Need help programming HP-35s

[kjac]

I'm trying to program my new HP-35s with a programing book written back in 2007. I'm not sure if there have been any firmware updates on the calculator since then, so that could be the source of my problem.

My question is in regards to step A013 (as seen in the image below), it calls for pressing the roll down "R↓" key, however when I press that key I get the option to then choose which stack XYZT to use. It then puts REGX, REGY, etc... as the line of code and not "R↓" as shown below. I've tried all 4 stacks and the program still does not work with them. I've also noticed that my calculator puts paraenthesis in after using things like SIN ABS etc... when the program doesn't show them, should they be deleted or does it make no difference?

The program is supposed to convert Azimuths to Bearings and also give the quadrant the bearing is in. If programmed correctly I should get an output of "54.3655" and "2.0000" if the input is "125.2316"
