Import Templates and External Readers
The program reads a variety of ASCII and binary formats and have a template-based system that allows you to read formats which are not supported internally. This template-based system uses a language called Import.
External readers can be used to translate ASCII formats that are not supported by Import and binary formats that cannot be read by the built-in readers. External readers are registered using the preference statement, *RegisterExternalReader(). Registering external readers eliminates the need to install a new version of the program to expand its capabilities.
