tAnReDos--a circle application in evolution

It is not easy to build a computerised medical record system for a microcomputer system. Several aspects of the medical environment require more than just 'off the shelf software. This paper describes some of the properties and possibilities of Circle applications. Circle software has been developed as a result of 15 years of close contacts with medical departments and is meant to be adaptable to any medical environment. Although medical applications usually are very complex, using Circle has been proven to be easy in its use. Above all, Circle applications can always be modified in such a way that they keep pace with the inherent evolution of medical applications.
