Problem conclusion

• The problem was solved  with help  of floating point arithmetic
  for  the  calculation  of  the  buffer pool total hit ratio and
  the values of the buffer pool total counters. All  the counters
  are divided by 1000 and shown with multiplier "K" at the end.
  
  The  reason  of  the  issue  was  incorrect accumulation of the
  32-bits counters QBSTGET, QBSTRIO, QBSTSPP, QBSTLPP, QBSTDPP of
  the QBST section within  31-bits  variables being too small for
  this purpose.
  
  Comments.
  1. Currently ISPF monitoring dialogs can display correctly only
  values  not  exceeding  4295M   (2*32-1) in  the  DGOMSWBM  and
  DGOMSWBR panels. If  a  value  is more  than  this limit, it is
  displayed as a remainder as if  the value  has been  divided by
  the 4295M constant.
  2. Hit ratio -0.0 means  that  the  value is small and negative
  but not equal 0.
