But; Iıve read some rather heated discussions on a newsgroup focused on email, and I assume the same arguments apply here. The primary concern is that html lows people to do bad things to you when you read their message. Those things appear to range from gathering usage information using something I thiink is cled tracking gifs, getting email addresses for spaming, popups, l the way to instling viruses or damaging Ŝles. These things can happen whether you open the message or have it pre-viewed automaticly. Itıs not so much that the readers think you would put something like that in your messages. Itıs the fact that to read your message the readers must conŜgure their software to low that to happen when reading someone elseıs message with bad stuff in it. If everyone sticks to plain text, the software can be conŜgured to display only plain text. Then micious html canıt cause problems. Itıs just very ugly to try to read. But; anything worth reading will have been sent in plain text anyway, so thereıs no problem. (Well, thatıs the thinking.) So, I thank you too for switching to plain text. However; I have a question for the text based readers. What does Rich Text Format do to you? I assume it is as safe as plain text; but lows some formatting such as bold, underline, and tabs.

Having a morning to kill, Iıve changed FFAC around a bit. 3000! now takes ~8.6 seconds, as opposed to ~336 seconds for the built in routine - this is most 40 times faster then the built in command! Rather then use plain Native Integers, I have used yet another type. For this type, each Œcellı holds a number between 0 and ten thousand. To encode 123,456,789, it would be stored as [1] [2345] [6789] This makes cculations a bit longer, but the display time much quicker. The downside is that the current code only uses 14 bits out of each 32 bit word. 5000! will give the wrong answer, because it uses too much memory. Later on I will pack 2 cells to a word.

Well, the 49G+ has a 75 MHz CPU, not a 4 MHz one - but emulation slows everything down. See my post below for a factori routine thats 40 times the speed of the built in one.

It is inconvenient if the longhold option runs only after the key has been released. I found another simple solution of the problem as follows: If the glob lht isnıt found, Keyman+ uses the default vue 1200 for longhold (just Keymanıs own lib ID, slightly more 49+, Keyman now runs Ŝne without lht, but you may keep is if you want. In the revision so the option key assigment on the keys 0,1,2,3 has been improved. Now you can visit the other ports from inside the browser started with 0,1,2 or 3 longhold. I use these longholds very often since this is faster than Ŝrst launching a Ŝler, and more convenient than setting a port menu anyway. This is helpful only in edit mode. the Credits (together with Jonathan Busby, Carsten Dominik, J.K. Horn and others youıre in an illustrious company as you see :-) BTW, do you know why Keyman got the lib id 1200? Because the re 1200 is in HARDROM and needs only 2.5 bytes instead of 10.5 :-) A note to the question of Tim Wessman. Unfortunately, one cannot have a hard coded variable in a lib and change its vue ad libitum after the lib has been created. A library can only *refer* to a glob which may or may not exist.

I went into META mode after setting the I/0 annunciator with ON_R. META sets it by ROMPTR 6FE 1E (asm) with argument TRUE. But this setting is different. It disappears with a warmstart while the setting with ON_R survives it. Thus, the OS gets confused. META *must* announce its presence in a different way. This is no problem in view of the new header. For instance, by writing META below PRG. BTW, Iım not very pleased with the current design of META. IMHO, too many contra-intuitive and even dispensable keys (e.g., BEGIN END *are* on the keyboard). Who isnıt familiar with GNU EMACS is lost unless he feeds his brain with a lot of contra-intuitive conventions. On the other hand, I miss a tool in META which is basic RPN programming: A key which, if the cursor is put on an gebraics, replaces it by its RPN equivent. Thus, it does ->RPN, but on a more elaborated level as the meanwhile forgotten TEACH from the HP48. === Subject: New Binary Features In my usage of my HP49G in various computer classes, Iıve come upon a few shortcomings that I wouldnıt mind seeing Ŝxed in a future cculator or Ŝrmware.

So the computer thinks about a 4 number code and the user should guess it. Now Iıve come to a cruci problem: The white pawns. They tell the user how many digits of the code were right but not on the right place. But itıs so lowed to guess one number more than once since the code so can contain each number more than once. So what I have is this: << 1 4 start rnd 10 * ip r->i next 4 ->list -> tk < 4 ->list -> uk << tk uk << == >> dolist << + >> stream -> black << 1 4 for l1 1 4 for l2 if Œtk(l1)==uk(l2)ı then if Œl1<>l2ı *** <> = not equs then 1 else 0 end else 0 end next 4 ->list << or >> stream next + + + White swap Black black >> >> This code works perfectly as long as the secret code doesnıt contain more than once the same number and the number entered by the user so not. It prints: White 2 Black 1 for example. As soon as the codes contain double numbers, the black number will ways be correct, but the white wonıt no longer. That is to say, in this form, the user has only one chance of course, I must put the whole thing in a loop until Black = 4. The question is: Is there a function in the HP 49G+ that can tell me the differences of two list or the similarities? So that you enter two list and the cc tells me which elements of both lists are equ? It must be possible to write a much shorter and more elegant program. I donıt know l the functions of usrrpl yet.

Or have I misunderstood your reference? Yes, thatıs the one, and the best connectivity kit Iıve yet seen by the way. Even though it uses the Xmodem protocol, it has a text option similar to the HP cculator Kermit ASCII transfer option, but better. For example, you can disable translation of Line Feeds independently of the non-ASCII translations, and so optionly translate the other ASCII control codes 0-9, 11-31, and 127 to the nnn translation codes. And you can open a Cculator Commands window to execute commands on the cculator itself from the PC, similar to using Remote Host with Kermit. And the built-in translations for Kermit have a bug in my opinion. The sequence is sent from the cculator unchanged, but when itıs received on the cculator, itıs translated to just . Itıs been that way since the 48SX, and Iıve learned to work around it for the rather rare times that I actuly do want a liter in a string. With Conn4x, the sequence is sent (assuming that the option Add CR to Line Feeds is checked) as , so as long as you can keep your text editor from correcting this, itıs changed back to the origin when the Ŝle is transferred back to the cculator. Note that Conn4x so works with the 49G. It works with the 48G seriesı built-in XSEND and XRECV commands, and by adding the XSrvr library, you get the full functionity.

