The remaining data is entered with the following keystroke sequence:
12000 gK
8000 Þ gK
178500 gK
Figure 7
Answer: The keystrokes presented above indicate the correct entries.
Example 2: The cash flow diagram had all of its information used to compose the cash flow data in the HP12C
memory. Show how to check that they were entered correctly.
Solution: Now that all data is entered, checking for its correctness is possible in two ways. The most common way is
the sequential check and the keystroke sequence for this checking is as follows:
:w

This is the number of the last register used to store the cash flow data. It will be needed later.
:gK

This is the amount of CF

. The sequential checking works backwards, and each time :gK is
pressed, n is decreased by one unit. Now check CF

and when checking CF

verify N

as well.
