Creating, Editing or Inserting Segments

Creating new segments is only possible when a new profile is being created (see above for

instruction for creating a profile at the next available position, or at a position that you

specify). An error is returned if the correct sequence is not followed.

The Insert Segment command is used to add segments to an existing profile (one that

already has an end segment). This inserts a new segment at the position specified.

The Edit Segment command is used to alter segments of an existing profile.

The segment number is in relation to the profile number, e.g. to edit or insert a segment at

position 3 of profile 1 the segment number will be 3, and to edit or insert a segment at

position 3 of profile 6 the segment number will also be 3.