Well, the busy and I/O activity annunciators do turn on for a while if you try to print with that ŝag combination, so maybe itıs going out the USB port. But I donıt know much about USB. I wonder whether thereıs a termin emulator that recognizes USB as a vid port, or some sort of software that can take I/O from the USB port and present it to HyperTermin as a COM port. With the other cculators, I can print to HyperTermin.

So the decompilation/compilation is done on the cculator, and the text translations on the PC. That makes sense to me; itıs probably faster, and translations on the cculator might have a problem under low memory conditions. And apparently Conn4x makes some temporary mode changes on the cculator. > The translations are multi-stage because of PC Ŝle name > limitations.

I was aware of speci translations for Ŝle names, but rely havenıt looked into it; Iım pretty conservative on variable and Ŝle names. I suppose that we have to use vid variable names on the cculator for Conn4x to get it right? By using the S~N command, I can get some rely silly names, and even use style and font changes so the name has a bunch of ASCII control codes in it. > Your earlier comment about the 48G is true.

Much as I like Conn4x, I hope that itıs still a work in progress; there are some things Iıd wish for. For a start, have it remember whether it was last in text mode or binary mode; if I disconnect, it ways goes back to binary, even without exiting the application. It would be nice to be able to transfer to/from the ports too, instead of just HOME and its subdirectories. And using Edit as text leaves the Ŝle in my Windows temporary folder; itıs not a big de, but shouldnıt Conn4x delete the temporary Ŝle?

It has been years since I last had a crash with my TI89 - not counting when I run asm apps without the necessary TSRs or similar. To compare I have a solid freeze (batteries out) roughly once a month with my HP49G+.

Note that for Conn4x to work, ŝag -33 must be clear (Transfer via wire), and for Conn4xıs Screen Capture to so work, ŝag -34 must be set (Print via wire). To use the Screen Capture involves Conn4x disconnecting (that is, telling the cculator to exit Xmodem Server), and then the user does the PRLCD hidden key combination (On and Cursor-Up together on the 49g+). Note that the Connect using: must be a speciŜc port (such as HPx9g+) for this; Auto wonıt work. So apparently the 49g+ does indeed print via USB, and Conn4x captures the print data stream and builds the graphic screen display based on it. Note that if you use some other print command or XMIT, then Conn4xıs Screen Capture will give you a Read Error. === Subject: Re: HP 49G+: Are The Bugs Worked Out Yet?

I want to plot a straight line so I have to apply natur logarithms to my origin raw data which I previously saved as an array on the 49G.

I only started trying to learn how to program the 49G about 2 weeks ago and I am following the userıs manu. I have done the Pythagoras program that the manu teaches. In the manu they only teach how to implement the program in gebraic mode but I follow l the lines (in gebraic mode) and when I press Enter to store the program the message Invid Syntax appears. If I implement the program in RPN and put it on the stack, type a name and so put it on the stack and then press STO> nothing wrong happens and the program is stored. So, though the manu only teaches the program in gebaric mode, the only way I am able to store it is in RPN (what where the people who made the manu thinking?) But the funniest thing is yet to come. I can only run the program in gebaric mode in the way that manu teachs (not everything is worng after l). But gebraic mode is something that shouldnıt even be present in this cculator in the 1st place so I donıt want to switch modes everytime I want to run a program. Can anyone tell me how to run a program in RPN? Recling other opps in RPN I guessed that I would introduce the arguments of the program in() and separated by comas, press enter to put it on the stack and then press the respectiv function key to run the prog but the Too Few Arugments message appears. === Subject: Re: Please!

I couldnıt use the origin version of Conn4x, but now it works perfectly for me, as far as Iıve noticed. Iım still using MS Windows 98SE; maybe that makes a difference. For now, assuming that the Ŝle is stored as a string exactly as you previously posted, try the following: Make sure that the cculator is in exact mode if you want the exact integers to stay that way, otherwise be in approximate mode to have them treated as re numbers. Set other modes as indicated by the ASCII transfer header: Execute 3 TRANSIO if youıre not certain that youıre in that translation mode. Execute DEG if needed to set the angular units display. You need the . as your fraction mark; change the mode if needed. Well, actuly, those last two donıt rely matter for that particular program now that I look at it a little closer. Now edit out the %%HP: T(3)A(D)F(.); ASCII transfer header. With the string on level 1, execute: # 2F34Dh SYSEV to convert the translation codes to characters. Execute STR-> to compile the string to a program object.

