Comprehensive crisis managementd conceptual problems. Unfortunately, large bodies of old code exist which were written for untyped or dynamically typed systems, which leave such problems to be detected during execution, often much later and only in response to peculiar or unusual input. A typical example of this syndrome is the c

Lothar Geitler,Elisabeth Tschermak-Woess program of the kind “if object has a certain property then ... else ...”. The approach is based on the key idea that first the calculations performed on an object is duplicated on the object‘s initial property. The so computed property can then be tested against the primary queried property. To dem

An experiment has been performed to see if using the ideas of the special purpose algebra system CAMAL(F) it is possible to make the general purpose system REDUCE perform calculations in celestial mechanics as efficiently as CAMAL did twenty years ago. To this end a prototype Fourier module

Lothar Geitler,Elisabeth Tschermak-Woessis therefore worthwhile to follow this approach in realizing a programming environment which integrates the capability of defining mathematical objects, which can be directly implemented, with that of automatically verifying their properties. From the user point of view, such a system presents sever
