However, problems involving more than 80 cash flows can be handled
if among the cash flows there are equal consecutive cash flows. For such problems,
you merely enter along with the amounts of the cash flows the number of times —
up to 99 — each amount occurs consecutively. This number is designated N

This method can, of course, be used for problems involving fewer than 80 cash
flows — and it will require fewer storage registers than the method described
above under Calculating NPV for Ungrouped Cash Flows. Equal consecutive cash
flows can be entered using that method — provided there are enough storage
registers available to accommodate the total number of individual cash flows. The
facility of grouping equal consecutive cash flows is provided to minimize the
number of storage registers required.
When entering cash flow amounts — including the initial investment
— remember to observe the cash flow sign convention by pressing Þ
after keying in the amount for a negative cash flow.
If you have stored a program in the calculator, the number of registers available for storing
cash flow amounts may be less than 81.
