Preface

This COBOL system supports many dialects of COBOL. This guide describes how to migrate RM/COBOL and DG Interactive COBOL applications to run with this COBOL system.

This COBOL system supports the COBOL language described in your Language Reference and Language Reference - Additional Topics.

Audience

The aim of this Guide is to enable you to migrate from any of these environments:

• RM/COBOL
  
  
• DG Interactive COBOL

to this COBOL environment. It is intended to be used by users who 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.
  
  
• 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.

Any error messages and numbers that may be returned when you submit your program to this COBOL system or when you execute the resulting code are different in the two environments. This should present no problems, but is something of which you should be aware.

It is assumed that you are familiar with the COBOL language, and have access to the Server Express documentation.
