On the one hand, it contains, starting on address 0018, a sequence of a «LListB» and a «LListE». The «LListB» contains the bulk data, the «LListE» contains 5 byte elements with offsets, relative to address 001E, in each last long where all sections start.On the other hand, at address 001E a list of sections start. Each section starts with a word encoding the length of the section.
