   Go take a look at the PSP, and tell me what is present in the area   
   0080...00FF  Would it matter if it got fully overwritten ?   
      
   Than take a look at 0053...007F   Are you still using FCBs ?   
      
   In other words, you can trash the area from 0053 upto 00FF as much as you   
   like without crashing the program.  Thats a 56 element stack area.   Most   
   always enough for my COM program needs.

   For COM style programs, yes.  For EXE style ?   Well. I allready told you   
   that that isn't always the case (and when). I have no idea why you are   
   ignoring that. :-(

   Thats the wrong direction.  I need SS to stay ontop of CS, not to move away   
   from it.