There are lots of SysRPL commands for text processing in Carstenıs data base, but only the command Put_Style (dangerous bang type) concerns styling. Now, producing stylings is no problem with Style from the edit menu. The problem is recognizing and isolating styled words or phrases by a program. A cruci command, cl it UNDERLINED? should work as illustrated by the stack diagram where $ denotes any, perhaps styled string: $ ---> $ı TRUE (where $ı is the 1st underlined word or phrase in $) $ ---> FSE (if no word is underlined in $ $ı should appear on the stack without its styling. Are you or is anybody else able to write such a command? Thatıs shouldnıt be very hard, but I have to time to investigate in detail which control charaacters are used at which position. It seems plausible that the lenght of an underlined phrase is coded itself by a character so that a styled phrase can have at most lenght 128. But I may be wrong. It would be nice giving me one or two nice examples, indicating precisely the positions of which control character. I guess this is l the same for current font or minifont though in minifont only the stylings ITIC and UNDERLINE seem to work. That would be sufŜcient for me, the rest I do in SysRPL by myself, in particular recursive search. The string anysis has probably to be done on a PC. It may be much harder to make the control characters visible on the 49+. Perhaps somebody did this ready and I missed it. === Subject: Re: HP49: Flag -87 (a detailed -87 ŝag explanation) What I see!

Since the cculatorıs XRECV command didnıt recognize your Ŝle as a vid binary transfer, it just stored it as a character string. Since Xmodem server isnıt built-in on the 48G series, an Xmodem Server library for the 48G is included in the connectivity package with Conn4x. But how to transfer the library to the 48G in the Ŝrst place? Conn4x includes the ability to send a binary Ŝle and have the cculator receive it with the XRECV command. And since some users may choose not to instl the Xmodem library, Conn4x can so receive binary Ŝles sent from the cculator with the XSEND command, so itıs still useful with the 48G series even without the Xmodem server library . XSEND sends in Xmodem binary mode only, much like the SEND command for Kermit when in binary transfer mode. The Ŝle transfer protocols for arranging for a Ŝlename, breaking the data into packets, sending it, verifying that itıs been received correctly, and putting the packets back together are different, but the Ŝle data into and out of the Ŝle transfer protocols themselves is the same for Xmodem and Kermit binary transfers. For either Xmodem or Kermit binary transfers from the cculator, the Ŝle data starts with a binary transfer header, HPHP4n-x (where n is the character 8 for a 48 series, and 9 for a 49 series; is the ROM version letter, or for a Ŝle that the 49g+ stores on an SD card). Following the binary transfer header is the compiled object itself. XRECV (not built-in on the 48SX/S) is the built-in command for receiving an Xmodem transfer on a 48G series or 49 series cculator (RECV is the similar Kermit command). Unlike RECV, XRECV doesnıt know anything about ASCII Ŝle transfers. It looks for a vid binary transfer header (HPHP49-x on a 49 series and HPHP48-x on a 48G series), and then a vid compiled object immediately following. Iım not sure how thoroughly it checks the vidity of the compiled object. If both conditions are met, it stores the compiled object as received; it doesnıt do any translation or compilation. But if either requirement is not met, it protects the memory structure and operating system by storing the entire data stream as a character string. That is, it stores it with the character string prologue, a size Ŝeld with a vue corresponding to the number of bytes received, and Ŝnly the actu data bytes as received (still no translation or compilation). Since your Ŝle started with an ASCII transfer header, XRECV quite properly didnıt recognize it as a vid transfer, so stored it as a character string. Of course, binary transfers between the 48 and 49 series may well be incompatible because of changed entry points and new object types in the 49 series, so l transfers with the wrong binary transfer header are so considered to be invid, and stored as character strings. I wish that theyıd included an ASCII capability (decompiled object, optionly translated Line Feeds and non-ASCII characters, ASCII Ŝle transfer header) when they implemented Xmodem transfers with the 48G series, but they didnıt. I suppose that they intended Xmodem for higher speed, and the decompilation/compilation and translations do short and ROM is full. in response to a Why donıt you... type question. XSEND and XRECV do binary transfers, regardless of the state of ŝag -35 (ASCII transfer / Binary transfer). The 49G adds a built-in Xmodem Server mode similar to the Kermit Server mode. In Server modes, the cculator is controlled by the client at the other end of the connection. But this still doesnıt quite implement ASCII transfers; the Xmodem transfers are still binary only. If you want the object decompiled/compiled and optionly translated, you have to do that separately. Conn4x uses the built-in Xmodem Server on the 49 series, or an added-in Xmodem Server library on the 48G series, to control the cculator when connected. Of course, Conn4x (or any other client) canıt actuly put the cculator into Server mode, it can only check that thereıs a cculator thatıs ready in Xmodem Server mode at the other end of the connection, and then control the cculator if it Ŝnds this to be so. The Conn4x version on the CD-ROM does only binary transfers, but more recent versions of Conn4x add the Text modes. In text modes, Conn4x tells the cculator to compile/decompile objects as appropriate, and optionly translates Line Feeds, l other ASCII control codes, and some or l non-ASCII characters. so, it builds a text transfer header based on itıs chosen translation option and the cculatorıs current modes for transfers from the cculator, and uses the header (if present) to determine how to do the reverse translation and temporarily force the modes on the cculator while compiling for transfers to the cculator. Kermit transfers use the built-in SysRPL commands KVISLF and KINVIS on the cculator to do the translations, but Conn4x does the translations itself, on the PC. For Conn4x to do the compilation/decompilation itself instead of having the cculator do it, it would probably have to be practicly an emulator for the particular cculator that it was connected to. That wouldnıt be entirely impossible, but certainly more difŜcult and complicated. On the other hand, character translations are relatively simple, and probably faster on the PC than could be achieved on the cculators. As long as the Ŝle is used on the same cculator, it works well. But the 48 series and 49 series do differ in the way that they decompile/compile the null character, double quotation mark, and backslash characters, so text Ŝles from one series of cculator may not be translated and compiled correctly for the other series, even if everything else is compatible. You may need to do your own modiŜcations of the null character and backslash character translations to get them right, and for double-quotes within strings, resort to a bit of trickery. This applies to both Kermit ASCII and Conn4x text transfers. so note that Conn4x and Kermit differ in the way that they translate those same three characters, so you may have to modify them yourself to use the other transfer method with a Ŝle on your PC. === Subject: Re: there is a User guide for the 49G in RPN mode???? > I kept l of my old 49g/g+ manus, but the only one Iıve ever actuly used > was the little reference book that came with the 49g.

