<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The subject of this paper is a program verification method that takes into account abortion caused by partial functions in program statements.

This work considers the program constructs of nondeterministic sequential programs and also deals with the synchronization statement of parallel programs introduced by Owicki and Gries [7].
