The first record of a set is a feature record containing basic information for a feature, followed by other coordinate records. Following the coordinate records are optional text and attribute records. The entire record must be shorter than 510 characters. Blanks in fixed-format character fields are interpreted as blank characters rather than as null values. There is a maximum of 15 attribute values in this record.
More attributes can appear in the attribute continuation record.
The label record defines the position and the orientation of the label for the feature on the previous feature record. The position is given with x and y coordinates. The orientation is set using an orientation angle in decimal degrees. The records representing the polygon relationships file are described in tables 24 and 25. The first record is a description identifying the record as the primary schema file.
