Programming help, please. HP-67 Moving Averages

[Matt Agajanian]

Hello all.

Thanks to Willy Kunz and Cuvee I have HP's golden age on my iPhone

Working with RPN67/97 and RPN-65 has certainly revived my programming intrigue.

Over the last few days, I've been diving into the 67's Standard Pac Moving Averages program.

There seems to be a treasure chest of programming tricks, looping, and indirect addressing genius. I feel overwhelmed trying to mentally grasp each technique.

Has anyone broken down and dissected the program so as to provide a synopsis of what each subroutine does and how the program flows?
I have examined the paper tape TRACE mode to follow the sample exercise. After a while, I get lost on the app's flow.

If I can get a grasp on the programming, indirect addressing, and looping tricks, I can see I'll have quite nifty programming skills to learn about.

Perhaps some folks here can give me a detailed sketch of how the program flows and its indirect addressing tricks.

Thank you in advance
