  16.  
  17. >Certainly it's possible to do that though I've tried to stay away from huge
  18. >pointers because; 1) of the overhead in their use,
  19.     Yes, but it's really not that bad is it?
  20.  
  21.  2) they chew up selectors, 
  22.     Tom, could you please explain this - I don't understand.
  23.  
  24. >and 3) the "conventional" normalized huge pointers can't be used in
  25. >protected mode Windows programming.
  26.     I don't understand this either.  Are there 2 kinds of huge
  27.     pointers? - "conventional" & "non-conventional"?  And why
  28.     can't they be used in protected mode?
  29.  
  30. [...more stuff deleted...]

  32. I reposted this because I thought the questions and Tom's answers
  33. might be of general interest.
