ADOPTED_FROM:CWA 13849-11:2000 A Control is defined for the Text terminal Unit and two automation objects are defined one each to represent forms, fields within forms. The Text Terminal Control exposes the functionality of the text terminal unit by means of properties, methods and events. It also supports associated interfaces to qualify as a control. Since it is a full control, it can be visually manipulated at design time in any ActiveX enabled development environments like VB. Since data for the Text Terminal is specified through forms, an automation object is defined to represent this form. This object cannot be instantiated directly. It is returned as a result of method or property invocation on TextTerminal control. TTUField is defined in similar fashion as an automation object to represent fields within forms. TTU can support multiple forms and a form contains multiple fields. A dictionary object is used to represent collection of forms and fields. Since the dictionary supports enumeration interface we can either enumerate over all objects in the dictionary or access individual objects through a string key.
