  10.  
  11. I've added the following define to events.h:
  12.  
  13. #define KEYON(thekeys,whichkey) (((char *)thekeys)[(whichkey) / 8] & \
  14.     (1 << ((whichkey) & 0x07)))
  15.  
  16. (don't forget that Pascal numbers bits backward).
  17.  
  18. This way looks clean at least, (and compiles well).
