theorem Th26:
 for I being really-closed Program of SCM+FSA
  holds Goto  (card I + 1) ";" I ";" Stop SCM+FSA
     is really-closed
proof let I be really-closed Program of SCM+FSA;
A1: card(I ";" Stop SCM+FSA)= card I + card Stop SCM+FSA by SCMFSA6A:21
     .= card I +1 by COMPOS_1:4;
  Goto(card I + 1) ";" I ";" Stop SCM+FSA
  = Goto(card I + 1) ";" (I ";" Stop SCM+FSA) by SCMFSA6A:25;
 hence thesis by Th25,A1;
end;
