Changes in GC14-7383-00 (June 2013)

This migration guide has been reorganized for Enterprise COBOL 5.1. If you have not yet completed your runtime migration to Language Environment®, see Chapter 3. Planning the move to Language Environment in the Enterprise COBOL 4.2 Compiler and Runtime Migration Guide for help in completing your runtime migration.

Primarily, the following changes have been made to this Migration Guide:
  • Removal of the information related to Language Environment
  • Addition of specific chapters for migrating from Enterprise COBOL 3 and Enterprise COBOL 4
  • Addition of a section on Enterprise COBOL 5
  • Addition of a section on upgrading your COBOL compiler along with other IBM® products. That includes information about Debug Tool, CICS®, and Db2®. Please see Enterprise COBOL migration and other IBM products for more information.

There is a lot of information in this guide but most of it is not needed by most customers. For example, if you are moving from Enterprise COBOL 4 and you have completed your runtime migration for all applications, you only need to look at a few sections. For details, see Upgrading from Enterprise COBOL Version 4, Compiling Enterprise COBOL Version 4 programs, and Changes with Enterprise COBOL 5 and 6.
