   integer address greater than 1: that component is preceded by other
   information. DLA descriptors lie between consecutively numbered integer
   components, so those components are not contiguous.
<P>
 
   Any of the segment components may be empty, but the DAS integer address
   space is never empty.
<P>
 
   In a segregated DLA file, all segment components of a given type are
   stored sequentially in the DAS address space of that type.
