Aucb.565 fa.editor-p utcsrgv!utzoo!decvax!ucbvax!C70:editor-people Mon Mar 1 15:29:40 1982 Concurrent File Access >From Schoen@SUMEX-AIM Mon Mar 1 15:27:03 1982 Tenex does indeed prohibit multiple writers of the same file (unless in thawed mode -- same as Tops-20). The problem with opening the source file read/write is that unless you are a wheel (we're talking Tenex/Tops-20 specifically now), the operating system updates the file's write date for you. This may be undesirable when trying to maintain a history of source changes with corresponding write dates of old versions of files.
