Three level offset indexing
When using three level offset indexing, the image address assigned to each document is defined as follows:
•Field D (Level 2) defined as having a field length greater than 0.
•Field C (Level 3) defined as having a field length greater than 0.
•Fields B and A may be defined as fixed fields if desired.
For example, if you scan a book with two sections (Section 1 contains 2 chapters, each having 40 pages; Section 2 contains only 1 chapter, having 120 pages) the image address has been defined:
•Field D has 2 characters
•Field C has 1 characters
•Field B has 0 character
•Field A has 0 characters
