   Re: POS Sub Addressing

   MCAH is on Internet Archive, unfortunately not freely downloadable. I   
   sign in, "borrow" it, then do screen caps of each page. MAJ Tom OCRs it,   
   then I HTMLize it.   
      
   Note: The MCAH has a goodly part ad rush, pre-90 facts, and stuff from   
   published MCA references. For instance, the subaddressing stuff can be   
   found in the HITR. Also, there are inaccuracies. WBST pointed out that   
   at least one section that I quoted was wrong.   
      
   The "strength" of the MCAH is the scattered nuggets of well written, or   
   re-written, MCA functions. I had considered more HTMLizing, but there   
   isn't enough stuff in it that wouldn't require extensive commenting to   
   bring out the significance of the text.
