What is ChangeMan M+R?

The M+R Option eases the task of consolidating multiple versions of source code, JCL, documentation, and other types of text with record lengths of up to 240 characters. It bridges site-modified software products and their new releases, and assists both system administrators and application programmers in many of their change management responsibilities.

The specialized context viewing of up to eight merged versions and the rich version editing features make M+R much more powerful than the standard three-way merging tools that merely show whether a particular code line is found in one, two, or three versions.

In M+R, you have four source code reconciliation tools (Reconcile, Consolidate, Synchronize, and JCL Compare) that recognize different kinds of changes in multiple library versions and helps you reconcile changes into an error-free updated consolidated version.

M+R generates and maintains an elaborate database of the source code differences. It takes up to eight versions of an original text and displays their combined relationships using a design that makes the consolidation quick, accurate, and easy.

The merged versions are available to you in the form of specific easy-to-manipulate views so that you can quickly understand and reconcile conflicting differences in the versions.
