Parts

The part is an independent part of an application. No part can exist inside of another part. Parts can be as large as a Program, or as small as a single DataItem. You use three main kinds of parts in EGL programming:

Main parts such as FormGroups, Libraries, and Programs have the same name as the source file. You can create source files that have no main parts at all; for example, to store some kinds of data parts.

A variable is a named entity in either an EGL logic part or Record. Variables are based on data parts, which means that a variable reserves storage for a particular kind of data. For more information, see Variables.

If you declare a variable or constant in a part, that identifier is in scope throughout the part:
