Welcome to OpenVMS.

Probably the same way you do on Unix.

There are links there to the OpenVMS FAQ, the Freeware CD-ROM,
and the documentation.

You can also use the HELP command.

There are three interactive editors supplied with OpenVMS, and many of 
editors like vi and emacs are available off of the web.

Or you can take an easy way, ftp the file over to your UNIX system, 
modify it and FTP it back.  Just make sure you transfer it as ASCII, not 
binary.  It makes a big difference on OpenVMS.

Please, when posting questions, the version of SAMBA for OpenVMS, the 
version of OpenVMS, which of the several TCP/IP programs and it's 
version.  VAX or Alpha (and IPF when available) can also be important.

SAMBA 1.19.x may have a problem with using concealed logical names in 
it's configuration file.

I do not know if SAMBA 2.0.3 also has that problem.

SAMBA 2.0.6 prefers that concealed logical names are used.  Concealed 
logical names are a prefered method of referencing logical volumes on 

On OpenVMS, file specifications are of the format:


But programs like SAMBA that are written in C can usually accept, and 
SAMBA basically requires this format:


Where device is either a physical device like DKA0:, or a logical device 
like SAMBA_ROOT:.  Logical devices are preferred, because then you do 
not have to edit your configuration files if you change what physical 
disks that you have.

The [DIR.DIR] can have up to 8 directories separated by periods, for 
versions of OpenVMS prior to 7.2.  After that, deeper directories are 
allowed, see below, and the HELP SPECIFIY command.

The file.ext is the name of the file.

The version is a number from 1 to 32767.

OpenVMS is not case sensitive.

On VAX only the ODS-2 file system is available.
On ALPHA above version 7.2, the ODS-5 file system can also be configured.

ODS-2 is limited to 39 character directory or filenames, with a 39 
character extension.  Total file specifications are limited to 255 

Both file systems are not case sensitive.

ODS-5 is case preserving, and can handle most special characters, but 
some of the special characters may cause SAMBA problems.

ODS-5 is a newer file system for OpenVMS, and there may be issues with 
it and SAMBA.

The root directory for a physical or logical device is [000000].  For a 
logical device it does not really exist.  If you are referencing file 
foo.dat in the root directory then you use [000000]foo.dat.

But using the file specification []foo.dat would be the same 
thing as specifying "./././bar/foo.dat" on UNIX.
