    13 The program that will permanently convert binaries (EXE and DLL files) is called PE2LX.EXE. However, it's much more flexible to use dynamic, on-the-fly conversion (via PE.EXE loader)  because in that case executable modules on disk are not changed, and you can use your Win32 programs in both Windows and eCS (OS/2) from the same space on disk. ''Both methods can be automated and made absolutely transparent to users with the use of the WIN32K.SYS driver that allows OS/2 processes (WPS, command prompt...) to launch Win32 binaries as any other OS/2 applications, providing automatic conversion/loading at startup time.'' '''NOTE: The WIN32K.SYS approach is not building anymore with Odin 0.8 and up.  WIN32K.SYS from prior to 0.8 seem to work at this time (0.8.5)'''

    1515Converted/loaded program will look and behave as any other eCS (OS/2) application. There is no emulation layer, no Windows "sessions" or virtual machines like it was the case with Win-OS/2 that IBM has provided for running Windows 3.1 applications: the code is executed directly by CPU with all rights, privileges and limitations of normal 32-bit eCS (OS/2) programs. In order for program to operate, it must have access to the same API functions as in Windows operating system(s). Those functions are called Win32 API (Application Programming Interface) and Odin provides them, as well. It's the second part of the project which aims at: Providing runtime libraries that replicate Win32 API functions and that are used by loaded and running programs. Runtime libraries are supplied as a number of DLL files with the same names as the ones what are supplied with Windows because Win32 applications expect to find them under those names. Any name conflicts (DLLs with same names shipped with eCS (OS/2)) are resolved during the conversion/loading process. Odin32 DLLs are pure native eCS (OS/2) binaries which operate in the same way as their Windows counterparts. The set of API functions that are implemented for Project Odin is called Odin32.
