So I decided I'd finally sit down and teach myself a little calc programming - being as I have plenty of time on my hands. I've had this thing 7 years this month - within 2 weeks to the day. I figured it was time. I watch of lot science shows and they like to talk in metrics. I'm pretty quick at doing a rough estimate in my head when going from feet to meters and vice versa but seem always forget km to miles or back so I figured that would be a nice "program" I could use.
Yeah I could just use the Win8 calculator with built-in conversions for just about everything under the sun - but what the hay.
Seems easy enough. About time huh?
I do have a question: The book says the program space is limited to available memory only. However if I can only name/label my programs as A through Z that limits me 26 programs only regardless of remaining memory.
Am I understanding that correctly?
Guess I'll do a meters to feet next.

International feet or US Survey feet? 😉
From what I recall about the HP33s- yes, you are (unfortunately) limited to 26 programs.
I've been doing a lot of meter to feet conversions and realized I could program my 33s. I programmed the old 48 but we just don't use that one anymore. It was relatively easy on the 33 and even editing an existing one is pretty easy.
Personally, I don't think I can come up with 26 calculations I would like to program. You'd need an index just to keep track of where they're located.

Smarty! That would be US feet. Because I said so.
However, that being said, I am comparing my results to what the Win8 calculator says and using the Hp33 built-in cm-inch conversion.
So I guess the "real" answer would be "depends on what these two devices/programs are using".
Well.... Before replying I did some investigating and come to find out these results are in fact International feet.
Thanks a lot Tom! Now I'm going to question everyone's measurements from here after. I wonder about all my carpenter's tapes and rules now.
Since most of the shows I watch are about astro-physics and cosmology this could be significant. Now I wonder about the speed of light.
Now I'm going to have to compare differences of 299,792.458 km/sec to my long time accepted value of C = 186,282.3970 mi/sec and see how significant that might.
Then again, was a "US mile" or an "International mile" ever established in 1866 or 1950? Suppose I should do some research on the determination of C to begin and see what units they measured in. I'm going to guess metric since most of those "old guys" were NW Europeans.
Fortunately Angstroms (Å) are only based on mm so at least wave-length measurements won't vary.
I can email you a cogo program for this calculator if you like. Send me your contact info and I'll get it out.
Thanks Kevin. Email in my profile should be good.
Anyway,

Thanks, E.
Jacob Wall sent a notice out today regarding a Beta Version 4 COGO+ Pro software of his updated program for a HP 50G.
Look to: http://sgss.ca/

That's a pretty nifty cogo package they have for free. In the event anyone tries it out and their HP50g is not recognized by their desktop here is a link to the usb drivers it needs:
B-)
I have a 35s. I don't know what I was thinking. I was looking right at it when I typed 33s.
At one time Chiefs (and up and coming I-men) from a given community would gather and work through programs for the 11 and 41 series calculators. It was expected that you would have your own tools and know how to use them.
Over the last 15 years or so the local custom is to wait for the boss to pay for someone to learn the limited cogo functions of the Data Collector. Do others see that in your neck of the woods? Does anyone take a plat, house plans and a calculator to the field any more?
Curious, Tom
I still occasionally calculate a lot and house in the DC on the job site. However, my preference is to build the job up in CAD in the office because I find it more efficient and mistakes are easier to spot.
I completely understand the preference. My point is it is rare to find someone who will 'figure it out' when they need to. There are times it would be nice to have the crew return and turn in notes rather than force a return trip so the office can precalc everything. ..
