give information or instructions to the user. This is particularly appropriate when the field accepts only a limited set of values.

The screen location where the message is displayed depends on external configuration. It can be displayed in the COMMENT LINE, or in the STATUSBAR when using a graphical user interface.

The comment property can, in some situations, be a default placeholder. If the value of the comment property cannot be rendered in a dedicated area (typically, on mobile devices), the comment property value is used as the default placeholder value.

For additional information, see the STATUSBAR and COMMENT attribute topics in the Genero Business Development Language User Guide.
