<br />G01166 <br /> <br />The user can customize some of the interface components. This is done by changing the <br />variable values in the file serupfile, located at the 24nwnthlinterface directory. Each vari- <br />able listed in the file is a global variable, located in the commonf common block. The set- <br />upfile is read in using the routine SETUP, at the start of using the 24MSI. The components <br />of the interface that can be affected are: <br /> <br />1. the strings for the reservoir names <br />2. the strings for the diverters names <br />3. the strings for the input and output parameters <br />4. the color of the screen background <br />5. the color of the table row and column header <br />6. the color of the table cells <br />7. the highlight color <br />8. the message box color <br />9. the line colors for line graphs <br />10.the button up and button down color <br />11. the shadow color for the menus <br />l2.the barplot and the outline color of the barplots <br />13.the background color of the schematic map <br />14.the color behind the physical characterisitic dialogue box <br />lS.the physical limits and range for the RESER V, FORCMAX, FRCREL, TRGCON, <br />UMAINT, REQ'D DIY, DIVSCH, INFLOW parameters, by reservoir <br />l6.the choice of the system call <br /> <br />1.6 Control issues <br /> <br />The control structure which allows the user to navigate through the interface is for the <br />most part hierarchical. That is, menus tend to flow from one to another in a linear fashion. <br />As was mentioned in Volume I, the user can get to the top level of one of the four main <br />modules by clicking on the Control Bar at the top of the main screen. Then the user can <br />follow the menus sequentially through a decision tree by selecting the desired item. To re- <br />turn to the top level of any given module, again the user clicks at the desired module. <br />However, the ESCAPE button allows the user to go back one step in the decision tree. <br /> <br />. The programs that allow this functionality are based on the concept of topological index <br />numbers. These are a unique and hierarchical numbering of every routine in the system. <br />The very topmost level is numbered 100000o. The four modules are numbered, respec- <br />tively, 1100000, 1200000, 1300000, 1400000. Since this first routine in the File module <br />(1100000) has 3 sub-routines that it calls, its child routines are numbered 1110000 (df- <br /> <br />24 Month Study Proiect Dowrnentation Volume II <br /> <br />618191 <br /> <br />6 <br />
