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
