Editing Cash Flows
In the cash flow list, you can view and modify the current values of a specific cash
flow, or cash flows. Press > or < repeatedly to scroll through the list. To
modify an entry, type a new number and press I with a cash flow displayed.
For example, to change the current value of CF(7) in the example in Table 5-2
from 0 to 200 , with CF(7)= displayed, press 200 and press I.
You can also modify the frequency of a cash flow in the same manner with the

erases the displayed cash flow. Pressing :o inserts a cash flow into the
list before the displayed cash flow.
