File Name Expansion
File names of disk files are represented to programs on HP NonStop systems by these
four parts concatenated into a contiguous string. Each part is separated from the other
by a period as follows:
\node.$volume.subvolume.file–identifier
When you supply only a partial file name as a command parameter, the internal
representation of the file name is expanded into the full four-part file name. As a
minimum, a partial file name must consist of the file identifier.
Each process and each device, such as a tape drive or printer, is identified the same
way a disk file is identified. For example:
\TSB.$TAPE1
specifies a particular tape drive on the system named \TSB. If a PATHMON
environment is running on this system, only $TAPE1 is required for the file name.
File Name Expansion
A command interpreter for a terminal has associated with it a default volume name and
a default subvolume name. File name expansion is accomplished through the use of
these default names. If you omit the volume name, the default volume name is used in
its place.
Although the PATHMON process uses system names, it does not store TCP names in
fully qualified network form. All other file names are kept in the form:
\node.$volume.subvolume.file–identifier
PATHCOM uses the name that you supply in the CMDVOL command to expand a
process file name before passing the process name to the PATHMON process.
