<p>A technique and an environment-supporting specialization of generalized software components are described. The technique is based on symbolic execution. It allows one to transform a generalized software component into a more specific and more efficient component. Specialization is proposed as a technique that improves software reuse. The idea is that a library of generalized components exists and the environment supports a designer in customizing a generalized component when the need arises for reusing it under more restricted conditions. It is also justified as a reengineering technique that helps optimize a program during maintenance. Specialization is supported by an interactive environment that provides several transformation tools: a symbolic executor/simplifier, an optimizer, and a loop refolder. The conceptual basis for these transformation techniques is described, examples of their application are given, and how they cooperate in a prototype environment for the Ada programming language is outlined.</p>
