Glossary

communications network management (CNM). An IBM architecture that describes the
structure of messages traveling to and from SNA devices.
compilation. The process of creating object code from a source file of NCL statements.
compilation error. An error in an NCL procedure detected during compilation (before
execution). There are three types of compilation errors: from least to most severe
these are warnings, errors, and fatal errors. See also error, fatal error, run-time error,
and warning.
compiler. The NonStop NET/MASTER MS preprocessor that creates an object file from
a source file when an NCL procedure is invoked.
compiler directive. An NCL statement that begins with two percent signs (%%) and is
used to control the compiler during the compilation of an NCL procedure.
complex variable. A variable that contains more than one ampersand (&).
compound variable. A variable that contains segments (substems) between periods (.).
condition handler. A routine that traps a specified condition detected by an NCL
process.
condition name. The name of a specified condition that causes a block of NCL
statements to be executed when the condition occurs. The condition can be an error
condition. The block of NCL statements that is executed is referred to as an ON block
or condition handler.
CONFIG file. See configuration file.
configuration file. Sometimes called a CONFIG file, an edit file containing PARAM
commands that set the startup parameters.
Console Extras. A NonStop NET/MASTER MS service that allows a user to access
external Guardian utilities.
context. The setting in which a lexical element becomes meaningful within an NCL
statement.
control character. A character whose occurrence in a particular context initiates,
modifies, or stops an operation. In NCL, control characters are illegal.
control environment. The current settings of the CONTROL verb during the execution of
an NCL process.
control options. The RMS options that set up the basic operational criteria for the rules
in a ruleset. A ruleset always contains a control options record.
control part. The part of a panel description file containing panel control statements.
Conversational Interface Process (CIP). The process with which NonStop NET/MASTER
MS communicates to handle Distributed Systems Network Management (DSNM)
utility commands.
core statement. An intrinsic part of NCL. Its availability does not depend on the
enabling of a NonStop NET/MASTER MS feature.
