# Part 2 - Deeper Details

This portion of the Guide provides deeper information regarding the operation and features of the software.

Chapter 7 describes each of the Builtin functions that the software makes available to you. For each Builtin, you'll learn what it does, how it works, and when to use it.

Chapter 8 will take you through the details of how to move data into and out of your models. This includes Copy, Paste, DDE (for Windows), and Publish & Subscribe (for Macintosh).

In Chapter 9 you'll learn about Sub-models. Chapter 9 provides a set of how-to directions for creating and working with Sub-models on the Map/Model level. It also describes the rules the software uses for the manipulation of diagram objects, whenever Sub-models or Decision Process Diamonds exist within a model.

Chapter 10 details the cycle-time capabilities of the software. There you will learn how to set up a model to collect cycle-time metrics. You'll also learn a number of ways to use cycle-time metrics to determine system performance.

Finally, Chapter 11 provides the necessary details for using arrays to manage complexity in your models. You will find the details needed for setting up one and two dimensional arrays and the internal rules that are enforced by the software.

The chapters in this part of the Technical Documentation are designed to be used as reference material. You may want to skim the Chapters now. Then, when you need an in-depth technical treatment of one of the topics covered, take some time to work through the appropriate section.