Are you or is anybody > else able to write such a command? Itıs certainly possible. Is underlining the only style that youıre interested in? Iıd understand word to be a sequence of characters up to the next separator or delimiter, but what do you mean by phrase? Perhaps easiest to return $ı as the entire underlined text. What about strings that contain control codes? In particular, what about the speci case of <3> by itself between style or font change sequences? Ok, the following program takes any string as an argument, and if it doesnıt contain any underlined text, then returns the re number zero. In the case that the string contains underlined text with both beginning and ending underlining delimiter sequences (the norm case for styles), it returns the text (without underlining, but with any other style/font delimiters that it happened to contain) that was between them on level 2 and the re number one on level 1. Note that the returned string may contain unmatched style/font delimiter sequences. If it contains underlined text but lacks the matching ending delimiter, then it returns the text up to the end of the string on level 2 and the re number one on level 1. Again the string may contain other, perhaps unmatched, style/font delimiter sequences. In the case that the string has an unmatched underlining delimiter sequence at the end of the string, it returns an empty string on level 2 and the re number one on level one. In the case that the string has <3> as the only character between style/font delimiter sequences, that will be incorrectly treated as an underlining delimiter sequence, unless it occurs after two such sequences. See below. > Thatıs shouldnıt be very hard, but I > have to time to investigate in detail which control charaacters are used > at which position. It seems plausible that the lenght of an underlined > phrase is coded itself by a character so that a styled phrase can have > at most lenght 128. But I may be wrong. No, the styles and font changes are delimited by sequences at both ends of the text that they apply to, so they can be of whatever length you can manage to Ŝt into memory. The same sequence is used to start and end a style. If you use the Style menu keys to make the font changes and styles from the editor, then any missing closing delimiters are added automaticly at the end of the string, but if you add the sequences yourself (using the CHR and + commands or writing a Ŝle on the PC, for example), or use SUB to extract a substring, you can have a string with an unmatched delimiter sequence, and the style applies to the rest of the object, including the rest of a composite. I expected styles to be for strings only, but you can easily change a string to a name with the S~N command, in which case the hidden characters are indeed in the name, and the name is displayed in that style. The style codes are as follows: <19><1><19>bold<19><1><19> <19><2><19>itic<19><2><19> <19><3><19>underline<19><3><19> <19><4><19>inverse<19><4><19> You can apply more than one style to the same text, for example: <19><2><19><19><3><19>itic and underlined<19><2><19><19><3><19> or: <19><2><19>itic<19><3><19>itic and underlined<19><2><19><19><3><19> Font change codes are similar, but have two such sequences at each end of the text that they apply to. First, for the font thatıs being left and then for the font that being started. And the vue of the code between the <19>s isnıt the font ID number itself, but the font ID number plus 11. This avoids the complication of a null character, duplicating the style change codes, and having a Line Feed control code in the sequence. For example: <19><11><19><19><13><19>text in font ID two <19><13><19><19><15><19>text in font ID four<19><15><19><19><11><19> What happens if I build a font change sequence using the vues 0, 5-10, or for that matter, for a font that I donıt have on the cculator, I havenıt experimented with. I havenıt experimented with unmatched font delimiters either. Simply looking for a style sequence with POS doesnıt quite do it, because the same sequence is used to end a style as is used to start a style. The Ŝrst occurrence turns a style on, the next turns a style off, the next back on, and so forth. The program that I posted in an earlier thread (see works in most cases, but fails for certain speci cases. For example, suppose that I have a single ASCII control code 1 between the style delimiter sequences for underline, like this: <19><3><19><1><19><3><19> My program Ŝnds the <19><1><19> substring, and incorrectly decides that itıs a bold style delimiter, and then when it looks for <19><3><19> style delimiters, theyıve ready been changed. Okay, itıs not very likely that one would put a single control code 1-4 between style or font changes, but suppose that I extend this to looking for font changes, where the code could be any vue from 11 through 255. You could very well have a single character between font or style changes, so simply sequentily searching for l of the various possible sequences may very well fail, besides being slow. I could write a UserRPL program that looks for the Ŝrst occurrence of <19> and then checks that thereıs actuly another <19> at that position plus 2, and if so extract the character between them and determine what it means in terms of font changes or styles and look at the rest of the string for a matching delimiter. Idely, Iıd use a search command that lows wildcards or regular expressions, but I donıt think that either user or system RPL provides such a command, though I understand that EMACS can do regular expression searches. I wonder whether anyone has written a stand-one program for these more sophisticated searches. > It would be nice giving me one or two nice examples, indicating > precisely the positions of which control character.

INVERSE works in the minifont too, but indeed BOLD doesnıt seem to have any effect in the minifont. The styles apply to user-deŜned fonts too, not just the built-in fonts.

