Meketon > ihnp4!hou2f!vifl 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. -- Gene E. Bloch (...!nsc!voder!gino)
