Reference manual / Z-related commands / Proof rule commands / constraint


The constraint command copies a selected global constraint from the specification into the antecedent part of the inspected goal. If both global constraint and goal are in the specification window, the global constraint must be the crossed selection. The constraint may appear anywhere in the specification. Newline-separated outermost conjuncts in the global constraint become comma-separated antecedents in the sub-goal, preceding any existing antecedents.

Due to difficulty of referencing global constraints, the constraint command cannot be used in tactics.
