Many Predict functions process Predict documentation data as well as implemented code. This simplifies creation and maintenance of documentation and external objects and guarantees consistency between documentation and implementation. This documentation describes in detail the functions which process both documentation and external objects.

This documentation covers the following topics:

Handling of External and Documentation Objects	An overview of the functions which process documentation and external objects. The information provided in this section is essential for understanding many functions described in later sections of this documentation.
Generation of External Objects	A wide variety of external objects can be generated from documentation objects stored in Predict.
Working with File Implementation Plans	Implementation plans are used to simplify the generation of external objects.
Incorporation	Predict objects can be created by incorporating information from implemented objects which are stored in an external environment.
Comparison	Predict objects and external objects can be compared, and if any inconsistencies are detected, either the documentation or external object can be updated.
Administration of External Objects	Implemented objects that are connected to Predict objects can be administered using Predict functions.
Preprocessor	The Preprocessor inserts copy code generated from Predict file objects into third generation language programs and writes XRef data which documents the use of these definitions and the calls of external members.
