Function Calls
file name. If, however, you specify a volume name, you must specify a subvolume
name. This file name is not syntactically correct:
$VOLUME.FILE
If you specify a partial file name, TACL expands the file name using the current
default names for system, volume, and subvolume where necessary. If you specify
MYFILE, for example, TACL assumes you mean the file named MYFILE in the
current default subvolume, volume, and system.
For more information about file-name expansion, see the Guardian User’s Guide.
•
Many built-in functions accept file-name templates in place of actual file names, so
that the command or function can operate on a number of similarly named files.
For information about file-name template characters, see Section 2, Lexical
Elements.
Device-Name Arguments
TACL evaluates a device name based on what you specify and what the current
defaults are. For file-name arguments, if you do not specify a node name, then TACL
uses the current default system.
Process Identifier Arguments
A process identifier identifies a process within a system or in a network. TACL uses
these types of process identifiers:
•
Process name
A process name identifies a process or process pair within a node. The name is an
alphanumeric string up to five characters long, preceded by a dollar sign, and can
be preceded by a node name. The first character must be alphabetic. TACL uses
process names in displays and interactive requests. For each named process or
process pair, the format is $ process-name; for example:
$ABC
\SYSTEM.$PRC12
The D-series process name is similar to a C-series process name, but a five-
character name is allowed for remote processes. (The syntax for D-series remote
process names matches the syntax for local names.)
TACL evaluates process names based on what you specify and what the current
defaults are. If you do not specify a node name, then TACL uses the current
default system.
•
CPU,PIN (also known as a PID)
The combination of a CPU number and process identification number (PIN) identify
a process on a node. This combination is the only way to identify an unnamed
process on C series or earlier software.