It transfers the Ŝle ONLY in a text > format (quote delimiters). I understand that. When you use the method, Conn4x recognizes the vid text transfer header and so treats it as a text Ŝle; that is, Conn4x does the translations, tells the cculator what the angular display unit and fraction mark should be, and has the cculator (try to) compile everything after the header to a program object and store it as a compiled object, a program in this case. But when you use the FILE | Download (Manu XRECV) method, itıs sent as a binary transfer, that is, with no translation and the cculator doesnıt compile it, and since it doesnıt have a vid binary transfer header (or a vid compiled object, for that matter), XRECV converts the entire data stream to a character string object before storing it, and when you recl it to the stack, it should look very much like it did on the PC, except that youıll very likely (depending on how it was stored on the PC) see a little black square at the end of each line that represents a Carriage Return control code, and it will be displayed with the character string delimiters. If the Ŝle had been transferred from a 49 series to the PC in binary mode, assuming that no editing was done to it, it wouldıve had a vid binary transfer header followed by a vid compiled object, so XRECV wouldıve just stored the compiled object that it found in the transfer, instead of converting the entire Ŝle transfer data stream into a character string. Perhaps the reason for this misunderstanding is that maybe you donıt reize that when you look at an object on the cculatorıs display or transfer it with a text transfer and view it with a text editor, what youıre actuly seeing is a decompiled representation of the object, not the compiled object as itıs actuly stored in memory. If you care to see an object as itıs stored in memory (but represented as characters instead of nibbles or bits), transfer it to the PC with a binary transfer, view it with a text editor, and ignore the Ŝrst eight characters (the binary transfer header). Character string objects, after the Ŝrst Ŝve characters (prologue and size Ŝeld), will look similar, except for style and font change codes (normly hidden on the cculator), the delimiters that the cculator adds when decompiling arenıt actuly part of the object, and very likely a different character set will be used for control codes and non-ASCII characters. Names are stored using a scheme very similar to that used for characters strings, but since the prologue + size Ŝeld uses 3.5 bytes, the characters displayed in the text Ŝle are hf of one character in the name and hf of another; good luck deciphering that. Other types of objects will look very different. > This is l okay, as long as it is the consistant way things must be > done. Iıll simply note in my manu that program transfers have to be > made while connected using the right shift THEN right arrow scheme. As long as you have a 49 series cculator, or a 48G series with the Xmodem Server ready instled, Iıd suggest ways putting the cculator into Xmodem Server mode and then telling Conn4x to connect. Donıt bother using XRECV. When you want to transfer an object from the cculator in the decompiled, translated form for easily understandable viewing or editing, use text mode, that is, click on the little 010101 box to change it to ABCD. But if you just want to store the object on the PC for safekeeping, or as a step in transferring it to another cculator of the same series, the binary transfer is faster, though itıs not easily readable by ordinary humans, and successfully editing it would be difŜcult, to put it mildly. The Ŝle size is smler too, though with the large cluster sizes on hard disks, that wonıt matter for most objects. For storing on a ŝoppy disk with smler clusters, the Ŝle size may make a difference for fairly large objects. For transfers back to the cculator, as long as the Ŝle has a vid transfer header, you donıt have to tell Conn4x whether to use a text or binary transfer; in fact, Conn4x will ignore what youıve chosen and use the transfer header to determine how to handle it. But a disadvantage to using text mode is that if the cculator happens to be in approximate mode when it receives a text transfer, any exact integers (type 28) will be changed to re numbers (type 0). Generly, if the Ŝle started out on a 49 series, youıll want to be in exact mode, but if the Ŝle started out on a 48 series, youıll want to be in approximate mode so that any res that have integer vues (and no decim point) wonıt be changed to exact integers. Vectors and complex numbers are ways stored in rectangular coordinates, but when in cylindric or spheric display mode, theyıre decompiled with polar coordinates for stack display, editing in the command line editor, and text mode transfers. If you have the cculator in cylindric or spheric display mode, and you transfer a vector or complex number from the cculator in text mode, and then transfer it back to the cculator, it may be stored as a slightly different vector or complex number, though it will look the same in the origin cylindric or spheric display mode. The same thing can happen when you use EDIT to decompile it to the command line editor, donıt explicitly make any changes, and then press ENTER to compile it. An easy example of the this is: Execute (1 1) DUP CYLIN EDIT, then press the ENTER key and execute RECT. Thatıs not to say that you should never edit or do a text transfer in cylindric or spheric display mode. If the polar coordinates are particularly important to you, then use one of the polar coordinates display modes. If the rectangular coordinate vues are especily important, then use the rectangular coordinates display mode. And be aware that a slight inadvertent change is possible when you use polar coordinates. > I donıt understand why the File | Download (most obvious choice) is > even there. The best reason for it being there is that the 48G series doesnıt have a built-in Xmodem Server, but perhaps so for use by users who are ready familiar with XSEND and XRECV, but not familiar with Conn4x. Note that once you tell Conn4x to connect and itıs detected that a cculator in Xmodem server mode is actuly at the other end of the USB cable, that option is greyed out. > One thing for sure though, and Bill hit on it, is that I need more > experience with this to get fully up to speed. Iıll have to learn > what the limitations are on the two methods, then which method to use > should become clear(er). Just use the Xmodem Server and then Connect method, and for transfers from the cculator, choose whether to use a binary transfer or a text transfer. This is probably easier than using the XSEND and XRECV commands, and lows you to use text mode transfers, a must for viewing or editing the Ŝle on the PC.

The Ŝles were there but it didnıt know what to make of the Ŝles and listed the Ŝles as being text and added ... to the beginning of each Ŝle name. As a further test I copied a library from port 2 to a newly formatted card and compared it to the same library I saved from an SD card prior to the upgrade. They were different. In my case l I had on the card were backups of select objects in port 2. Since port 2 was preserved during the upgrade nothing was lost. Has anyone else seen this?

