(12C) Convenient Financial Display Mode

[Gamo]

HP-34C Owner's Handbook demonstrate the program that computes and pauses to display the future value [FV] of a compound interest saving account in increments of one year according to the formula: FV = PV(1+i)^n

Since 12C already have TVM formula build-in this make programing much shorter than the 34C version.
This program is very handy when you like to see your saving grow through the incrementing years.

How to operate: f [FIN] f [REG]
Input [i] and [PV] then [R/S] the program will continue running until you press any key to stop, or until the 12C overflows.
Remark: PV must be negative according to the Cash Flow Sign Convention

Example:
Initial interest rate 6% [i]
Initial deposit of $1000 [PV]

6 > [i]
-1000 > [PV]
[R/S]
Answer: 1st year, $1060; 2nd year, $1123.60; 3rd year $1191.02; etc.

Code:


01  1
02  STO 1
03  RCL 1
04  PSE
05  [n]
06  [FV]
07  PSE   // may add more pause for longer display of FV
08  1
09  STO+1
10  GTO 03

For reference this is the program from 34C Owner's Handbook

Code:


LBL A
FIX 2
STO 0
Rv     // below this line you may add [EEX] [2] [÷] 
1
STO 1
+
STO 2
LBL 0
RCL 2
RCL 1
PSE
Y^X
RCL 0
x
PSE
1
STO+1
GTO 0

To run:
.06 ENTER 1000 CHS f A
If add EEX 2 ÷
6 ENTER 1000 CHS f A
