In addition to the objects included in the report (pages, bands, "Text" and other objects), some service objects are available in the script, which may be of some use when managing report's construction. The "Engine" object, which we used in the previous chapter, refers to this kind of objects. The list of service objects is given below:

- Report - the "Report" object;
- Engine - the link to the report's slider;
- Outline - the link to the "Report tree" control element in a preview window.

Let us examine each of the objects.
