That should be _my_ds().  It's a function, not a variable, so trying to
use its _address_ as the selector won't work for obvious reasons.  :) 
This is actually an error in the DJGPP docs, because they lead you to
believe that the above is the correct way to use _my_ds().  The DJGPP
v2.01 docs fix this problem, so I recommend you download the newer
version.
