   I don't use a debugger with these .bin files. I have a routine I jump to   
   that reads a pushed word and prints 4 hex digits in the corner of the   
   screen and then goes into infinite loop.  Crude but pretty useful. I   
   have similar routines that use call and ret but this one is to be used   
   with jmp. Well, what I had done was type   
      
   push ax   
   call vuhex   
      
   instead of   
      
   push ax   
   jmp vuhex   
      
   vuhex isn't made for call and  ret.   
      
   It's interesting that I made the mistake because I was using jmp vuhex   
   for checking the screen buffer coordinate in dx register and getting   
   correct results. Then I tried reading screen memory with 'call' and   
   wondered about reading screen memory.   
      
   Thanks everyone for your help. Sorry for the bother.
