   Mike Westerfield's "Toolbox Programming in C" contains a routine:   
      
   void HandleControl (void)   
   {   
   if ((myEvent.wmTaskData4 & 0xFFFF8000) == 0)   
      switch (myEvent.wmTaskData4) {   
      
   ...   
      
   I can find no explanation for doing this. I believe it's just testing if any   
   of the bits 17 - 31 have been set to one?   
      
   I'd be grateful if someone would explain why this is being done. I imagine   
   I've missed something there or the IIgs Reference Manuals.
