RELATIVE POSITIONING

  >4         shifts nest cursor up in 4 positions. 
  <3         shifts 3 positions down

  >          the same as >1
  <          the same as <1

  =x,y,z     establishes states x, y, and z starting from the CURRENT STATE; 
           CURRENT STATE means top stat in global-nest;
           the effect of character "=" is quite different 
           in case of absolute postioning;



ABSOLUTE POSITIONING

  =0         - sets nest cursor on the first state in global queue;
  =9         - sets nest cursor on the 9-th state in the global queue starting from the beginning of queue.
  =3,x,y,z   - equivalent to queue: =3 =x,y,z
             - establishes states x, y, and z starting from the third absolute position;
               x will be third state from the bottom;
  =          - the same as =0
  =0,x,y     - equivalent ot queue: = =x,y
             - sets x and y starting from the bottom;
