  13. Forgive my ignorance....
  14. what would happen if one did a preprocessing pass through the EXE files when
  15. loading replaced all occurences of POPFD with INT NN (which would trap)?
  16. Of course one would not catch self-modifying code and things that swapped in
  17. code after starting, but still, it seems easier than emulating a 600-point
  18. API....
  19.  
  20. I would guess that POPFD is a short instruction, that's why I think of
  21. INT NN rather than a subroutine call....
