assume that
A1: InsCode I = InsCode (halt (SCM R)) and
o in Data-Locations (SCM R) ; :: thesis: (Exec (I,s)) . o = s . o
I = halt (SCM R) by A1, Th8, Th16;
hence (Exec (I,s)) . o = s . o by EXTPRO_1:def 3; :: thesis: verum

end;

hence for b₁ being InsType of (SCM R) st b₁ = InsCode (halt (SCM R)) holds
b₁ is jump-only by AMISTD_1:def 3; :: thesis: verum
