message-oriented requester
same kinds of services that system managers can request through the PATHCOM
interface. A management application can also interact with subsystems other than the
Pathway subsystem. Management applications use the Subsystem Programmatic
Interface (SPI) to send commands to subsystems and the Event Management Service
(EMS) to receive notification of significant events.
message-oriented requester. A SCREEN COBOL requester that sends data from working
storage to a device (or to a front-end process that controls a device) and receives data
from the device or process into working storage by way of Message Section templates.
SCREEN COBOL requesters that use the intelligent device support (IDS) facility are
message-oriented. These requesters use SEND MESSAGE statements and their
REPLY clauses in the Procedure Division to interact with the intelligent devices or
front-end processes. See also screen-oriented requester.
Message Section. A section in the Data Division of a SCREEN COBOL source program
that describes the data type, size, and relative position (sequence) of each field in a
message template. This section also defines the editing and conversion that must be
performed on each field. See also message-oriented requester.
mixed data item. A data item that contains both single-byte and double-byte characters; in
a COBOL or SCREEN COBOL program, these data items are declared as PIC X.
modified data tag (MDT). In SCREEN COBOL, a bit that is set or reset to indicate whether
data in an associated field is to be sent to the computer from the terminal.
multithreaded. A programming model that provides more than one thread of control within
a program. Multithreading allows multiple sequential processing tasks to be executed
concurrently within a process: for example, a terminal control process (TCP). See also
thread and single-threaded.
native System/T client. In the NonStop TUXEDO environment, a client program that
executes in the Open System Services (OSS) environment and communicates directly
with System/T. An example of this type of client is the Pathway translation server for
the NonStop TUXEDO system. Also called a NonStop TUXEDO native client.
nested server. A server that acts as a requester by sending requests to other servers.
In the Pathway environment, such requests are made by calls to Pathsend procedures.
nld utility. A utility that collects, links, and modifies code and data blocks from one or more
object files to produce a target TNS/R native object file.
node. A Tandem NonStop system that is part of an Expand network. The name of the node,
also called the system name, is the first of four parts of a file name in the Guardian
environment. See also Expand networking software.
no-early-reply rule. The rule that states that when a server process reads a request
message, it should completely process the request before it replies to it.
