theorem Th22:
  Data-Locations SCM R = Data-Locations SCM
proof
  Data-Locations SCM misses {NAT} by AMI_2:20,AMI_3:27,ZFMISC_1:50;
  then
A1: Data-Locations SCM misses {NAT};
  thus Data-Locations SCM R = SCM-Memory \ ({IC SCM R}) by Def1
    .= SCM-Memory \ ({NAT}) by Def1
    .= Data-Locations SCM \/ ({NAT}) \ ({NAT})
        by AMI_3:27
    .= Data-Locations SCM \ ({NAT}) by XBOOLE_1:40
    .= Data-Locations SCM by A1,XBOOLE_1:83;
end;
