A7 How do I make my HP49G do this (Rom 1-19.6)? I would like to have it find the derivative of this : 'x^2+y^2=25' Which should be this: '-x/y' I can do DERVX, Y DERIV, {x y} DERIV, etc... and nothing works yet :-( I hope my calculator is not already stumped at chapter 4.8!!! (My mind is still doing quite well, though). 5 I have an application that I'd like to try running on my 48SX. I have a converter box (A) that translates back and forth from a specialized machine-control protocol to plain vanilla RS232 (9600 bps, ASCII). I need to tell this box what I want, listen for the data, crunch it a little bit, and then send the results out to another box (B) at 2400 bps. I only have to be able to transmit to B, and I can easily set it up for real bipolar RS232 or TTL (0v/5v) RS232. The update rate would never be more than 10 Hz, and probably more like 2 to 5 Hz. I have already implemented this on an old Compaq desktop 486 running Linux, and it works, but the desktop is kind of large for the application. What I am thinking of doing is plugging A into the regular serial port, and interfacing B on the IR port. I would have an infrared phototransistor looking at the IR output, buffering it, and driving box B. I have plenty of external power floating around so pull-ups and so on are not a problem. A operates in a polled mode, so I don't have to worry about it wanting to talk at arbitrary times. If I have to, I can turn on the wire serial port, talk to A, listen, turn off the wire serial, turn on the IR, and talk to B. My question - is this possible? Has anyone done this or something like this before? Any links/references to sample code? Than Awesome! Thanks! My two 49's run at 140 and 144 SCR/S. Must have something to do with the fact that my middle battery always dies first. ;-) Hmmmm. . . I swear it did when I tried it a little while ago. And I know it did about a year ago when we were doing stuff like this in school. Strange. . . 2Thank you all.

K&SA from Keyman for the 49 is probably the only tool recalling the standard assignment of all keys including shift-holds (there is some exception known only to J. Busby, R. Hellstern and me :-). This doesn't concern any leftshift key as claimed by you in later mails. Better upgrade first your ROM, because from ROM 19-3 on the structure of UserKeys in the Hidden Dir has irreversibly been changed. That caused certain backward compatibilty problems although ACO tried to avoid them :-) That was appearantly adapted to the 49 long ago by JKH to read also flahspointers, but is obsolate as well from 19-6 on. DType from OT49 (maybe from version 1.2002 on) reads them better... If not, I suggest that somebody else should take this burden from Eric's shoulder. Presently, the 49FAQ are obsolate, and a revision including 19-6 would save a lot of questions and mails in this NG. Unfortunately, an absolutly competent candidat, JHM, was very reluctant in a private mail to me :-) Not at all, I actually would really like so. kalc has its own homepage at http://kalc.sf.net . Oh, I know that very well, and I use Mathematica as a developer and as an end-user every day. Mathematica and the TI-89/92+/HP49G all have their place. I know that TI is targeting the calculators to students and teachers, but I think that is because that market completely overwhelms the professional market (that still does not mean that not many professionals use the TI-89/92+). Yes, but I don't agree that a PDA is a good replacement for a calculator. It is possible that that is the only choice we (power-users) have, and if that is so, I would of course switch. But there is still quite a bit of under-utilized power in the MC68000. Like what? I won't to write a program on my HP48 but the HP 48 make error. The error is behind the else Command. I will make a program that when I press 1 the command for 1 go and then end the program when I press 2 the command for 2 go's and then end.

It's submitted to Erics's site, but you can mail me as usual, if you want it sooner. The most obvious change is the reduction in size, from 10k to 4.2k. The generated code, that can be used in UserRPL programs, is reduced by 60 bytes. Is it possible to use minifont on a inputform? Using System rpl thanks, I've got the INTVX working. Where is this PARTFRAC? Is this part of the new ROM. Also how do you invoke the CASCFG command when it is on the stack. Do you place some info in the () ? larry Just leave it off and cut a mask to cover the naked blue border; it's fast, easy, costs nothing, and looks really good: http://pweb.jps.net/~joehorn/HP49.htm#nowindow The only drawback to this solution is that the *next* time you drop your HP49G really hard like last time, the LCD will crack, since it has SLIGHTLY less structural support when the screen cover is off. As a matter of fact, the size of the extension program will have almost no effect on the speed of it. Copying 200 bytes or 3KB is no big deal. The speed loss will be on the execution itself, not the loading time. The problem with extension programs, is that it is called many times in many different situations. For the help, the procedure of calling the extension message is sligthly different than for other calls. For the APPS menu, the extension messages of all the library installed will be called, therefore if you have a great amount of extension program, it may indeed slow down greatly the HP49. However, for the catalog and the help, only the extension message of the library containing the command will be called, so it won't be too slow. And again, the size of it , will not matter much. In any case, I'm really pleased to see how creative people can be with these extension messages and with the HP49. It's nice to see how your baby can make so many people passionated with it. I'm pretty sure that somebody has explained that already, but I can't find it in google :-/ Anyway, try that example: Pi is the normal Pi on your keyboard :) Open a list and input Pi and press ENTER then 2: { Pi } 1: 3 and do * (multiplication for example) That won't work: Bad Argument Type. But when I have 'Pi' on the stack and put that 'Pi' into a list { 'Pi' } and try to multiplicate the list with 3 I get the desired result. Note the quotation marks. { 'Pi' } dissambles to { SYMBOL xPi ; } while { Pi } will return { xPi } Is this a bug that no SYMBOL is put before the Pi (internally), when I type Pi into an open list. I wonder if Pi = Pi ? ;-) SYMBOL means that one does have an algebraic expression. Isn't Pi in a mathematical sense always an expression and should deserve a SYMBOL in all situations? Thanks Dennis for your explanations! That helped me. That statement is only true for the HP48, isn't it? At least not all of those commands are stable in the HP49, right?!?

