In POSIX systems like Linux DOS DENY flags (EXCLUSIVE mode) do not exist. DOSEMU emulates them only and such emulation is visible and respected only by programs executed in DOSEMU. The exception is when inside DOSEMU you are running network client which connects to file server directly instead of using LREDIR volumes. In such case DOSEMU sends information about the DOS DENY flags to file server which can manage them and synchronize other clients. > The second test, on my computer I use the file exclusively under > foxpro (on dosemu).

You are simply making sth what cannot work with programs executed outside DOSEMU. best regards, Przemek _______________________________________________ Harbour-users mailing list (attachment size limit: 40KB) [email protected] http://lists.harbour-project.org/mailman/listinfo/harbour-users
