Copyright 1987-1993 by Micro Focus Ltd. All rights Reserved. Printed in U.S.A. Printed October 1995 Preface Micro Focus COBOL is a system for developing and running COBOL programs. This manual describes operating procedures for the UNIX resident releases of the Micro Focus COBOL system. Audience It is assumed that you are familiar with the COBOL language. Additionally, some experience of the UNIX operating system is desirable. To get the most out of the information in this Reference, you already should have read the Getting Started book included with this product and installed the software. Additionally, you should have familiarized yourself with the basics of the COBOL development cycle as described in the COBOL User Guide provided with this product. Related Publications Other manuals in the Micro Focus COBOL document set are: * Getting Started * Language Reference * Language Reference - Additional Topics * Error Messages * COBOL User Guide * Compatibility Guide * Pocket Guide Notation In This Manual * Enter refers to the carriage return or Enter key. Where commands to be typed are shown, the Enter key is not explicitly shown; it is treated as implicit that the Enter key must be pressed at the end of the line. * F1=Help is not described in the documentation. Help is context sensitive and appears on each menu in the system. * Hexadecimal numbers are enclosed in quotation marks and preceded by a lower case x or lower case h; for example, x"9D". The h is used when the number represents a number rather than a string of characters. Command Lines The notation used to describe the format of command lines is as follows: * Words printed in italics are generic terms representing names to be devised by you. * Words printed in nonitalic characters are the actual words you must enter. * Material enclosed in square brackets [ ] is optional. * When material is enclosed in braces { }, you must choose from the options within them. If there is only one option in the braces, the braces indicate repetition. * The ellipsis (...) follows { } or [ ] and means you can repeat the material in the { } or [ ]. The number of repetitions allowed is unlimited unless otherwise stated. If the ellipsis is used with [ ] the material can be omitted altogether. * If a command line will not fit across the page, it is continued on the next line; the continuation line is indented. Environments Some of the chapters in this book are common (generic) between this COBOL system and Micro Focus COBOL for DOS, Windows and OS/2. Where text does not apply to all the environments, the environments that it does apply to are specified in parentheses follow This text applies only to the UNIX system. (UNIX) The generic chapters are identified in chapter 1 of this guide. All other chapters are specific to this COBOL system on UNIX. * UNIX is case-sensitive, so if you are using UNIX you must type commands in the case shown in the book. DOS, OS/2 and Windows are not case-sensitive, so on these operating systems you can type them in upper, lower, or mixed case as you wish. DOS, Windows and OS/2 Considerations * The term "OS/2" refers to both Microsoft Operating System/2 (MS OS/2) and IBM OS/2. Similarly, the term "DOS" refers to both IBM Personal Computer DOS and MS-DOS. * The term "window" means a delineated rectangular area on the screen, normally smaller than the full screen. The term "Windows" means Microsoft Windows 3.0 or later. UNIX Considerations * The term "UNIX" can be taken to mean all operating systems that are compatible with UNIX System V, Release 3.0 or later, complying with the System V Interface Definition (SVID). * The commands given in this manual are specifically for the Unix operating system. For other similar operating systems, see your Release Notes for the commands to use. You may also be referred to the Release Notes for other operating system specific details. * All command line formats and examples are for the standard Unix shell, the Bourne shell. If you are using another shell, see your Unix documentation for the appropriate formats. * Where examples showing environment variables do not specifically show them being exported to the shell, it is treated as implicit that the environment variables are exported. * The keys described in this documentation are not available on all environments. References to pressing keys such as function or status keys imply the logical pressing and releasing of these keys rather than the physical keystrokes. A chart listing how your actual keystrokes map onto the keys shown in the document * You may notice that what appears on your screen sometimes differs in minor ways (for example, version numbers) from that illustrated in the manuals. This will not affect the operation of your software.
