A type of group which specifies a position and display area. The area may be used by other elements e.g. PAGE, or as a "clip region" - see CLIP attribute. Fields can be defined in terms of other fields (including any special ones such as the time) or a value obtained by prompting the user; see Double page example.
If the named field has not been defined already in an associated .EE field file, the area's coordinates are constructed from the IDF position attributes. If the named field is defined in the .EE field file, the display's coordinates may be taken from the EscapeE field instead: see DEFINE attribute.
