Applying the B technologies to CICS

Abstract

Abstract. This paper z reports on the experiences of IBM ttursley in using the Z notation and the B-Method [Abr95] [Abr93] in developing new function for IBM's CICS product 4 [IBM94]. A major constraint on the project was the need to produce code that not only corresponded to its required function, but also met a number of stringent non-functional requirements in areas such as integration, performance and maintenance. The Z notation was used to capture the required function, and the resulting specification was hand-translated into AMN. The B-Toolkit, with project-specific extensions, was then used for the development down to PL/X code. The success of this endeavour is discussed here. The use of Z and the B-Method were very successful in addressing the new functional requirements. Meeting the non-functional requirements, however, was more difficult.

Proof and Refutation in Formal Software Development

“…The B method [1] is a "model-oriented" formal method providing notations and support tools for many of the activities in the software development lifecycle. It is currently being used in several industrial organisations [15,3,4,16,9,6].…”

Formalisation and Verification of the GlobalPlatform Card Specification Using the B Method

“…It has been successfully applied in large industrial projects as the Meteor automated subway in Paris [7] and the IBM Customer Information Control System (CICS) [8]. It is also commonly accepted in the smart card field as a suitable method for formalising and verifying applications [9,10] or particular aspects of smart card platforms [11][12][13].…”
