Roger, I see what you did there, and that makes since to me know. That is what I was trying to achieve, but I was not getting there. Thanks for clearing that up.
Gentlemen, Now I have moved on to trying to do the same thing for masterReset, using the exact same code that Roger has implemented in my spec, but now I am getting an error when I try to push the consistency goal. :) z_get_spec ñmasterReset®; val it = ô (masterStop BOOLEAN ± masterReset BOOLEAN) ± true : THM :) z_push_consistency_goal ñmasterReset®; Exception Fail * Specification of z'masterReset is not of the form: `Consistent (Ì vs[x1,...,xn]·p[x1,...,xn]) ô ...' [z_push_consistency_goal.46007] * raised Is this because the that it has already because it was proven consistent with the masterStop?
