NET/MASTER Network Control Language (NCL) Reference Manual

About This Manual
106126 Tandem Computers Incorporated xxiii
Network Control Language (NCL) is a structured, high-level language, supplied with
NonStop NET/MASTER Management Services (MS). NCL is a comprehensive and
advanced development tool that can be used to implement the specific requirements of
your installation.
The NonStop NET/MASTER NCL Reference Manual is designed to give you a complete
description of NCL constructs. This manual should be used in conjunction with the
NonStop NET/MASTER NCL Programmer's Guide.
This manual provides a complete summary of the various features of the NCL
programming language.
Who Should Read This
Manual
This manual is intended for all NonStop NET/MASTER MS users who write and
maintain NCL procedures. This includes programmers, operators, system managers,
and network managers.
What You Need to
Know Before Using
This Manual
If you are going to write in NCL, you need to know the following:
How to use the terminal or workstation from which you use NonStop
NET/MASTER MS.
How to use NonStop NET/MASTER MS, particularly Operator Control Services
(OCS) and Edit Services.
How to use the Tandem text editor, PS Text Edit (TEDIT).
If you know another programming language, such as C or Pascal, you will find that
many NCL concepts and terms are familiar.
How This Manual Is
Organized
This manual contains 11 sections, a glossary, and an index. An overview of each
section follows:
Section 1, “Introduction to NCL,” introduces NCL. It explains where NCL fits in
with major NonStop NET/MASTER MS services and describes some of the
operations available through NCL.
Section 2, “Core Statements,” lists and describes each core statement in alphabetic
order, with syntax, considerations, and examples. Core statements cause action to
occur; most core statements affect the structure and flow of NCL process
execution.
Section 3, “Verbs,” lists and describes each verb in alphabetic order, with syntax,
considerations, and examples. Verbs cause action to occur, but do not affect the
structure and flow of NCL process execution.
Section 4, “Built-in Functions,” lists and describes each built-in function in
alphabetic order, with syntax, considerations, and examples. Built-in functions
provide access to information that could otherwise require extensive coding to
acquire.
