Yes. For normal device assignment, you use the command decoder to assign 
unit numbers to files, which loads the handlers for same.

Adventure uses the USR routines written by Robert Phelps, which allows it 
to dynamically load a driver into memory and open a file at run time. 
Space for those handlers is allocated just above the FRTS allocation.