I'm having a problem trying to solve the following linear systems in exact mode. The calculator hangs every time and I have to do a warmstart ROM 1.19-6 Its a fairly simple linear systems of equations of the Hilbert matrix Form: A * X=B A=[ [ 1 1/2 1/3 1/4 ] [ 1/2 1/3 1/4 1/5 ] [ 1/3 1/4 1/5 1/6 ] [ 1/4 1/5 1/6 1/7 ]] B=[[1] [0] [0] [0]] I tried this within the Linear System in RS 7. I'll try it again using LINSOLVE but I'll gues it should be the same. Last time I ran it weird things appeared on the screen, it hang pretty bad. I can't reboot, nothing works, what should I do. Can anyone else try it to see if it returns the answer? Try it at your own risk :) The following is the problem and solution as formulated in Mathematica 4.0: In[1]:= m = {{1, 1/2, 1/3, 1/4}, {1/2, 1/3, 1/4, 1/5}, {1/3, 1/4, 1/5, 1/6}, {1/4, 1/5, 1/6, 1/7}}; v = {{1}, {0}, {0}, {0}}; s = LinearSolve[m, v] Out[3]= {{16}, {-120}, {240}, {-140}} Its an interesting matrix, afterwards try it with four-digit precision instead of fractions. See how the answer varies. Any help is appreciated. Thanks, Diego From ???@???

Fri Jan 01 00:00:00 1999 Xref: newsmst01.news.prodigy.com comp.sys.hp48:141468 Without wanting to doubt the beauty in Twains expression, I can hardly let *any* poet, scientist or what so ever, determine my own thoughts about this subject. *I* am the only person who decides what I believe and if I believe. Ditto. Oscar Hammerstein may say what he wants. But this has absolutely no value as an evidence about anything that I want to believe or not. Looks like evolution of belief to me. Which one is the original undistorted form John? The one that you or me accept/want it to be? There are as many original undistorted forms as there are brains on this planet. (Human brains) We unfortunately have no much historical evidence about such forms. Agree, but when their own consiousness comes to play, nobody can tell if this consiousness will lead them to the fundamental source or trick them (us) far away from it. Translation from the mystic: If we all evolved on the same way, then it is reasonable to believe that the same natural phenomenon impressed our species more or less the same way in the past. More or less any human (or pre-human) being was scared from the lightning. Ugh, what is this? Must be God. If this is true then the origins (one of them is fear) of religion were similar and so are the religions themselves similar. Is that what you mean? If religions are cause for so many wars and if religions live within the consiousness and are a product of this consiousness, then for me from the practical point of view, it is no great difference to say the one or the other is faulty. It only brought misery. Heard this many times before. Actually so many times that I start turning red when I hear it again. Until today nothing of this teachings worked. The contrary is the case. We had terrible wars, slaughters, torments etc etc. Even the christian world itself is full of such examples. So from the practical point of view, for me it is about time to say goodbye to religion in the traditional sence. I don't need that. In addition, as said before: I don't take any psalm, or any other human made preaching for the ultimate truth. I don't know if the psalm is right or wrong and as it doesn't give me any means to falsify it, for me it is useless as a source of truth. The psalm may say whatever possible. It would be silly to blindly follow any psalm because it is in one of the old books. There is not much historical evidence about the life of Jesus. Most of the so wanted facts have never been proved. You can hardly call evidence the writings of people that were themselves fans of Jesus. What about the life of Jesus in the Bible is true? What is only added from the writer, who heard that someone heard of something? And what if I don't want to be teached? What if I want to read, say the Bible, myself and find out myself what my version/interpretation of the contents is? It is not an irony, it is a pointer to the (for some people frightening) fact, that you don't necessary need religion to live the good way. Wake up! No heavenly policemen who makes rules for you. You are yourself responsible for the rules, which you believe build a frame, within which you want to live. It works for me. But for me doesn't mean for everybody. You don't seem to realize that there might exist people who dive in the ocean of nightmares instead. It is very easy to say that when speaking for myself. But does it have to hold for everybody? There is not such a thing like win-win solutions on this worls, not because they are impossible, but because the governing individuals don't seem to care about such solutions. And you know, if I come out and scream I bathed in the ocean of peace and found a win-win solution then every government on this earth will certainly stop and ask me what the solution was. ;-) Additionaly: As long we live we have no equilibrium at all. We are perhaps in a stationary state, and this is only an approximation for short observation times. (According to the definitions of physics, that is.) These experiments and the whole brain waves-analogy-rules-bubble-bubble is