Following along the lines of BartdB's suggestion, you can also verify that the cash flows have been entered correctly by using the "cash flow editor". To activate it, press RCL CFj. Then you can step through each cash flow entry (both the value and repeat factor) by pressing the + and - minus keys. There will be a final "blank" value in CF 6 when stepping through the entries this way. To exit the cash flow editor, press the C (clear) key.
