let S be non empty stored-program IC-Ins-separated definite realistic steady-programmed weakly_standard AMI-Struct of N; :: thesis: for i being Instruction of S st i is sequential holds
not i is halting

let i be Instruction of S; :: thesis: ( i is sequential implies not i is halting )
assume A1: i is sequential ; :: thesis: not i is halting
consider s being State of S;
NIC i,(IC s) = {(NextLoc (IC s),S)} by A1, Th41;
then NIC i,(IC s) <> {(IC s)} by Th35, ZFMISC_1:6;
hence not i is halting by AMISTD_1:15; :: thesis: verum
