Object File Format
Object File Format
All object files have the same format, regardless of the number of code and data
blocks.
Figure 4-1 shows an example object file made up of several blocks copied from
different object files. For additional information on mixed-language binding, see Binding
Mixed-Language Programs on page 2-13.
On disk, an object file can consist of a maximum of 16 extents. The header, code, and
data areas must be in the first extent (0). You can use the additional extents (1 through
15) for Inspect symbol tables and Binder tables.
