Yeah - that bugs me too.  The DOS 2.0 manual DOES have the desired
info, but not always clear or correct info.  A few books on the market
have SOME of the info, but the ones I've seen do NOT have all of it and
DO NOT tabulate it in one place for reference.  An example is `Assembly
Language Primer for the IBM PC & XT' by the Waite Group.  Their
explanations are at least clear, but the book is suitable as a tutorial
and NOT as a reference, at least for me, because of the incompleteness
and the difficulty of finding what *is* there.  I am told that IBM does
publish a DOS technical reference manual for 2.1 containing the info
you (and I) want.  In fact, I plan to buy one soon.
