VAX 9000 Family Console Command Description

This document, the "VAX 9000 Family Console Command Description," is a technical manual detailing the commands implemented by the VAX 9000 family Service Processor Unit (SPU), commonly known as the console, when operating in console I/O (CIO) mode.

It is intended for system operators, Digital Customer Services personnel, and other console interface users, assuming familiarity with the VAX 9000 family architecture and the Digital Command Language (DCL).

The manual is structured into chapters covering:

• Console Command Language: Explains the syntax, command qualifiers, special and user-defined keys, message format, numerical radix, expressions, and data types.
• Console Command Descriptions: Provides detailed information on a comprehensive set of console commands, including those for allocating/deallocating resources, booting, file and directory management (e.g., COPY, CREATE, DELETE, DIRECTORY), debugging, system configuration (e.g., SET, SHOW), and system control (e.g., RUN, HALT, MICROSTEP, SENSE, VERIFY).
• Lexical Function Description: Describes functions that return numeric or string results, used for tasks like extracting substrings, parsing file names, or retrieving information about system components (e.g., CPU, Memory, Clock).

Appendices provide quick references for both commands and lexical functions.