not a scientific evidence. Give me equations, give me mathematical models, give me strict definitions and *then*, if I don't find any contadictions I *might* accept this is a useable theory, or if I find contadictions or evidence for the theory being false, I will say that the theory must be thrown away. But I will never dare say that this is the truth. Locally perhaps. But globally? (Thermodynamics devils, you know ;-) ) Yes, of course. And through analogy conclusion we have the evidence that this is the way that consiousness can dive in the ocean of peace and find the one and only eternal truth. Exactly like the analogy conclusion of the middle ages, that the world is like a system of crystal spheres. Or the analogy-world-model of ancient Greece, where a stone must fall faster because it is more natural for it to be on the ground, than say for a hair, which must have more air-element in it. Do you imply superconductivity and coherent laser like phenomena in mind? If so, then good luck for you the first time your brain goes superconducting. ;-) Normal infuence of higly accepted and believed people over the mass. Because the mass has is used to believe that most of us don't have the intelligence/capability of finding out our own belief. So we need teachers who know better what is good for us. Of course, if you say so... Ghandi was sleeping much less than other people. According to this theory, he couldn't have been a pacifist. False! I am a restless mind. I find my piece through restless thinking. Your theory doesn't hold. What is the source of mind? What is the evidence for this thus. I can't follow you here. Why does this loss leads to anger, negativity and violence? Where is the evidence for the last sentence? (And I don't mean analogies) The measurements were and are still under strongest critisism. How do you define and measure such things? You are making general rules out of things that might work for you. But you are not the whole world. It is not unachievable utopian vision. It is what a writer wrote, perhaps under the infuence of some kind of grass mixture that he smoked. It helped to have visions, you know. ;-) Why? Because John H. Meyers says so? Where is the evidence? Good old Matt said so. But if we can't prove him right or wrong, then the statement is meaningless. How can I proove if this is true or false? Wishful thinking! Now, what is this kingdom of God? Ask as many people as you want. You will always take a different answer. (Some of them are similar to me) Can this perhaps mean, that the kingdom of God is what everybody thinks that it is? Perhaps it is about time to concern the possibilty that we are not so peaceful as we wish to be. Perhaps we are natural born killers. If so, shouldn't we accept this, before trying to get better? I don't believe any of them. Nonetheless I have no fear and I do not grieve. How comes that? What is true ethics? What is deepest source of consiousness? O me who don't believe. I found my piece when I saw that the construction God is a human made phantom, in order to have someone that dictates rules. So that you can always say: God says so, I am not responsible. I don't need any kind of God. If there is some God around there, well nice to have you around buddy, but I will not cry if you leave. Some sites more for confusing minds and make them obey. What is the source of truth? Your belief about it? Is this that John, or this John? Aah! The first time that you say that this is *your* interpretation. Good to read that. When the Bible (and any other old book) wants you to go to other and say the truth, is this less violent for you? If I live the biblical religion, I shouldn't throw TNT bombs, but word bombs to people that perhaps simply don't want to hear a word about the whole bible. Is this not violence? Agree with you up to the point that religions are interpreted and our actions are based on our judgement. But I react I little allergic to such statements like about what ethics is and what it comes from. If no evidence is available, I can't accept such statements to be true or false. What is eternal justice? What are its principles? What is the proper balance of cultures? What is justice between them? You failed to show me a single thing. You show me only contradictions and tried with the smiling face of an angel to wash my brain beyond recognition. I don't need a single word of all preachers that existed and will exist on this planet (or another) to find my peace. Nobody of them knows what my peace is. My grand father has shown me what is good. My parents have shown me what is good. *I* have shown myself what is good. But all angels and devils and Gods and religions together, have only shown me how rediculous they are. Who slept a couple of hours everyday. ;-) To be simple implies to me to take all complicated phrases of those old books together and throw them away, where they belong. Mighty Gods who failed, and wonders that didn't happen, and angels that tell you how nice the future will be, if you only obey, and all other stories are for me needless garbage. I made my garbage collection before my OS could crash. Again this we! It is not we, it is I! Everyone should