HP Tandem Advanced Command Language (TACL)
HP Tandem Advanced Command Language (TACL). The user interface to the NonStop
OS. The TACL product is both a command interpreter and a command language.
Users can write TACL programs that perform complex tasks or provide a consistent
user interface across independently programmed applications.
inbound queue. The inbound queue is used to hold message descriptors for data received
from the LAN.
input source. The resource from which Subsystem Control Facility (SCF) accepts
command input. SCF can accept input from a terminal or a disk file. The initial input
source is determined by the form of the RUN command used to initiate SCF. At any
time during an SCF session, the input source can be temporarily changed to execute a
series of commands from a command file.
input/output process (IOP). A running program (part of the NonStop OS) that manages the
I/O functions for one or more ServerNet addressable controllers (SACs) of the same
type.
interactive mode. A mode of operation that is characterized by having the same input and
output device (a terminal or a process) for the session. If a terminal is used, a person
enters a command and presses Return. If a process is used, the system interface waits
for the process to send a request and treats the process in the same manner as a
terminal. Contrast with noninteractive mode.
IOP. See input/output process (IOP).
IOperm. A space in flat segment memory to provide an aliased memory space.
kilobyte (KB). A unit of measurement equal to 1024 bytes. See also gigabyte (GB),
megabyte (MB) and terabyte (TB).
Kseg2. The part of virtual memory that provides addressing for the absolute memory
allocations.
LAN. See local area network (LAN).
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. One or more LANs can be connected to the
system such that the LAN users can access the system as if their workstations were
connected directly to it. Contrast with wide area network (WAN)
.
MAC address. See media access control (MAC) address
.
management process. A process through which an application issues commands to a
subsystem. A management process can be part of a subsystem, or it can be
associated with more than one subsystem. In the latter case, the management process
is logically part of each subsystem. Subsystem Control Point (SCP) is the management
process for all subsystems controlled by Subsystem Control Facility (SCF).
