A TNS/E Native Object Files
This appendix contains the following information:
The Object File Format - the types of object files and their content.
Code and Data Sections - the "ordinary" code and data sections that come from
application source code, possibly with additions by the compiler or linker.
Relocation Tables - when code is relocated, who resolves the address and prepares
relocation tables?
The DWARF Symbol Table - this table contains information used by debuggers and the
Cobol compiler.
Archives - contains an extension of material covered in a previous section of this
manual.
Tools That Work With Object Files - a quick look at which NSK tools use object files.
The Object File Format
This general information may also be found in the eld Manual.
Basic Properties of Object Files
User versions of TNS/E tools may run in the following places:

All TNS/E versions of the NSK operating system, including both the Guardian
and OSS “personalities” of NSK.

Some TNS/R versions of the NSK operating system, at least in the Guardian
personality.

Appropriate versions of the Windows operating system on PC’s.
TNS/E object files only run on TNS/E.
On Guardian, and in Guardian subvolumes of OSS, object files are unstructured files
that are “odd unstructured”, the same as in TNS/R.
On Guardian, and in Guardian subvolumes of OSS, TNS/E object files have the file
code 800.
TNS/E object files use the 64-bit version of the ELF file format.
TNS/E object files are big endian. This means that all their data is big endian. Code
on the IPF (Itanium Processor Family) platform is always little endian.
Types of TNS/E Object Files
There are the following four types of TNS/E object files.
