assume A1: for s being State of A holds (Exec I,s) . (IC A) = succ (IC s) ; :: according to AMISTD_1:def 16 :: thesis: IC A in Output I
consider s being State of A;
(Exec I,s) . (IC A) = succ (IC s) by A1;
then (Exec I,s) . (IC A) <> IC s by ORDINAL1:14;
hence IC A in Output I by Def3; :: thesis: verum
