I have not expressed myself clearly, I have buffers that come from database, and are not associated to the file within Emacs context. Within program they are associated with the file with specific extension. vcfiles_filename entry may be "/home/admin/new.scm" and buffer name becomes something like: RCD VC Revision ID: 12, /home/admin/new.scm so buffer is not really associated within Emacs context to file name, within program's context it is directly associated. Now when I entered the sphere of auto mode settings I can see that for buffers that function is missing, or is not there. Am I right? set-auto-mode function does not verify anything for buffers how I see it. Maybe it would be better to have something for buffers not associated to files. Right now I am doing that trick to associate the file to buffer and then set auto mode, and then I can disassociate file from buffer. I am then associating the above example with /home/admin/RCD-VC-Revision-ID-12-new.scm as that way it becomes unique file. So it is solved on my side. But I still think that auto mode should also work in buffers without file, at least when user enables it. Jean
