I'm currently deep in programming my HP35s using the D'Zign Survey Solutions PDF. I started by entering the initial subroutines (LBL A, B, and D I believe) but then began jumping around and entering programs out of order. My focus has been on loading the triangle solutions and a few other programs related to what I’m studying right now. The triangle solution program seems to be working fine, but I'm encountering some errors with a few other programs I entered.
My questions are: does the order in which I enter the programs matter? Can I skip around as needed, or should I follow the order in the D'Zign PDF? Also, does the display order (when I press Left Shift, Down, 2) affect functionality?
The order you enter your programs doesn’t matter. A program calling another program doesn’t care about that. I haven’t done any HP 35s programming in many years. Your best bet is to contact Eddie Shore at the Museum of HP Calculators forums.
Your problem is related to the fact that you don’t have every program in there, or coding errors within those programs. The coding errors can be very hard to spot. Examine the code line-by-line and make sure every character looks exactly the same as the book.
Also, when you examine the program you’re having issues with, you’ll likely see that it’s trying to utilize another program for some sub-function to do what it needs to do.
that “other” program isn’t there in your case.
I know because I’ve done it.
i was in a 4 year apprenticeship and had to program the 35s 5 times now. Drops, batteries, etc…
Just keep that book open on your table with the calculator. And every time you walk by it program a little more. By the end of a day or two it’s done.
@native1 Yep you were right. When I originally posted this I didn't fully understand the programming of the calculator or the D'Zign PDF. But now weeks later, it's fully programmed and I understand how some of the programs use codes from other programs. Works great!
@sonicwave123 Glad it worked out.
I struggled to understand even how to put in certain characters correctly for some time. It's pretty foreign when you first start. Even following some of those programs in the book is challenging to me.
But if you learn inverse, traverse, intersection, triangles, etc. You'll be good to go for the FS exam.
I am no programmer. I see a lot of younger people programming these hp35 S calculators to get ready for the FS exam. I have tutored several people that have had the DZ or other programs and equations placed into the hp that have not been successful on the first or even third attempt. One when I was tutoring him wanted me to show him how to use these equations and programs. I could not because I never used them. I did finally figure out on some problems. But while he was way more intelligent than I am he lacked the understanding of what was being done to solve a problem that required a couple different programs. Like having to inverse between coordinates to get a distance and bearing/azimuth to later compute the coordinates or solve a non right triangle to get that information for an example problem. Make sure you have a thorough understanding of what is being done or needs to be done before learning the program. Programs are great time savors for the exam and for daily production. Just like a data collector or cogo software. I think if one can understand the relationship of right triangles and azimuth to bearing to interior and exterior angles one can almost solve any problem surveying might throw your way. Law of sines and cosines N-2*180. Ratios to percents. Arc formulas. You just about have it whipped.
Well said by OleManRiver,
in my apprenticeship we did it all by hand, and then used the calculator as a check. Knowing your curves, triangles etc is key to figuring things out. Although, I am not sure I could do most of it by hand right now. I should brush back up.
TRY to be a thinker, not a button pusher.
