==Introduction==
The AMCX file format is used for all executable files used in AMC-OS, including kernel itself. They are equivalent to PE for DOS/Windows, ELF for Unix and so on.

Linking of object files to build an AMCX file is done by the [[AMC-OS Linker]].

==API==

To manipulate AMCX files, structures are defined in :
* <code>INC\AMCOSEXE.ASH</code> for ASM files
* <code>linker\amcos_linker\amcos_linker.h</code> for C files