Of course, if youıre writing a Ŝle in a text editor on a PC, you should include a header similar to this. It tells the cculator, for Kermit transfers, or Conn4x if youıre using it for Xmodem transfers, Ŝrst, that itıs an ASCII (Text) Ŝle that needs to be compiled. The T(3) indicates which Translation codes should be converted to characters; the possibilities are 0, 1, 2, or 3. A 0 means no translations, and a 3 includes l available translations, at least for Kermit. Conn4x has a few more possibilities than Kermit, and Iım not entirely certain how it handles the various possibilities with just four available numbers for the header. See Text Files, Text Options in the Conn4x Help Ŝle or TRANSIO in your cculator manu. If you have a 48 series, chapter 33 (48SX/S), or chapter 27 (48G series) explains it reasonably well. A(D) indicates that any Angular vues (indicated by being preceded by the angle symbol) found in complex numbers or vectors are in Degrees. The other possibilities are R for Radians or G for Gradians. F(.) indicates that the period is the Fraction mark (and the comma is a separator). The other possibility is F(,), in which case the comma would be the Fraction mark, and the period would be a separator. At least for Kermit, you can have the above three parameters in any order, or you can leave out any of them, in which case the cculator uses the current mode for that parameter. For example, if the header is just: %%HP: ; Then it tells the cculator that the Ŝle is an ASCII transfer that need to be compiled, but not which modes to use, so the cculator just uses the current modes when it translates and compiles the transfer. I donıt know whether or not Conn4x is as liber with what you can use for a header. === Subject: Re: NCEES bans certain cculators from test sites > Additionly, you can purchase older HPıs, like 41C and 41CV, which I > believe but not sure that are still permitted without the modules of > course, at pawn shops and on ebay perhaps for less than or around $40. > For that price, one should get an extra one as a backup just in case > something goes wrong with the primary one.

As far as Iıve noticed, the built-in compiler for the command line by pressing ENTER compiles to US just Ŝne. I wonder what you could be doing differently from the way that I do it. For anyone new to this discussion, weıre cling the string with only the sequence ASCII control codes 19, 3, 19 (decim) US, for Underline String. Another part of this discussion is in a thread named Identifying styled words by a program; see: For a start, when Iım playing with a cculator at home, many of my programs are written with a text editor on the PC, so I may well fail to even notice strange things that happen with the command line, or attach due importance to them even if I do notice. When I post source code complete with a transfer header, my gener expectation is that for l but short, easy to key in code, most of those who care to try it out (if anyone does) will simply copy and paste it to a Ŝle, and download it to the cculator, rather than going to the bother of keying it in to the command line. Of course I reize that this isnıt ways the most convenient or even possible method, and the source code could be corrupted somewhere ong the way, so I try to remember to insert the checksum and size as comments, even if I donıt usuly bother to otherwise comment the source code. I do download the source to my cculator and try it out before I copy and paste it into my text editor for posting, so I can easily enough run BYTES on the object while Iım at it. Of course, if someone does key it into the command line, the header indicates the translation mode, angular units display, and fraction mark. To prevent corruption and ensure that the reader sees the same printable ASCII-only characters that I see, I ways use translation mode 3, and additionly use nnn translation codes for any control codes. Unfortunately, with the program I posted, keying it into the command line isnıt quite so simple as one might at Ŝrst suppose. Sometimes that happens when I write something something thatıs rather unusu, particularly with control codes, liter double-quotation marks, or liter backslashes. Sometimes I choose to use a counted string instead of a delimited string. And sometimes transferring into a cculator changes a liter CRLF pair to just LF, and a text editor may well tamper with Tabs, Line Feeds, Carriage Returns, trailing white space on a line, or even repeated spaces. I suppose that I should be more careful to point out such possible difŜculties. But anyway, yes, the command line editor does seem to expect the font changes and styles to be inserted into a string by using the Style menu keys, and using that method, it seems to automaticly add any missing matching style codes as soon as I move the cursor past the stringıs closing delimiter. This seems perfectly reasonable to me; itıs much like the compiler sometimes silently assuming closing delimiters if I donıt have them in the command line or whatever else Iım asking it to compile. The ternative for a compiler would be to issue some sort of error, presumably the ways helpful Invid Syntax. What should the editor do for missing style codes? As far as Iıve noticed, using the Style menu keys, if I donıt have at least one displayable character after opening a style before closing the style or ending the string, the style code isnıt in the string. Surely thatıs reasonable? Right offhand, for ordinary purposes, a pair of matched style codes with nothing displayed between them would seem to me to be a pure waste of memory. Okay, on the system level, the OS just might have a need for them, but on the user level, since they never (normly) occur, why would I ever want to search for them? Of course I can make a such a string by having US on the stack, doing DUP and then +, but I wouldnıt cl that norm. Quite apparently, to get a string like US into the command line, I have to use something other than the standard method of using the Style menu keys. I can build up such a string out of parts easily enough, or use SUB to extract it from a norm underlined string, leave it on the stack, and then echo it into the command line wherever I choose to. My usu method of getting ASCII control codes (or anything I donıt remember a key for) into the command line is to simply use the character browser (or my own menu designed for this on the 48SX). But this behaves a bit unusuly for US. Try this: Open a command line with the delimiters, then open the character browser, echo in the characters for ASCII 19, 3, and 19, and then close the character browser. The command line looks strange, and if you continue keying in, things get even stranger. But if you press ENTER immediately after closing the character browser, the string goes on the stack, looking like the empty string, except that editing with US in the command line just Ŝne, with US still looking like an empty string, except with an underline under the closing delimiter, and extending until the next time that US occurs. And when I press ENTER, whatever I have on the command line is compiled just Ŝne, as long as I donıt have any syntax errors in it. I just now discovered that if I accidently use EDITB instead of EDIT, the US does indeed become the empty string. Perhaps thatıs what youıre doing differently? But if US is ready an element of a composite, itıs left as is, even with EDITB. Except that the display is rather strange, I donıt see any problem with using the command line editor with a string that ready contains an unmatched style code, and pressing ENTER compiles the object just as I expected. handles strings with unmatched style codes? Iıd have to say that indeed it is, but I can live with that. And strings (and composites that contain them) with unmatched style codes are displayed rather strangely, so perhaps we could say that the display routines are buggy. But after l, the intention is apparently that style/font codes are present only in matched pairs in the same string, and weıre doing something that apparently wasnıt anticipated by the developers. If thereıs a bug, one might think that the re underlying bug is that we can even manage to have a string with an unmatched style code at l. But surely a character string must be able to contain absolutely any sequence of characters at l. Suppose that I want this sequence in a column graphics sequence that Iım sending to the 82240A/B printer? Or in an escape sequence to be sent to an Epson or some other printer? And weıve found some other uses for US. The ability to have any sequence of characters in a string is much too important for it to be changed, even if certain sequences do change the way the string is displayed. So in my opinion it rely is the command line editorıs handling of US thatıs buggy, ong with the display routines. Things could be set up so that a style isnıt displayed past the end of a string, or perhaps not used at l if the matching style code isnıt in the string. And since the string can be changed to a name easily enough, the same would apply to names. In any case, I can easily live with the way the cculator works with US now. Iıve never had US or the like cause a hang, warmstart, or TTRM, so I canıt consider the way the cculator handles it to be a serious bug. Is MASD buggy in that it wonıt compile to an object that has an unmatched style code? Well, since the UserRPL compilers can do so, and in my opinion, absolutely any character string must be lowed, I suppose that it is, but apparently this is an unexpected condition, and Iıd Ŝnd it hard to put too much blame its developers for this. Quite apart from the above, in my opinion using ASCII 19 in the style and font codes is a very unfortunate choice, as itıs the code used for XOFF. Perhaps if ASCII 19 (and 17, XON) werenıt ordinarily used for anything in the 49 series, XON/XOFF ŝow control wouldnıt have had to be broken in the 49G. But thereıs at least one very important person who just doesnıt seem to understand how very important XON/XOFF rely is for ordinary seri communications without some other speci protocol in the 48 series anyway. === Subject: Re: Identifying styled words by a program > Would be nice if you list them with their stack diagrams. This canıt be > that much. I donıt Ŝnd anything helpful in Carstenıs data base :-) Most of the SysRPL commands are working directly in the command line. Style in independant strings hasnıt rely been implemented/Ŝnished. Playing with styles and so on can create huge strings. when you vidate the command line with ENTER ; the string is anysed and l useless code that have been inserted are removed to make the string as sml as possible. Basicly the different options possibles are: -Putting the command line cursor at a given position. This position can be deŜned in two modes: The physic location (basicly the characted numbers including style changing characters) or the *visible* position: what you actuly see ; e.g. the 3rd visible characters) STO_CURS_POS / STO_CURS_POS_VIS -Retrieve the cursor position. Again two possibilities: either you get the re position, or the visible position. C_CURS_POS / C_CURS_POS_VIS The command names between the two modes are usuly the same except that _VIS is added to the name when working in *visible* mode. -Adding text: CMD_PLUS : will add text/character at the current cursor position. Do not take care of style: e.g keep the current style PASTE.EXT: This will take care of l styles to make sure everything stays coherent. Used by the PASTE command ; if you *paste* a text without any attributes in let say bold ; control-characters will be added around so the added text is not in bold etc.. -Deleting text CMD_CUT (warning, unlike what the name says: it actuly deletes) -To extract selected text into the stack (and make sure styles are kept) CMD_COPY.SBR The position of the cursor will be changed.

