Establishes  a  default  table  for the system. Before you specify a
   table  as  the system default, you must load the table into nonpaged
   dynamic  memory  pool  using the LOAD command. The SET DEFAULT_TABLE
   command  reads  the  table  type  (fallback  or  compose)  from  the
   specified  table's header and makes the target table the default for
   its type.

   Before you enable any defaults, the following defaults apply:

        ASCII   - Fallback
        LATIN_1 - Compose validation

      Format:  SET DEFAULT_TABLE table-name
