/ENUMERATION_SIZE=keyword D=platform-specific

 Controls the allocation of unpacked enumerated  data  types  and
 Boolean  data  types,  which  are considered to be an enumerated
 type  containing  two  elements.   Note  that   specifying   the
 ENUMERATION_SIZE  attribute  overrides  any value you previously
 specified with this qulaifier.

 You can specify the following values for keyword:


    BYTE       
      Allocates unpacked enumerated data types with fewer than 255
      elements in a 8-bit byte. Otherwise, the enumerated type is
      allocated in a 16-bit word.  Default on OpenVMS VAX systems.

            
    LONG       
      Allocates all unpacked enumerated types in a 32-bit longword.        
      Default on OpenVMS Alpha and OpenVMS I64 systems.