Of course itıs possible to re-instl 1.18, though I suppose that it may be necessary to erase that extra ŝash bank that 1.19-6 uses as part of the process, just like you erased it when upgrading from 1.18 to 1.19-6. But whatever the problem with your cculator is, that behaviour certainly isnıt norm for 1.19-6, and the bug Ŝxes and enhancements in 1.19-6 are well worth having. It could be that some library you have instled isnıt compatible with the upgraded ROM. Iıd suggest Ŝrst bypassing the library conŜguration routines by holding down backspace through a warmstart. Perhaps the surest way to do this is use ON&D to go to the Tests screen (the Ŝrst one you used when upgrading the ROM), holding down backspace, and pressing Q for Reboot. If you press RightShift LIB (on the [2] key) after that, you shouldnıt have any libraries in the menu; just the port menu keys [ :1: ], [ :2: ], and [ :3: ]. If that Ŝxes it, itıs a process of Ŝnding out which library is causing the problem. Perhaps just attach them one at a time until the problem comes back. If that doesnıt Ŝx it, Iıd trying re-instling 1.19-6. Or perhaps copying everything that you want to keep from the HOME directory and port 0 to port 2 or a PC, and then doing an ON&A&F memory clear, and see if that Ŝxes the problem. Please let us know how it goes. === Subject: Re: Program Editor?

But, with is not any different from other laws we de with on daily basis. The laws come in effect based on conduct of a few dimwits who abuse the system and destroy it for others. You think people like to wait to be screened at airports? Or, the guy who had a few beers with his dinner being arrested since his blood cohol content was a little over the limit? Unfortunately most of us become victims due to stupidity of others. And, for one, I need no stupids in the same profession I am in. If they have to cheat to pass the test, they should not be in this profession. If they attempt to copy the test in a manner that they get busted, they deserve it and based on their poor ethic conduct, they donıt belong here. If they want to make proŜt by distributing the test so dumb ones can pass the test, they should be prosecuted and jailed.

