Working with Versions of Functions and Messages

A version is a model object that is a copy of either a function (FUN) or a message (MSG) in the same model. A function or message can have an unlimited number of versions. Three benefits of using versions are:

• You can test changes on a version of a function or message without interfering with the functionality of the existing model object.
• When you finish testing a new version of a function or message and make it active in the model, the original model object remains unchanged and can easily be made active again if needed.
• Only the currently active version of a function or message is displayed on CA 2E editing panels. As a result, the panels are not cluttered with inactive versions.
