(12C) Payback Period in Cash Flows

[rprosperi]

Carsten - thanks for sharing, and for all the effort to make such a nice and clear program listing.

I've entered it on an old 12C (not sure what you mean by 'original' since various h/w versions vary in speed up to 1000 times), in this case a USA-made machine from 1988. But I am not getting the expected results, even though I've verified the program listing.

So, perhaps my confusion stems from the user instructions.

1. Do you really enter the initial investment before the cashflows? I believe it will get pushed off the top of the stack.

2. Suggest you provide exact key sequences in your example as many folks (maybe including me) are not familiar with the proper way to enter cash flows.

I assume something like:

14000 [g][CF0]
11000 [g][CFj]
10000 [g][CFj]
10000 [g][CFj]
10000 [g][CFj]
9100 [g][CFj]
etc.

but as I said, I don't have a lot of experience entering cash flows, so maybe this is wrong.

If you can clarify the instructions, I'm happy to time this for you.

Note I have verified I've entered the program correctly (per your listing), but I'm waiting for Dieter to suggest how to take 5-6 steps out of it; he always seems to find a way, and I nearly always learn a little when he does.
