Interactive Query Language Users Guide Dec78

This document is the Interactive Query Language (IQL) User's Guide, Release 3.0, published in December 1978 for Digital Equipment Corporation's TOPS-10 and TOPS-20 operating systems.

It serves as a detailed reference manual for IQL, a comprehensive data management system. IQL provides capabilities for defining, inputting, updating, browsing data files and databases, retrieving information, and generating sophisticated reports.

The guide is intended for users already familiar with DBMS schemas and IQL's basic FIND and GET operations, and is not an introductory manual. It covers:

• IQL functions and file handling.
• Running IQL, including command levels, prompts, and message formats.
• Creating and editing queries to generate reports.
• Creating, updating, and reading data files.
• Defining and managing dictionaries (targeted at database administrators and programmers).
• Executing IQL in batch jobs (also for DBAs and programmers).

It specifies IQL Release 3.0 as requiring DBMS Version 5+, COBOL Version 12+, and SORT Version 3.0+ (TOPS-10) or 4.0+ (TOPS-20).
