Wow, who'd have thunk that this internet thingy would be so informative. > > Study , Study , Study > I did , and now im the worlds greatest Systems programmer .. > Nothing wrong with a little selfconfidence, I suppose. Chortle. Sorry, couldn't help feeding the trolls with this one. I find werty always delightfully entertaining to read.

By the way, as to SPFV etc: 'SPFV(I%,N)=EXPM(LNP1(I%/100.)*N)+1.' DEFINE 'SPPV(I%,N)=EXPM(LNP1(I%/100.)*N)+1.' DEFINE 'USFV(I%,N)=EXPM(LNP1(I%/100.)*N)/I%*100.' DEFINE 'USPV(I%,N)=EXPM(LNP1(I%/100.)*N)/I%*100.' DEFINE This creates variables named SPFV etc. which calculate each result from args on stack, or may also be used algebraically, e.g. 'SPFV(2,50)' EVAL ==> 2.69158802908 'USPV(2,50)' EVAL ==> 31.4236058936 Although there is a builtin TVM solver (TVM command), you can also write the TVM equation as below, and then solve it via STEQ 30 MENU: 'PV/USPV(I%YR/PYR,N)+PMT*(1+B*I%YR/PYR/100.)+FV/USFV(I%YR/PYR,N)' Where PYR is the number of payments per year, and B is 0 for payments at END, or 1 for BEGin mode; actually you should multiply this entire equation by N if you expect to need to solve it for N.

From: Manatee on 21 Dec 2006 20:48 I know about all the other tools out there. I have an iPaq 4700 and a Palm Treo 700p, both with great finance packages. But... I'm a calculator nut. I was the first in my class to own a "pocket" calculator  a Datamath TI2500, in '73. Then I got an HP 25C. Wish I still had it. I do still have the HP 12C I got when I started business school in '82. I love that thing! I've changed the batteries in it TWICE in 24 years. My current collection includes a 42S, a 48GX, a 17B II+, and now the 50g. I don't calculate to live... I live to calculate. :) Peter "werty" <werty(a)swissinfo.org> wrote in message news:1166727644.919695.198850(a)80g2000cwy.googlegroups.com... > > > > Much easier to choose better hardware , give up pulling your own teeth > .... > > Theres new h/w , much easier to program ..

Re sums and cash flows, the 17B could create named lists (or arrays) within its SUM and CFLO applications, which you could also access from formulas in its SOLVE application via a set of special functions: ITEM(listname:item#) [sums] FLOW(listname:flow#) [cash flows] #T(listname:flow#) [repetition counts for flows] SIZES(listname) [sum list length] SIZEC(listname) [cash flow list length] In the 48/49/50, lists or arrays may be stored under any name (or on the stack), the SIZE command returns the number of elements for any list or array, and individual elements are addressable, e.g.: { 11 22 33 44 } 'MYDATA' STO 'MYDATA(2)+MYDATA(3)' EVAL ==> 55 MYDATA \GSLIST ==> 110 ["sum of a list" command] 444 'MYDATA(4)' STO [store into list element] 'MYDATA' 55 STO+ [append new element to end of list] 0 'MYDATA' STO+ [insert new element at head of list] '\GS(n=1,4,MYDATA(n)^2)' EVAL [sum of squares] Where \GS means the "Greek Sigma" character, etc. The builtin statistics functions are also available for the entry and correlation of individual or paired lists, leastsquares fit and predictors, etc. "It's all in there."
