APPENDIX G 



DESCRIPTION OF THE COMPUTER PROGRAM FOR 

 PLOTTING BEACH PROFILES 



This computer program is a simple plotting routine developed to 

 specifically handle beach profile data. The program is written in ALGOL 

 and can handle from 1 to 10 profiles per plot. Using an 11-inch 

 Calcomp pen and ink plotter, the finished plot is 8 inches by 35 inches 

 in dimensions. Scales for the plot are labeled in both metric and English 

 units and have a 10 times vertical exaggeration. 



In use the program is stored in a file on the disk storage of the 

 UCSD Burroughs 6700 computer during the time the plots are to be made. 

 Disk storage saves time by having to compile the program only once. 

 Data cards consisting of one x and y coordinate per profile data point 

 and control cards for each survey are then run to make any number or 

 combination of plots. Included below is a description of the program 

 control cards and a complete listing of the program. 



DESCRIPTION OF PROGRAM CONTROL CARDS 



There must be one set of the cards described below for each profile 

 to be plotted. 



Card #1 (free format, i.e., each number followed by , ) 



(1) N, number of profile data cards 



(2) S, symbol code number to indicate what symbol will 

 be used to mark each set of data 



*(3) F, flag for whether or not to complete plot with 

 this profile (see code below) 



Card #2 (format 2A6) 



(1) key to be printed with symbol in right margin (maximum 

 of 12 characters) Example: 12SEPT72NR 



DATE RANGE 



Card #3 3 ■* 3 + N (format 2F 10.3) 



(1) X, for profile in feet (1st 10 columns)) 



f must have 



(2) Y, for profile in feet (Columns 11-20) ) decimal point 

 Note: These cards must be arranged in ascending order of X.
