This guide describes how to migrate applications from other COBOL systems to run with this COBOL system. The final part of this guide provides lists for each dialect convering the features supported by this sytem, historical details of when the support was first provided and the compiler directives required for compatibility. This COBOL system supports the COBOL language described in your Language Reference. Audience The aim of this Guide is to enable you to migrate from any of the environments: * IBM OS/VS COBOL * IBM VS COBOL II * Microsoft COBOL v2.2 * RM/COBOL * DG Interactive COBOL to this COBOL environment. It is intended to be used by users who either want to: * convert applications written in the selected COBOL language to the Micro Focus COBOL language, and to enhance them using the advanced language and development features offered by this COBOL system, or: * retain the use of the selected COBOL on some machine environments while moving to this COBOL environment on others. If you fall into this category you will want to maintain a common set of source programs which are suitable for all environments. * convert the selected COBOL formatted files to the file format used with this system. It is assumed that you are familiar with the COBOL language, and have access to the documents listed in the section Related Publications below. Related Publications This manual is designed to be used in conjunction with the following manuals which are also supplied with your system: * Language Reference * COBOL System Reference * Error Messages For Conversion Series 5, you must also have access to revision 2 of The Data General Interactive COBOL Programmer's Reference Manual. Notation in this Manual * Throughout this manual the Micro Focus COBOL language is referred to as the MF COBOL language. * When items are enclosed in brace { }, you may choose one and only one of the items in the braces. * When items are enclosed in square [ ], you may choose one of the items in the brackets or none of the items. * Running headers contain the title of the chapter and the running footer contains the title of the publication. * The page number is composed of two numbers: the first is the chapter number and the second is the page within the chapter. * Throughout this manual, system directives and their parameters are shown in the following format: DIRECTIVE (PARAMETER) Note that, if using a UNIX based system, you must enclose the entire parameter string within quotation marks, for example: "NOMF RM(ANSI) REMOVE(COL)" See your COBOL Reference for details of the format of directives applicable to your system. About this Manual This manual is split into a number of parts. Each part covers particular areas of compatibiltiy. Part I - Conversion Series 1 - IBM/370 Mainframe Compatibility This part describes how you can configure your COBOL system to allow you to process IBM/370 programs (that is, programs written in IBM VS COBOL II and OS/VS COBOL) directly. It also lists known incompatibilities that you may encounter when migrating IBM/370 mainframe programs to this COBOL system. Part II - Conversion Series 2 - Microsoft COBOL V2.2 This part describes how you can configure your COBOL system to allow you to process Microsoft COBOL Version 2.2 programs directly. It also lists know problems you may encounter when you use your Microsoft COBOL Version 2.2 programs on this COBOL system. Included in this part is a description of the REBUILD utility which, when invoked, will enable you to convert files from the Microsoft COBOL Version 2.2 format to this COBOL format. Part III - Conversion Series 3 - RM/COBOL V2. This part details how you can use this COBOL system to process Version 2 RM/COBOL source programs directly. This part also describes the convert 3 files conversion utility, which converts data files created by RM/COBOL programs into data files that can be accessed by the same programs under this COBOL system. Part IV - Conversion Series 5 - DG Interactive COBOL This part details how you can use this COBOL system to process DG Interactive COBOL source programs directly. This COBOL system supports the Micro Focus COBOL language. This part also describes the use of a pair of utilities: * reform5, which reformats a DG Interactive COBOL source code program so it can be submitted to this COBOL system. * convert5, which converts data files created by DG Interactive COBOL programs into data files that can be accessed by the same programs once they have been reformatted to the datafile format used with this COBOL system. Part V - Dialect Summary The COBOL system that this part reflects provides support for many dialects of COBOL. This Dialect Summary lists for each dialect: * the features supported by VS COBOL * historical details of when such support was introduced to Micro Focus produced compilers * details of the compiler directives which can be used to secure compatibility with the dialects
