Disk File Names
In addition to Enscribe files, FUP also supports SQL files. For more information about
using FUP with SQL files, see the File Utility Program (FUP) Reference Manual.
Disk File Names
A complete (fully qualified) disk file name is unique, and consists of four parts:
Each part is separated by a period, for example:
\WEST.$DISK1.SUBVOL2.FILENAME
A disk volume is like a file cabinet made up of drawers (subvolumes) containing folders
(files). You can name your own subvolumes and files. The node and volume can only be
named by the system manager.
A partial (partially qualified) file name is one that omits one or more of the parts.
These are partial file names:
FERN.HERST SUBVOL2.FILEA
HERST FILENAME
This is a fully qualified file name for the system \MEL:
\MEL.$GERT.FERN.HERST
Most disk files are created using application programs. For example, TEDIT creates
unstructured EDIT files (file code 101) for your text. You can create structured and
unstructured files using the FUP CREATE and TACL CREATE commands. See the
File Utility Program (FUP) Reference Manual and the TACL Reference Manual.
Subvolume Defaulting
When you give a partial file name, the TACL program fills in some of the missing parts
using your current default values for node, volume, and subvolume (see
However, TACL does not supply the subvolume name by default in some situations that
were allowed in previous releases. That is, if a volume name is immediately followed by
Part
Example
Description
Node
\WEST
Physical computer system where the file resides; begins with a
backslash (\). All systems must be named. You can omit the
node name if the file resides on the current default system.
Volume
$DISK1
Physical disk volume where the file resides; begins with a
dollar sign ($), followed by one to seven alphanumeric
characters. The character following the dollar sign must be a
letter. (Users on remote nodes cannot identify volume names on
your node that have more than six characters after the $.)
Subvolume
SUBVOL2
Set of files in the same disk volume; contains from one to either
alphanumeric characters and must begin with a letter.
File
Identifier
FILE3
Individual file; contains from one to eight alphanumeric
characters and must begin with a letter.
