File Name Expansion
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 Pathway environment
is running on this system, only $TAPE1 is required for the file name.
File Name Expansion
File name expansion is accomplished through the use of default names. If you omit
the node, volume, or subvolume name in a command parameter, PATHCOM uses
system defaults to expand the file name before passing the name to the PATHMON
process.
To get the default for the node name, PATHCOM first determines whether the SET
PATHWAY NODEINDEPENDENT attribute is set to ON. If NODEINDEPENDENT is
ON, the default node name is \* , a generic name representing the node where the
PATHMON process is currently running. For information on configuring for the node
independence, see Specifying Node Independence on page 3-6 and SET PATHWAY
Command on page 11-12.
If the SET PATHWAY NODEINDEPENDENT attribute is set to OFF, PATHCOM uses
the node name you supply in the CMDVOL command. PATHCOM also uses the
default volume and subvolume names specified in the CMDVOL command. For
information on the CMDVOL command, see CMDVOL Command on page 10-3.
Although the PATHMON process uses system names, it does not store server process
names (nor Pathway/iTS TCP names) in fully qualified network form. All other file
names are kept in the form:
\node.$volume.subvolume.file–identifier
OSS Pathnames
An OSS pathname in the OSS attributes PROGRAM, STDIN, STDERR, and STDOUT
can be an absolute pathname or a relative pathname. Case is significant.
When specifying an OSS pathname longer than one line, use the PATHCOM
continuation character (&) at the end of the line to indicate continuous input. If the
pathname includes an ampersand (&) as part of the name and the ampersand occurs
at the end of an input line, enter two ampersands. An ampersand occurring in the
middle of an input line, embedded in a pathname, need not be doubled. To embed
blanks, quotes, commas, and semicolons, use the same rules as for PATHCOM; in
other words, enclose the entire pathname in quotes.
Absolute Pathnames
Absolute pathnames must begin with a forward slash (/) and can have a maximum
length of 1023 characters; the last character (character 1024) is reserved for a null.
