Two level offset indexing
When using two level offset indexing, the image address assigned to
each document is defined as follows:
• Field A (Level 1) is defined as having a field length of 0
• Field B (Level 2) is defined as having a field length greater than 0
• Field C (Level 3) is defined as having a field length of 0
• Fixed field may be defined, 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 A has 0 characters
• Field B has 2 characters
• Field C has 0 characters
• Fixed field has 0 characters

remaining pages of Chapter 2 are also assigned image address 02.
Either one of the chapter header pages may later be located and

manually scrolling through the remaining pages of the chapter.
