Changes in GC14-7383-00 (June 2013)

This migration guide has been reorganized for Enterprise COBOL Version 5.1. If you have not yet completed your runtime migration to Language Environment®, please refer to the previous version of this information. You can use the Enterprise COBOL V4.2 Compiler and Runtime Migration Guide at http://publibfp.dhe.ibm.com/epubs/pdf/igy3mg50.pdf 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 Version 3 and Enterprise COBOL Version 4
  • Addition of a section on Enterprise COBOL Version 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 Version 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 Version 5 and Version 6.
