and the seven subsequent lines of FORTRAN code delete the statements identi- 

 fied by "DEPTH. 23" through "DEPTH. 26" in subroutine DEPTH and replace them 

 with the seven new lines. These modifications alter the format used to read 

 bottom bathymetry data; and, since the water depths on the file happen to be 

 negative numbers, a sign change is programmed into the procedure. The 

 "Update" correction 



*D MAIN. 203 



DMULT=10.0 



replaces the line in the main program identified by "MAIN. 203" with the sub- 

 sequent new line of code. This correction changes the accuracy of the depth 

 matrix in the printed output from whole metres (or other units) to tenths of 

 metres (or other units). As it is written, the model prints out water depths 

 to the nearest whole foot (metre or centimetre), wave heights to the nearest 

 tenth foot (metre or centimetre), and wave angles to the nearest degree. 

 Changes in output accuracy must be made via "Update" corrections. Users are 

 referred to the statements "MAIN. 194" through "MAIN. 206" in Appendix F for 

 further explanation. 



88. These "Update" corrections have illustrated the use of the DELETE 

 (*D) command which deletes line(s) of text. Other frequently used "Update" 

 commands are the INSERT (*I) commmand, which inserts text after a certain 

 line, and the BEFORE (*B) command which inserts text before a line. Users 

 interested in making source code changes should first consult the "Update" 

 manual referenced earlier. 



Output Files 



89. Two permanent output files are generated during the course of model 

 execution on the CYBER 205. These same two files plus one additional file are 

 generated during the course of execution on the front end (CYBER 865). Output 

 file names given in Figure 7 will be used in this discussion. Information 

 contained on the printed output file RCPPRNT is independent of the choice of
