执行后的一部分:
#From row number: 369
rule "_369"
  salience 65167
  activation-group "x"
 when
      vhl:AppVhlVO(CUsageCde == "374015", CVhlTyp == "365012", 
      eval(helper.getVhlYear(vhl.getCFstRegYm())>=4 && helper.getVhlYear(vhl.getCFstRegYm())<1000))
 then
      r.putCoef("rate",0.67);
      r.putField("Table.col","Cvrg.NRate");
end
