External Resources
External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
Changes made to a preference file during a session are reflected in the session by re-reading the preference file using Open or Append in the File menu. Items in the new preference file overwrite items with the same names in the current session.
Some external resources can be registered using a *Register() statement or *Begin() block. Import templates, export templates, external readers, and external functions can be registered using *Register() statements. Statistics templates, math macros, report definitions, and materials can be registered in *Begin() blocks.
