The role of auxiliary variables in the formal development of concurrent programs

Lookup NU author(s): Professor Cliff Jones



So called "auxiliary variables'' are often used in reasoning about concurrent programs. They can be useful --- but they can also be undesirable in that they can undermine the hard won property of ``compositionality''. This paper explores the issue of auxiliary variables and tries to set concerns about overuse in a wider context; it concludes with an attempt to recommend constraints on their use.
