Parts of a Disk File Name
•
Can contain ASCII characters only
•
Are not case-sensitive; the following names are equivalent:
myfile
MyFile
MYFILE
Language functions and system procedures that return file names might return
them in uppercase (even if the file name was originally in lowercase). Check the
description of the function or procedure that you are using.
Parts of a Disk File Name
A disk file has a unique file name that consists of four parts, with each part separated
by a period:
•
A node name
•
A volume name
•
A subvolume name
•
A file ID
Here is an example of a disk file name:
\mynode.$myvol.mysubvol.myfile
You can name your own subvolumes and file IDs, but nodes (systems) and volumes
are named by the system manager.
All parts of the file name except the file ID are optional except as noted in the following
discussion. If you omit any part of the file name, the system uses values as described
in Partial File Names on page 7-3, later in this section.
Node or System Name
The node or system name, such as \MYNODE, is the name of the node or system
where the file resides. If specified, the node or system name must begin with a
backslash (\) followed by one to seven alphanumeric characters. The character
following the backslash must be an alphabetic character.
Volume Name
The volume name, such as $MYVOL, is the name of the disk volume where the file
resides. If specified, the volume name must begin with a dollar sign ($), followed by
one to six or one to seven alphanumeric characters as follows. The character following
the dollar sign must be an alphabetic character.
The volume name can contain one to seven alphanumeric characters.
