Intended for users of the 3RIP text retrieval database, for retrieval system users with a knowledge of the EURONET Common Command Language (CCL), and for 3RIP system managers, this booklet provides a complete description of the 3RIP retrieval system command language. New functions and recent changes in the 3RIP system are summarized, system passwords and command modes are reviewed, the system's standard command vocabularies are described, and the various searching operations of the system are outlined. Record output, system default and format options and designations, the deletion and editing of records, and the development and use of private command vocabularies are also discussed. A section containing advice to managers of 3RIP retrieval systems is also included. System commands are listed in five tables and an index is attached. (JL)
