o  Only  VAX  DATATRIEVE  supports  the  QUERY_NAME  clause.   Other
      processors ignore it.

   o  You can specify a query  name  for  a  field  only  if  you  have
      specified a field name for it in the field description statement.
      You can not specify a query name for unnamed fields.

   o  QUERY_NAME  is  different  from  NAME  because   VAX   DATATRIEVE
      recognizes both the query name and the original field name.  With
      NAME, the facility-specific name is the only name  recognized  by
      the specified language or language processor.

   o  Choose a query name that is shorter and easier to  remember  than
      the  actual field name.  You can then choose a field name that is
      descriptive of the field's contents and purpose.

   o  You can use 8-bit characters in CDDL quoted strings.
