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 :
CORE\INC\AMCOSEXE.ASHfor ASM fileslinker\amcos_linker\amcos_linker.hfor C files
