Self-Defining section1

The Self-Defining section consists of a set of triplet fields used to locate the various sections within the record.

The first field of each triplet is the offset from the beginning of the record (field SMFJOxxO) to the start of the section.
The second field (SMFJOxxL) contains the length of the section.
The third field (SMFJO xxN) contains the number of contiguous sections present of the particular type.

A nonzero value in the number field indicates that the section exists in the record. A zero value indicates that the section does not exist in the record.

The Self-Defining section field descriptions are shown in the following table.
