DF_INDEX_SEGMENT_FIELD (Integer)
The number of the column in the current segment. There must be an Index_Segment_Field line for every segment in the index.
For example, if we want to define index 4 as having three segments where segment 1 is column 5, segment 2 is column 3 and segment 3 is column 2 this would look like:
Index_Number 4
Index_Number_Segments 3
Index_Segment_Field 5
Index_Segment_Field 3
Index_Segment_Field 2
