    6 7 1 1 0                15  

    Assume 3 sets of data, each with sentinal 0. 
    Include a prompt such as "enter a list of numbers with sentinal 0: ".

    f.     
    input:                   output:                             
                               
    2 6 3 1 5 0              17

    6 7 1 1 0                15     
    -99                      
     
    Assume an unknown number of data sets, each with sentinal 0 and 99 at end of all sets. 
    Include a prompt such as "enter a list of numbers with sentinal 0. A sentinal of -99 
    indicates no more lists".