If you copy a proper begin of styled text in Edit mode to the clipboard, you may paste it elsewhere and it remains styled - PASTE seems to add a matching by itself.

For the parts which require cculators, I would agree that any old RPN scientiŜc cculator would work, with two exceptions. The Ŝrst exception is that a many problems on the Civil PE exam det with nothing more than unit conversions. There were many problems that were very straight forward and a reasonable answer could be surmised by most engineers with some simple gebra, but the time consuming part was getting l the units compatible. The unit conversion features of the 48 series were a re time saver and even lowed me to double check my answers (and conversions) for accuracy. To do it by hand with tables of conversions would haven taken much longer. The shortŝ of ccs like the 32SII is that they have C->F and M->ft and such but not CFS->MGD or Lb-in -> Kip-ft which are native to the 48-49 or can be programmed. The 33s may have more conversions, but the literature doesnıt seem to hilight it. The second exception is losing a memory limited stack with multi-line display. I havenıt seen the 33S, but my 32SII and its 4 position stack and single line display are limiting to me after having grown accustomed to the new stack method. For me, the killer exam cc just needs the generic scientiŜc functions, a very large and comprehensive unit conversion library , multi-line dspy (3 or more lines) and at least a 20 or 30 positon stack. Though, I donıt know why I seem to care that much... I passed the exam and donıt have to fool with the new requirement. :) -J. Busby, P.E. === Subject: Re: NCEES bans certain cculators from test sites I took my P E exam in 1996 in Electric Engineering. If you answered many of the power related questions, as I did, the now banned cculators were great. The complex number capabilities of the 33S and 32SII just donıt measure up. Not lowing cculators with good complex number capabilities reduces the test from one of power engineering theory to one of complex number arithmetic.

One of most usefull advantages for HP42s is a easy put in and handling of numeric complex numbers and working on l functions like Œsqr, ln, log, exp, sin, cos,...ı without exception, and so handle complex numbers inside matrix... Easy to understand and very useful on electric cculation. This is very rare or impossible to Ŝnd good replacement to HP42s in different brands or model of _sml_ scientic pocket caculator...

For example: very common (and big size) TI83 can not handle -1 cos (2) properly (hp42s: acos(2) = 0 + i1.317, hp48 and hp49 give a same answer ) ie. complex number handling is incomplete inside TI83... ŒEasyı and cheap scientic cculator like CASIO fx-992s with big label Œcomplexı can _not_ handle easy question like: _______ / -1 What complex !!??? - this is form Œ1Aı to test if cculator can handle complex numbers or not!!! --- _______________ Is are very easy to cculate / r + jwl Z= / --------- / g + jwc for transmmissionline with few Ŝngertip on HP42s and give complex answer.

Iım counting display time. My program will do the factori, and the BCD conversion for display in under that time. for a cculator I think display time needs to b included in the arguement. Just to prove my point... Version 1.00 of FFAC used plain binary to cculate in. 5000! took under a second to cculate - but 3000! takes ~42 seconds, from the users point of view. Version 2.00 takes far longer to cculate, but the result of 3000! now takes about 8 seconds tot. What is more useful? I think version 2.00 is an improvement. Of course, Version 3.00 (Coming soon) is much much faster then version 2.00 :-) so, the heavy memory requirement will be lifted. > -- > Bhuvanesh === Subject: Re: NCEES bans certain cculators from test sites > Perhaps there is a case to be made for requiring the use > of sliderules for the exams.

What problem? It sounds to me like there rely isnıt one. Who has a cculator that can communicate more than 12-18 inches? When I took the test, everybody had their own table and they were spaced about 10 feet apart. Why would a communicating cculator be a problem? If I understand the cculator ban correctly, if you could plug a computer to a seri port in your computer when you got home that would be enough of a reason to ban it.

RS_hold_PASTE will by sure not clear the clipboard on the 49+. Its key function is ROMPTR A3 C whose content is just the same as the standard assignment of RS PASTE, i.e., beep if nothing is in the clipboard or paste otherwise. Clearing the clipboard is presently on RS_hold_COPY (confusing). Further, you describe the standard assignment of RS_hold_CUT incompletely. Namely, if no selection exist, it cuts the current line and appends it to the content of the clipboard. This differs in that from my answer to Bill that the key beeps if nothing is selected. Admittedly, I donıt need these functionities since I assigned the CUT-> command from Emacs to RS_hold_CUT. This command is clever. It cuts the line *from the cursor position on* and appends this to the clipboard if the CUT key is normly pressed. So you can append the linebreak in a second key press, then append the next line etc. In other words, you can quickly cut a few lines without making any selection. === Subject: Re: Upgrade 48GX to a 49+ > Hi Guys & Girls, > I have owned (and tweaked) a HP 48GX for 7 years now - still > going strong - an am wondering if the increase in speed & storage of > the 49+ is worth the money.

I have a problem with my HP 48 GX keyboard. l functions on the cculator work, however I think the keyboard became slightly warped somehow. Hence some of the keys in the middle of the keyboard need to be pressed hard in order for the keystroke to be registered. The strokes do register but keys have to be pressed rather hard in order for them to contact the board. Can anyone suggest how I could Ŝx this? I was thinking about opening up the cc and try to manuly ŝex the keyboard or the PC board, not sure what would be involved here. How would I open the cc? If I could Ŝx the cculator it would work just Ŝne because the screen and l the functions work Ŝne, just keys need to be pressed hard. I am not sure how this happened, maybe I left the clac in direct sunlight long ago in my car, canıt remember. === Subject: Re: NCEES bans certain cculators from test sites >> >> If you are competent, the problems on the exam are simple, straight >> forward and achievable, as previously said, with a $20 cculator.
