do considered od: A contribution to the programming calculus

  • Eric C. R. Hehner
Article

Summary

The utility of repetitive constructs is challenged. Recursive refinement is claimed to be semantically as simple, and superior for programming ease and clarity. Some programming examples are offered to support this claim. The relation between the semantics of predicate transformers and “least fixed point” semantics is presented.
