We describe a methodology and supporting programming environment that provide for reuse of abstract programs. Abstract programs are written using notations and constructs natural to the problem domain in a language realized by syntactic extension of a base language. Program transformations are employed to refine an abstract program into its concrete counterpart. We discuss the use of the methodology in the setting of rapid prototyping and custom tailoring
THE reuse of programming has a number of obvious pay-offs—reduction of costs, ...
