Two level offset indexing
When using two 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.
•Fields C, B and A may be defined as fixed fields if desired.
For example, if you scan a book with 2 chapters (Chapter 1 has 40 pages and Chapter 2 has 60 pages), the image address has been defined:
•Field D has 2 characters
•Field C has 0 characters
•Field B has 0 characters
•Field D has 0 characters
