Don't get fooled by the /dx entries in modules like init. If you look 
carefully, you will see that /DD is $2F $44 $C4. If you use dEd to make 
a change in the ascii section and enter /DD you will get $2F $44 $44. 
These module names have the last byte with $80 added as a termination 
indicator. So /DD is above and /D0 would be $2F $44 $B0.
