Figure 11. Select Counties 



Move to 'Missoula' using the arrow keys or by typing the letter M until the 

 highlight bar is on that selection. Mark the county by pressing Enter, an arrow 

 symbol will mark that county. You can remove the arrow and cancel the 

 selection of the county by highlighting 'Missoula' again and pressing Enter a 

 second time. Use the Exit key twice to return to the opening screen. 



SELECTING THE REPORT FORMAT. Let's use the same report format 

 as we did for the first retrieval. As a result, you will not have to make a 

 selection for this menu item. 



SELECTING THE RIGHT DATA INDEX. Sometimes when you make 

 changes in your retrieval, you will need to decide if you should activate a 

 different data index to make the retrieval run faster. For the present example the 

 options are: 



1. Leave the River Name index activated. This means that the 

 program will search an alphabetized list of stream names. It will move 

 quickly to the first 'Rattlesnake Creek' and 'read' through all of the 

 records with that name (4 records) to find the Rattlesnake Creek located 

 in Missoula County. 



2. Activate the county index instead of the River name index. 



Doing this causes the program to search a list of records organized by 

 county name, that is, all of the records in Broadwater County are grouped
