The system does not distinguish between uppercase and lowercase alphabetic characters in a
file name. If all the optional left-hand parts of a file name are present, it is called a fully qualified
file name; if any of the optional left-hand parts are missing, it is called a partially qualified file
name.
For more information about file names and process identifiers and the rules that govern them,
see the Guardian Procedure Calls Reference Manual.
Reserved File Names
Subvolume names and file names that begin with the letter “Z” are reserved.
Disk File Names
The syntax for a file name that identifies a disk file is:
[system.][[volume.]subvol.]filename
or
[system.][volume.]temp-filename
system
specifies the name of the system on which the file resides. A system name consists of a
backslash (\) followed by one to seven alphanumeric characters; the first alphanumeric
character must be a letter.
volume
specifies the name of the volume on which the file resides. A volume name consists of a dollar
sign ($) followed by one to six alphanumeric characters; the first alphanumeric character
must be a letter.
subvol
specifies the name of the subvolume on which the file resides. A subvolume name has one
to eight alphanumeric characters; the first character must be a letter.
filename
specifies the name of a permanent disk file. A permanent-file name consists of one to eight
alphanumeric characters, the first of which must be a letter.
temp-filename
specifies the name of a temporary disk file. A temporary-file name consists of a pound-sign
(#) followed by four to seven numeric characters. The operating system assigns names to
temporary files.
The following is an example of a fully qualified disk file name:
\hdq.$mkt.reports.finance
Nondisk Device Names
The syntax for a file name that identifies a nondisk device is:
[system.]device-name[.qualifier]
or
[system.]ldev-number
system
specifies the name of the system on which the device resides. A system name consists of a
backslash (\) followed by one to seven alphanumeric characters; the first alphanumeric
character must be a letter.
