RPN83P: RPN calculator for TI-83+ TI-84+ inspired by HP-42S

[Liamtoh Resu]

Thanks agsain for the great application.

The backgournd information on the state of rpn calculators and dates was a great inspiration
for loading the app on my TI84plus (which I obtained at a thrift store).

I went to the date information page: https://github.com/bxparks/rpn83p/blob/d...DE_DATE.md

I could not figure out how to get to the date menu. I later got it by pressing the [math] key
and pressing the [down arrow] key twice.

From there I was able to figure out the DDAYS function on your application.

I am guilty of not reading all of the documentation.

From the entry:
"DATE Menus

The following menus items are located under the DATE menu. A short synopsis of each menu function is listed here. More detailed descriptions are given in later subsections below.

ROOT > DATE

"
I could not figure out how to get to the DATE menu.

I hope this explains my difficulty in finding the DDATE function.


Once again, thanks for the great application!
