....would be desirable. For example, there are no convenient facilities for focussing on parts of a subgoal, say to do a single rewrite of a subterm. The use of pattern matching and the ML programming language enables this to be overcome to some degree. This is in contrast to a system such as EVES [5] or PVS [9] where all the proof steps One of the major needs for the constructs THEN ALL NEW SUBGOALS and REPEAT ALL NEW SUBGOALS is to be able to focus on one subgoal in isolation, which is not easily supported by Isabelle. The flattened representation of subgoals meant that it is not ....

....: 45 B. 8 Conclusions : 45 EVES Project Technical Report TR 91 5449 02 1 1 Introduction The Z EVES project had three primary goals: ffl to assess the Z notation [51] ffl to determine the feasibility of using EVES [19, 18, 38, 46, 41] as a proof tool for Z, and ffl to adapt the Z Mathematical Toolkit (defined in [51] for use in EVES. The project therefore proceeded on several fronts. In order to familiarize myself with the Z notation, I read the Z reference manual [51] a less formal summary of the language [22] and a ....
