Abstract
The LISP language provides a useful set of features for prototyping knowledge-intensive, clinical applications software that is not found In most other programing environments. Medical computer programs that need large medical knowledge bases, such as programs for diagnosis, therapeutic consultation, education, simulation, and peer review, are hard to design, evolve continually, and often require major revisions. They necessitate an efficient and flexible program development environment.
The LISP language and programming environments bullt around it are well suited for program prototyping. The lingua franca of artifical intelligence researchers, LISP facllitates bullding complex systems because it is simple yet powerful. Because of its simplicity, LISP programs can read, execute, modify and even compose other LISP programs at run time. Hence, it has been easy for system developers to create programming tools that greatly speed the program development process, and that may be easily extended by users. This has resulted in the creation of many useful graphical interfaces, editors, and debuggers, which facllitate the development of knowledge-intensive medical applications.