be his/her own leader. I don't see why his enlightment is more enlighted than mine. Yes of course. When the Cro-Magnon said to his clan, what he saw and they told it to other clans, this has created no myth? When ancient greeks saw the lightnings above mount Olymp and said this to others and the others added the presence of fear, and the other others added the presence of Zeus with his lightnings in his hands, this was no myth? And it was no myth when Moses took the 10 commands from the hands of God? Human consiousness produces myths since thousends of years. What is the fully enlived Self? Why? We turn them into allegories by accepting that they are allegories, by interpreting them. These analogy conlusions again. Give me a mathematical formula of this and then I may build my opinion. Or else I could also say, something like We should not try to sink to low energy levels, because it is like a particle which can more probably escape potential walls, if it goes to higher energy levels. We will escape our bounds just like particles in the jail of a potential wall, when we go to higher energy levels. Rcobo, give me some real hard laser quants! Such sentences give no criterion for falsification. Are they false? Do they have some resemblance to the real world? Nobody can say. If so, they are not useful for discovery of truth. So you think, Mr. W.B. Yeats. Perhaps so I also think. But can you prove it to someone? Why? Because J.H Meyers wants it so? Yes, who? Of course the same writings don't refer to all cases where this didn't work. The cases where the two women began wrestling against each other when they heard Solomon's words. And who knows? Perhaps Solomon was really a village idiot bureaucrat. This and other myths should I use to make up my mind how I want to live? He could have decided and said anything else. Since he was a VIP he couldn't have done anything but the right thing. If he had ordered to throw all three in jail, this would be also referred to as wise words of the king. Pustekuchen! Is it so important to know that, John? What is a mind which is open to its unmanifest source? What is a mind that is completely awake within itself? As long as you throw such unexplained wise words I'll keep asking you what does all this mean? If silence is a place where I can think without stopping then yes, it works for me. If silence is total absence of any brain activity then no, it doesn't work for me. (Which by nomeans has to be true for any other person.) Greetings, Nick. From ???@???

Read what Thomas says: the *decompiler* shows every 4 bits as a hex character - but of course the grob itself is stored bit per bit. Since for hardware reasons the width of a grob (as *stored*) must be a multiple of 8, a 131*64 grob takes up 136*64/8 = 1088. bytes (the other 10 bytes are used to store the grob prologue, length, width and height, at 2.5 bytes each) of the object that is 2193 bytes large, or roughly twice the size. (it's not because a byte has 256 possible values and a hex digit only 16, that it would take 1/16th of the space ..). If you'd code that string with the full range of ASCII chars io hex digits, you'd end up with a string that is.. roughly the same size as the grob to start with.

KEYEVAL takes a real from the stack and just presses the key that corresponds to this real. The real is constructed as: RowCol.Shiftlevel Row can be from 1 to 10 representing the row of the key. Column can be 1 to 6 representing the column of the key. Shift levels that I know are: 1 Unshifted 2 Left shift 3 Right shift 4 Alpha shift 5 Alpha left shift 6 Alpha right shift 21 Left shift pressed at the same time with another key 31 Right shift pressed at the same time with another key Examples: 82.1 KEYEVAL puts a 4 on your command line, because 4 is the key at row 8 column 2 without shift. 12.21 KEYEVAL (in RPN Mode) starts the PLOT WINDOW - FUNCTION screen because this is key at row 1, column 2 pressed together with left shift. Invoking KEYEVAL more times in programs doesn't always have the results that you may think/wish it should. For example, say you want use keyeval to activate the PLOT WINDOW - FUNCTION screen and then move the selection one field down. The program: won't do that. It shows the input screen but then halts execution until you exit the screen. Then it presses the down arrow key, which corresponds noe to the editor and will take the object on stack level one to the best suitable editor, or will error if the stack is empty. Also doing thins like << 82 KEYEVAL 83 KEYEVAL some other code here Will not put 45 at the command line until the code some other code has finished executing. If some other code contains a HALT, then the number 45 will be put on the command line when the program halts. If a second HALT is in the some other code then the second time the program halts the 45 will be on the stack. If some other code contains an INPUT then at the time where the command INPUT executes the formerly 45 that should be on the command line or the stack simply disappears. Many other strange things with this command but it is useful for automatically activating editors or built-in input screens. Greetings, Nick. From ???@???
