在"Global Script"下的Project functions编写函数cyclicarchive  
 BOOL cyclicarchive()  
 {  
  #pragma code ("kernel32.dll");  
 void GetLocalTime (SYSTEMTIME* lpst);  
  #pragma code();  
  SYSTEMTIME time;  
  Int t1;  
  GetLocalTime(&time);  
 t1=time.wMinute;  
 if(t1==00)  
 {  
  SetTagBit("startarchive",1);  
  return(BOOL)(GetTagBit("startarchive"));  
   }  
 }  
 在Tagloging中的"Properties of process tag"中的"Archive Tag"tab下的Archiving type选择Cycle-selective,在"Event"标签下的"Start Event"内选择cyclicarchive函数
