It is argued that systems should be designed for reusability by anticipating change. This goal can be achieved by designing the software by layers of problem-oriented languages, which are implemented by suitably extending a base language. A language layer rarely needs to be adapted to changes, only the application (i.e. algorithm) has to be changed. The authors illustrate this methodology with respect to VLSI CAD programs and a particular language layer: a language for handling networks. Such a language consists of a base language (EC or Lisp) plus data types, operations and control structures that are relevant to network problems. The network language is but one of several languages used; other languages used deal with sets, two-dimensional layout structures, waveforms, etc. The discussion of the network language illustrates this technique.<>
