CALCULATES AND PLOTS WAVE-RAY PATTERNS FOR A COASTAL AREA OF INTEREST. 

 GIVEN A GRID OF DEPTH VALUES. THE INITIAL POSITION OF A WAVE RAY. AND 

 THE DIRECTION OF TRAVEL AND PERIOD OF THE WAVE. SUCCESSIVE POINTS ON 

 THE RAY PATH ARE CALCULATED FOR OUTPUT ON TAPE. THE PLOTTER USES THIS 

 TAPE TO PLOT THE WAVE RAYS. FOR EACH POINT ON THE PATH, WATER DEPTH 

 AND BOTTOM SLOPE ARE INTERPOLATED FROM THE DEPTH GRID, WAVE SPEED AND 

 CURVATURE ARE COMPUTED ACCORDING TO CLASSIC THEORY, AND THE COORDIN- 

 ATES OF THE NEXT POINT ARE APPROXIMATED BY AN ITERATION PROCEDURE. AP- 

 PROXIMATELY 11,000 POSITIONS OF STORAGE ARE REQUIRED FOR THE DATA (EX- 

 CLUSIVE OF DEPTH GRID) AND THE PROGRAM. IN ADDITION, ONE MEmOry POSI- 

 TION IS NECESSARY FOR EACH COORDINATE INTERSECTION ON THE DEPTH GRID.
