(41) Profit on Pricing Solver

[Gamo]

Thank You Dave

Thanks for the review.

The algorithm use is by attemping to find the Markup.
The key to all the answer is first to get the answer for Markup.
If the unknown is Markup then the special formula is use to
convert Margin to Markup and if the Markup is known this same
special fourmula will get the Margin as well.
The flags is very important in this type of problem since user can
enter data in many combination pair of data and still get the answer.
The flowchart is available in the HP-12C link provided below.

I intended to use alpha labels because
when press and hold the key for less than a second
display will show that label name effect.

The flags used in program seem to work anytime
even though the new problem is enter without clearing flags.
The RESET option is only use for clearing the data registers.

The reason that I write this program because HP-12C doesn’t include
this function where most Financial Calculator have it.
I also write this program for 12C too, but to enter data user must
fill the four data in stacks and run. The answer will be in the TVM labels.
To see the answer simply recall TVM label.

My first HP calculator is the HP 10BII and it got this Pricing Calculation feature.
This program work better than the 10BII because it can calculate between
Markup and Margin by itself.

I’m very thankful to Dieter who help make this program possible.
