Reference manual / Z-related commands / In situ replacement commands / characterization


The characterization command replaces formulae in which @ parts were omitted by formulae in which those @ parts are revealed. The expressions revealed are the characteristic tuples of the schema texts (actually in forms calculated before any proof steps were applied).

{ t }   \trarrow   { t @ chartuple t }
( \mu t )   \trarrow   \mu t @ chartuple t
( let t )   \trarrow   let t @ chartuple t

Tactic example
