|> 20E8:011F CD20          INT  20          Dos Exit Interuppt

Two things:
  1)  Using INT20 to exit a program isn't recommended.  Try using the exit
procedure under INT 21.
  2)  Is the address of INT 20 correct (011F).  If so, then it overlaps the
end of the INT 21 instruction right above it.  (011E+02=0120)  SHould be:
   20E8:0120 CD20          INT  20          Dos Exit Unteruppt [sic]
