Odin (known before as Win32-OS/2) is a project to run Microsoft Windows programs on OS/2 or convert them to OS/2 native format.

The project's goals are: Although this is far from complete, much of the Win32 API is not widely used, so partial implementation will give usable results.

[3][4] Odin achieves binary compatibility by converting Win32 executables and dynamic-link libraries to OS/2 format.

Conversion can be done on the fly (each time the application is run) or permanently.

Odin uses code from Wine, which runs Win32 applications on Unix-like operating systems.
