ABL annotations enable you to include meta data in your source code. Among the many uses for ABL annotations are identifying procedures and user-defined functions for use with the Progress Sonic Enterprise Service Bus (ESB), and indexing your code base with the OpenEdge Meta Catalog. The compiler treats annotations as comments, so they do not affect how your code runs.

The ABL Editor provides a wizard that simplifies the task of adding annotations to selected files. The wizard provides templates for ESB and Meta Catalog annotations. You can also add your own custom annotation templates.
