ControlField Attribute
Data Type: smallint
4GL Access: RW
The ControlField attribute determines whether a field is intended for manipulating the user interface rather than the underlying data. A control field plays no part in determining an ancestor's HasDataChanged value.
Valid values are TRUE or FALSE.
Default: FALSE
Control buttons and viewport fields are two fields for which you might set this attribute to TRUE.
