Glossary

environment. An area in which NonStop NET/MASTER MS users, NonStop
NET/MASTER MS commands, and NCL processes operate. An environment is
designed to limit the default activities of these users, commands, and processes.
environmental profile. A profile that determines what a user can do in an environment.
The user can change certain aspects of this profile by using the NonStop
NET/MASTER MS PROFILE command. An RMS ruleset can contain an
environmental profile record that a message handler can use to set up its execution
environment.
equate. A symbol defined to correspond to some text by the EQUATE command. The
text is normally one or more NonStop NET/MASTER MS commands. There are two
types of equates: local and global.
error. A condition that causes the execution of a NonStop NET/MASTER MS
command, the compilation of an NCL procedure, or the execution of an NCL process
to fail (a run-time error). In NCL, a condition caused during compilation that would
cause run-time errors if the NCL procedure were executed. A message that begins
with ERROR is displayed. Compilation continues but no object is produced. See also
compilation error, fatal error, run-time error, and warning.
error attribute. An attribute acquired by a variable used in a panel or referred to by the
SETERR operand of the ASSIGN verb.
error field. A field in a panel that displays an error message when an error is detected
by Panel Services.
error handler. A routine that traps a run-time error in an NCL process.
Event Management Service (EMS). A software facility that provides event-message
collection, logging, and distribution facilities for the operating system.
Event Management Service Process (EMSP). A virtual user that executes the EMSPROC
NCL procedure. The results of commands sent to EMSP for execution are sent to the
activity log.
event. A significant change in some condition in the system or network: for example,
events can be operational errors, changes in summary states, notifications of limits
exceeded, or requests for action.
event management services (EM) process. The application process that supports the
interface to Event Management Service (EMS), supports the EMSP virtual user and its
background processing environment, handles commands submitted to this virtual
user, and supports the system-level EMSPROC NCL procedure.
event message. In programmatic interfaces based on Subsystem Programmatic
Interface (SPI), a special kind of SPI message that describes an event occurring in the
system or network. In NonStop NET/MASTER MS, the displayed form of such a
message is shown as text. See also Subsystem Programmatic Interface.
exclusive OR (XOR). The Boolean operator that results in a value of 1 (TRUE) if one but
not both adjacent terms in an expression are true: otherwise the operator results in a
value of 0 (FALSE). See also inclusive OR (OR).
