When you need the information supplied, read through the relevant chapters in full. You can later return to read selected parts as reference. The chapters in this guide are: Chapter 1, Introduction An introduction to the guide Chapter 2, Developing COBOL Applications A description of how to develop COBOL applications using this COBOL system. Chapter 3, Writing Programs This chapter covers various aspects of how this system affects programming in COBOL. It principally deals with creation of efficient programs, but also looks at the best ways to handle large programs. Chapter 4, The COBOL Interfacing Environment An explanation of the interfacing facilities provided in this system. Chapter 5, Mixed-language Programming An explanation of how to use the interfacing facilities to mix COBOL programs with programs or subprograms in other languages. Chapter 6, Multi-user File Handling (Generic) If you wish to create applications that allow multiple users to share files, then this chapter explains the facilities available in this system and how to use them. Chapter 7, SQL Database Interface (Generic) This COBOL system has facilities that allow you to use SQL statements in your COBOL program to access databases via IBM Database Manager or Microsoft SQL Server. Chapter 8, Comparison of Screen Handling Methods (Generic) There are many ways of accessing the screen and keyboard to interface with the user. This chapter discusses the relative merits of each method available in this system. Chapter 9, Motif Applications The features in this COBOL system enable you to create applications that use the facilities of OSF/Motif to give your application a graphical user interface (GUI). This chapter explains how to use these features. Chapter 10, Portability Issues (Generic) This chapter explains the issues in making your applications portable between environments supported by Micro Focus COBOL. The appendices in this guide are: Appendix A, National Language Support Demonstration (Generic) This appendix provides a demonstration of the National Language Support. Appendix B, Your Environment (Generic) This appendix helps you if you are writing a program that uses environment specific facilities, for example, operating system support routines.
