2.5. The Welcome Screen: 



The welcome screen displays overall operational capabilities of the 

 NRIS system in very broad terms. The main purpose of this screen is to 

 notify you that the data management system is active and provide 

 general information to the new user. The screen will not appear again 

 until the system is restarted. 



Fig. 2-1: The Welcome Screen 



After reading the welcoming screen, press any key to continue. All 

 menu selections respond as soon as you press a key corresponding to the 

 menu selection you desire. However, there are certain submenus that 

 do require the use of the Enter or Return key during completion of the 

 menu. These situations will be noted in the appropriate sections of the 

 manual . 



2.6. The Master Menu: 



The MASTER menu will display on the console after you press the <cr> 

 key. This menu is the "heart" of the Rivers Study management system. All 

 of the functions available within the system are called in part from 

 this menu. 



Note that the upper left corner of the menu tells you that you 

 are in the MASTER menu. This display of the menu name is typical 

 throughout the data management system. Another standard function built 

 into the system is the "0" (zero) option. By pressing the "0" key at any 

 menu, you will either return to the MASTER menu or the menu immediately 

 preceding the current menu. Therefore, repeated selection of the 

 "0" option will return you to the MASTER menu and ultimately return you 

 to the operating system.
