let I be InitHalting keepInt0_1 Program of SCM+FSA ; :: thesis: (IExec I,s) . (intloc 0 ) = 1
not intloc 0 in NAT

proof

A1: intloc 0 in Int-Locations by SCMFSA_2:9;
assume intloc 0 in NAT ; :: thesis: contradiction
hence contradiction by A1, SCMFSA_2:13, XBOOLE_0:3; :: thesis: verum

end;

then A2: not intloc 0 in dom (s | NAT ) by RELAT_1:86;
ProgramPart (s +* (Initialized I)) halts_on s +* (Initialized I) by Th5, FUNCT_4:26;
then A3: ( Initialized I c= s +* (Initialized I) & ex n being Element of NAT st

thus (IExec I,s) . (intloc 0 ) = ((Result (s +* (Initialized I))) +* (s | NAT )) . (intloc 0 ) by SCMFSA6B:def 1
.= (Result (s +* (Initialized I))) . (intloc 0 ) by A2, FUNCT_4:12
