ENABLE User's Guide

PREFACE

This guide describes how to use ENABLE, a product that is part of

the ENCOMPASS distributed data base management system provided by

TANDEM, to build simple transaction processing applications.

To use this guide, you must understand your information needs,

have a working knowledge of the Tandem text editor, and be

familiar with some data management application programs. As an

ENABLE user, you need not know the SCREEN COBOL or COBOL

programming languages.

The guide is organized in a sequence that parallels the

development of an ENABLE application:

• Section 1 introduces the capabilities and uses of ENABLE and

identifies its components.

• Section 2 provides an overview of the steps required to produce

an application. This section also introduces some concepts

referred to throughout the remainder of the guide.

• Section 3 provides guidelines for developing, describing, and

creating a data base.

• Section 4 describes the tasks you must perform to develop an

application that can access a single data base file.

• Section 5 describes the tasks you must perform to develop an

application that can access more than one data base file.

• Section 6 describes methods you can use to tailor an ENABLE

application.

• Section 7 provides guidelines for modifying the SCREEN COBOL

source code generated by ENABLE

• Section 8 provides guidelines for using an ENABLE application.
