Re: programming HP35s in algebraic mode, please. Message #7 Posted by bill platt on 15 Jan 2011, 6:58 p.m., in response to message #6 by Kip Hopkins
Thank you for your responses. Don't go overboard for me....protect your time, if you need to. But I'm reading and will be trying. At the end of this I will put down the full programs and their intent.
And printing what you've put down and bringing that to my kid's tutor has already gotten me there, undoubtedly. Dieter's post starting: " I'm not sure..." will probably be over my head, but let me address something.
Point #1, On changing modes frequently, I may never go to RPN, again, if I can program and run algebraic and so explaining "RPN resp. ALG" may be time wasted. "resp." may mean respond as, but I don't find that as a button or key.
Point#2: I think that my former small successes in RPN had the display TOP as top of the list. I only will do this one "rake wall" program, so I'm not labeling my program. It sounds like I could leave my great RPN program in there and line one could be that ALG command, but what buttons to push. But...I shouldn't go down that road, huh? I think Dieter's point#1, and line starting "Every program..." is what I need to plod towards. And this guy can help me, I'm sure.
I prefer this as a project with you guys, but I have 4 day blocks off the computer, so don't feel ignored. That "Classic version..and Using equations" almost looks like I could learn that with some quiet hours. Or that guy. Thanks.
Program from "Carpentry Layout", Ken Todd, '88.
I assume ALG.
STO D,
x,
RCL A,
+,
RCL C,
=,
STO E,
RCL D,
x,
RCL B,
=,
STO F
The book leaves out RTN, but I assume it's needed.
And this program needed Height Multipier in MEM A: 2/12=0.1666667, STO A.
And the Rake Multiplier in MEM B: 2 squared + 12 squared=an answer, square root of, /12=1.0137938, STO B.
And the height or length of the first stud...maybe 92.25, STO C.
When out of program mode, put in the short point of the first stud, say 15.25", hit R/S for Run and you get the distance along the rake or hypotenuse. Hit RCL E and you get short point length of that stud.
With a forum's help I think that I learned how to interpret that into RPN. It works for me, but I yearn for the ALG.
So, it's:
STO D,
RCL A,
x,
RCL C,
+,
Enter,
STO E,
RCL D,
RCL B,
x,
Enter,
STO F,
RTN.
And remember that all is over my head and I just need to get the one program in ALG, or, heck, I can always just this last in RPN. Still a good day. Thanks for reading, if nothing else. Right now Carmel Valley is warmer than my house and so I have the doors wide open in January.
