| Research Abstract |
We have developed a method, which is an extension of the stepwise refinement method, for correctness-preserving transformation of programs that make use of advanced features such as pointer manipulations and exceptions. We have shown that each feature has a corresponding logical system, namely, separation logic for pointer manipulations and four-valued logic for exceptions. It has been shown that the correctness of programs is formally guaranteed by developing formal proofs on computers, based on each particular logical system.
