o  You can use this clause only if you have specified a  field  name
      in    the   field   declaration.    You   can   not   specify   a
      facility-specific name for unnamed fields.

   o  Once you have assigned a facility-specific name to a  field,  the
      facility no longer recognizes the field's original name.

   o  Be careful when you use the NAME clause because it enables you to
      assign completely different names to the same field.

   o  Avoid assigning dissimilar names to the  same  field.   The  NAME
      clause  is  designed  only  to allow you to make field names seem
      native to applications languages.
