reserve x for set,

theorem
  for ins being Instruction of SCMPDS st InsCode ins = 14 holds ex k1 st
  ins = goto k1
proof
  let I be Instruction of SCMPDS such that
A1: InsCode I = 14;
  I in {[0,{},{}]} or I in S1 or I in S2 or I in S3 or I in S4 or I in S5
        by Lm1;
  then consider k1 being Element of INT such that
A2: I=[14,{},<*k1*>] by A1,Lm3,Lm4,Lm5,Lm6,Lm7;
  take k1;
  thus thesis by A2;
