Before Adding

When you create and define your file, CA 2E automatically creates the following three default access paths for the file: physical, update, and retrieval. These default access paths have default values equal to those of the model values. Generally, the access path options are set when you create your model. However, you can change the values for the access paths at other times.

For more information:

On how to change the model values or values for a specific access path, see the instructions in this guide's "Setting Default Options for Your Access Paths" and "Modifying Access Paths" chapters.
On model values, see the YCHGMDLVAL command in CA 2E Command Reference Guide.

Adding access paths to your design model allows CA 2E to provide you with specific views of the data in the physical files for your application. These views allow you to retrieve data in a format that most suits your needs with less system overhead.

For more information on tailoring your access paths, see the "Tailoring for Performance" chapter in this guide.
