     IDNTYP
 
     IDNTYP sets character or numeric station identifiers to be used for
     input or output.  The valid values are STID and STNM.  STID specifies
     station character identifiers; STNM specifies station numbers.
 
     If the value in IDNTYP is not STNM, the default of STID will be used.
 
     For example, to update station headers in SFSTNS:
 
       IDNTYP =        STID -- compares character ids in file with those
                               in the station table
 
       IDNTYP =        STNM -- compares numeric ids in file with those
                               in the station table
