   PDOS/86

   I think PDOS/86 should probably only be compatible   
   with MSDOS at the PosWriteFile() etc level, just as   
   PDOS/386 is.   
      
   In particular, for allocating memory, I would like the   
   "allocate memory" call to return a seg:offs rather than   
   just a seg. In a flexible segment shift environment,   
   this would allow multiple requests to share a single   
   64k page, even if the segment shift is 16 bits.   
      
   But this introduces another issue. Callers have   
   traditionally cared about being properly aligned, but   
   segmentation introduces a requirement for the   
   caller to be able to request that the entire block   
   be within a single segment. Huge memory model   
   callers don't care about that, but everyone else   
   does, so some sort of indicator, or different   
   INT 21H function code would seem to be   
   appropriate.
