This guide provides complete directions for searching the Computerized Task Inventory (COMTASK) database or for adding information to or modifying information in the database. (The COMTASK database contains information about jobs and the duties, tasks, and equipment needed to perform each job.) Chapter I describes the guide, its purpose, and the updating procedures. Chapter II provides a history and description of COMTASK, covers the types of information currently available from COMTASK, and indicates future directions COMTASK will take with a brief description of the type of information needed to make the database viable and useful. The steps to be taken to begin or end a search or other computer connection with COMTASK are found in chapter III. Chapter IV contains directions for directing a search. Examples of several menus are displayed, with detailed explanations of alternatives. Chapter V describes procedures for adding information to COMTASK. Chapter VI explains how to access "HELP" menus that are found in each menu. Chapter VII describes options for displaying search results. Chapter VIII covers problems that may be encountered when using the database, possible causes, and solutions. A COMTASK Database Tree Chart and an explanation of "union,""intersection," and "minus" are appended. (YLB)
