By manipulating programs to reorganize the way they compute their results, it is possible to improve program performance in certain desirable directions. Further, using certain laws of exchange, it is possible to transform concise, abstract, high-level programs into efficient, concrete , underlying representations. This paper explores the notion of using source-to-source transformations interactively as a basis for an approach to program improvement and refinement. Examples of program manipulation are presented that convey both the flavor of the approach and its requirements.

This paper sets some context, raises issues, and provides our initial thinking on the characteristics of effective rapid prototyping techniques. After discussing the role rapid prototyping techniques can play in the software lifecycle, the paper looks at possible technical approaches including: heavily parameterized models, reusable software, rapid prototyping languages, prefabrication techniques for system generation, and reconfigurable test harnesses. The paper concludes that a multi-faceted approach to rapid prototyping techniques is needed if we are to address a broad range of applications successfully no single technical approach suffices for all potentially desirable applications. "ends" sought are perfectly well specified, but the "means" are unknown.
