Segment Data

The Segment Data is included in the command message when creating, editing or inserting segments (see above). It is provided in two parts (Segment Info A and B).

The meaning of the data contained in Segment Info A and B depends on the type of segment it relates to. Null is shown for unused data, these data values should be set to zero when writing the segment data.
