theorem Th29:
  for ins being Instruction of SCM+FSA st InsCode ins = 7 holds ex
  lb,da st ins = da=0_goto lb
proof
  let ins be Instruction of SCM+FSA;
  assume
A1: InsCode ins = 7;
  then reconsider I = ins as Instruction of SCM by Th8;
  consider La being Nat, A such that
A2: I = A=0_goto La by A1,AMI_5:14;
A3:   Int-Locations = SCM+FSA-Data-Loc;
  A in SCM-Data-Loc by AMI_2:def 16;
  then reconsider da = A as Int-Location by A3;
  take La,da;
  thus thesis by A2,Def12;
end;
