    ErrorCode: Text[1024];  
    ExpectedErrorCode: Text[1024];  
    FileObj1: File;
    FileObj2: File;
    Text0001: Label 'The error code is not valid. Expected: %1. Actual: %2. Error message: %3';
begin
    ExpectedErrorCode := 'StreamIO';  
    FileObj1.CreateTempFile;  
    AssertError FileObj2.Create(FileObj1.Name);  
    ErrorCode := GetLastErrorCode;  
    if ErrorCode <> ExpectedErrorCode then  
      Error(Text001, ExpectedErrorCode, ErrorCode, GetLastErrorText);  
end;
