How does using WM_MOTIF compare to using a Windows emulation such as SoftWindows or DOS Merge ?
One of the advantages of running a native Motif application over a DOS emulation layer is that the resource requirements are much smaller. Merge gives a virtual DOS session to every user so you basically reload most of DOS, Windows and your application for every user. Normally one complaint of people using DOS Merge (not just for OWL applications but for any DOS app) is that they drain memory very quickly; when the OS starts swapping performance goes down significantly. A native Motif application generally has shared text executables so the first user loads the text portion of the executable which is then shared by all subsequent users. Another advantage of having native applications is that you have full access to all the OS resources. This is important if your application takes advantage of networking or client/server functionality. Shared memory or sockets are not available directly to DOS sessions. You also don’t have to deal with mangled file names (e.g. SCO UNIX allows long file
