RSX-11M versus RSX-11D: compatibility and conflict. [Incompatibilities in conversion of one software system to another]
As RSX-11M and RSX-11D continue to diverge, more and more users are finding it necessary to run both systems for similar ranges of applications. This situation can impose an unacceptable cost in software development and maintenance. Compatibility in utilities, system files, system features, and code at source and object level offers a realistic first step to reduce this burden. This report presents a discussion of the incompatibilities uncovered in converting a large volume of software from one operating system to the other, as well as the techniques developed to circumvent these problems. Code conversion and long-term software maintenance are discussed with respect to specific system incompatibilities. Finally, management and software engineering tools are discussed as they apply to the conversion and maintenance effort.
