COMPUTES HOURLY VALUES ALSO TIME AND HEIGHTS OF HIGH AND LOW WATER 

 USING THE HARMONIC METHOD IN WHICH THE CONSTITUENT TIDES ARE COMBINED 

 INTO THE RESULTANT TIDE. HOURLY VALUES ARE SCREENED TO DETERMINE BE- 

 TWEEN WHICH HOURS A TIDE EXTREME WILL OCCUR. THEN CALCULATION AND COM- 

 PARISON OF THE TIDES ARE MADE AT 0.1 HOUR INTERVALS UNTIL THE EXTREME 

 TIDE IS DETERMINED. ANY ARBITRARY DATUM PLANE MAY BE SELECTED. THE 

 OUTPUT IS OPTIONAL AND MAY BE HOURLY TIDES. HIGH AND LOW TIDES, OR 

 BOTH. RUNNING TIME FOR BOTH — ABOUT 25 SECONDS FOR ONE STATION FOR 

 ONE YEAR. AUTHORS — N.A. PORE (WEATHER BUREAU) AND R.A. CUMMlNGS 

 (COAST AND GEODETIC SURVEY). EARLIER VERSIONS WRITTEN FOR THE IBM 70^ 

 AND IN SOS FOR THE IBM 7090/9^. REVISED IN 1966. PROGRAM DESCRIPTION 

 AND LISTING ARE GIVEN IN WEATHER BUREAU TECHNICAL MEMORANDUM WTBM TDl-
