   short InfiniteLoadingLoop (short tableNum)
   {
      char   isLocked = 1;
   // First check if there is no error (bad table number)
      isLocked = PA_Locked(tableNum);
      if(PA_GetLastError())
         return PA_GetLastError();
   // Then, here is an infinite loop. As an example.  Do not do that in your plug-in !
      // while the record is locked.
      do
      {
      // generic C function to delay a process
         MyDelayCurrentProcess(10); // 10 ticks
      // Load the record
         PA_LoadRecord(tableNum);
      } while(PA_Locked(tableNum));
      
      return eER_NoErr;
   }
