Abstract

This paper explores some critical issues in the future expansion of COBOL, particularly in view of its support for the fundamental principles of object-orientation and components. This paper explores the class definition and design by contract issues of the proposed ISO standard for object-oriented COBOL. It explains how the careful application of object-oriented COBOL can increase the consistency of COBOL software specifications, requiring special attention on the side of COBOL developers. In particular, the exception handling mechanisms in the proposed COBOL standard are examined. In the absence of full implementations of the proposed standard, practical work-around architecture for administrative business applications is briefly discussed. Reading the paper assumes a minor knowledge of the COBOL syntax.
