Re: TVM WP34s trouble Message #3 Posted by fhub on 28 June 2013, 6:49 a.m., in response to message #1 by JimP
Hi Jim,
the only thing I could imagine is that you didn't press the (prefix) key [A] before [D].
Maybe you thought that [A] as prefix is only needed for entering a value and not for calculating, but the prefix [A] is needed for both, entering and calculating any of the five TVM values.
Assuming you've started the TVM solver with XEQ'TVM' (or selecting it from the CATalog and press XEQ), here's an example of a calculation for PMT:
10 [A][A] enters N and displays N=10
5 [A][B] enters I and displays I=5
1000 [A][C] enters PV and displays PV=1000
-2000 [A][->] enters FV and displays FV=-2000
[A][D] calculates PMT and displays PMT=29.50457...
In fact [A] is always necessary as prefix before any of the 5 TVM keys [A]...[->], and it just displays 'N I PV PMT FV' for about 10 seconds (waiting for your next keypress). Whether you _enter_ or _calculate_ any value depends on if you previously have entered any number: if you've entered a number it is just stored, but if you did not enter a number before, then this value is calculated.
