HP-12C Programming



#6

I'm inputing a program from the user guide, I follow the guide by the letter. My sum still comes out to zero as in the program is not working or it hasn't registered?


#7

the program in question is on page 137 of the user guide, i'm trying to solve for yield and to solve for yield with a 10% residual

Hello, Graham;

I'd like (and I want) to help you, but I think the owner's handbook you have is different of the one I have. Just for checking purposes: the one I have in hand is: "HP12C Owner's Handbook and Problem-Solving Guide" (English), dated May 1984, Revision F. Is it the same as yours? If so, the program you're talking about is the example shown under "Multiple Programs"; is it correct?

I guess my "HP12C OH&PSG" is not the same as yours. In this case, may I ask you what program are you typing in? A brief description would help us (me?) locating it.

I also have the "HP12C Platinum OH&PSG" (English) in hands, and it has a program listed in p. 137 that is meant to be used when you're computing a depreciation by using Declining Balance ([DB]) method when acquisition time occurs any time during the year. Is it the program you're talking about?

Anyway, I found a keystroke sequence in the "HP12C Platinum OH&PSG", now in P. 127, that is related to annual yeld computing. Any possibility that this is the one you're talking about? A misplaced "3" instead of a "2" when typing the page #, perhaps?

Another question (forgive asking questions when you're actualy looking for answers): are you using an HP12C or an HP12C Platinum?

Sorry not answering your question, instead adding four others. No help, I know, I just want to "locate" myself so I'll try to help you anyway.

Best regards. (I almost did not post this...)

Hi Luis
I have the HP-12C standard
My Book is the Owners handbook and problem solving guide dated Nov 94 edition 3.
This is type of scenario I'm trying to get my machine to do:
" Equipment worth $5000 is leased for 36 months at $145 per month. The Lessee has agreed to pay the first and last month's payments in advance. At the end of the lease, the equipment may be purchased for 10% (1500) what is the annual yield to the Lessor if the equipment is purchased?
I send a lot of lease transactions to leasing companies that are structured as 10% PUT (Purchase upon termination) and I want to check that the yields are not excessive to the customer.
Thanks in advance!
Graham

Graham - that example is on page 177 of my old 1986 12C manual. HP give a keystroke solution - no program. Note 10% of 5000 is 500, not 1500??

Hi to Luiz!
