MSG-IDE terminology

File

The physical containers for objects in a message AIM. Files are saved individually with a .fle extension. File names have a maximum of 256 characters.

Child file

A file nested within another file. Saving a parent file does not automatically save the associated child file because the parent file contains a reference to the child file, not the actual file

Parent file

Any file that contains a child file. When files are nested more than two deep, a file can be both a parent and a child file.

Peer file

A file at the same level as another file.

Root file

Any file displayed at the first level in the objects list of the Browse dialog box.

Project

A file with a .prj extension. This file is run as the message AIM. A project can contain only one file or multiple child files

Domain

Logical containers for the objects in a message AIM. MSG-IDE objects require a domain. A file can contain zero or multiple domains, depending on the requirements of your program; however, all objects in a project must be within the scope of a domain, even if an individual file does not contain a domain.
