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.

only 1 chapter, having 120 pages) the image address has been
defined:
Field D has 2 characters
Field C has 1 characters
