Reading the self-defining section for same-length data items
If the length of each item in a
data section is the same, the self-defining section indicates the length in
a halfword that follows the fullword offset. If this value is 0, the
length of the data items varies.
The relationship between the contents of the self-defining section “pointers”
and the items in a data section for same-length data items is shown in The
figure below.Figure 1. Relationship between self-defining section and data sections for same-length data items
