I thought it might be a good idea to start making a FAQ (Frequently asked questions) list for the HP28C, HP28S, and HP48SX. We can post this list every month or so. Here are my first few lines: - HP28C: to find out the version execute HEX then #A SYSEVAL. It will be 1BB or 1CC. - the version of your HP28S is 2CC - HP48SX: to find out the version type ON-D, Backspace, EVAL. type ON-C to get back to the real world. - type ON-x as follows: press ON, press x, release ON, release x. - HP48: flag 19 determines whether 2D makes a vector or a complex number - HP48: other flags (34, 33, 62) - HP48: Vectored ENTER means that \GaENTER and \GbENTER are executed as follows: (long story) - split a matrix in rows by using \Gs- - build a matrix from rows by using \Gs+ - Your calculator is very accurate, but not infinite. Don't expect 'SQ(\v/2)' to be exactly 2. - Press \pi (or \Gp?) \->NUM to get pi. Same for e, i, MINR, MAXR. - Use \->ASC to post binary objects. - Mind the values of your symbolic, constant, function evaluation flags. - (explanation of infinite result, and like flags) - (table of \ codes, following the 48 manual) - (list of archive sites) Everything is open for discussion. Any comments? Bob, Alonzo, Jake, Wlodek, Eric, anybody else? -- | | "Never imagine yourself not to be otherwise than what | | Jurjen N.E.

I think it's a great idea to have a frequently-asked-question list. More and more folks seem to be getting onto this area, so a regular posting of the list is prudent. Speaking of the ROM version of the HP48, (and I think this was posted earlier, but) the HP48 Programmers Reference Manual also men- tions that you can execute #30794h SYSEVAL to see the version number in a string "HPHP48-n" where n is A, B, etc. Jake Schwartz

The list looks good. Possible additions would be:
1. Telephone numbers for EduCalc and Elec Tek
2. Names, addresses, and meeting times and places of user groups (perhaps a
separate posting of its own?)

I think that a FAQ list is an excellent idea. I have several questions I have hesitated to ask because I know they will waste people's time. Some of my questions are covered in the proposed FAQ list, but here are some more: 1) Is there a list of ftp libraries? I have found some by perusing a few dozen previous messages, but a complete list would be helpful. 2) Is there such a thing as a delta-manual for 28 to 48 transition (I read the recent message about Dr. Wickes' book on transitions, and I plan to get that, but a short snappy book on the differences between the 28 and the 48 would be helpful on its own). 3) Most of the programs I have seen listed here and on the one ftp library I have perused have been, well, more programmer-oriented than mathematical-end-user oriented. I have about 50 or so programs which are more mathematical, so they may be of less interest to the people reading this forum. I know of the existence of some first-rate special functions software written for the 28 by Dr. Henry Thacher. Is there a depot specifically for mathematical applications software? I would be happy to post mine there and to see if Dr. Thacher would post his there. That is, as soon as I get a cable for my 48 and the 28->48 receiving program going. 4) Several programs recieve special mention (e.g. Dr. Wickes' ->ASC (?)) but I have no idea where to find them. A list of the libraries with some idea of the contents, not just their location, might help with questions like these. -- ======== Robert Corless, Applied Mathematics, University of Western Ontario ======== London, Ontario, Canada N6A 5B9 e-mail : RCORLESS@uwovax.uwo.ca

Here at wuarchive.wustl.edu there is a specific subdirectory that contains math software. So you are welcome to upload programs in this category too. Please include a short description in every file, so that I easily can decide in which directory to place the programs. -- ******************************************************* Povl H.

Me too.
If there is such a list could it be accompanied by a 2d posting (suitable
for including into comp.archives, hint hint) with ftp site information
and other archive info? I'd like to put that stuff into comp.archives
regularly, & it's easiest if it's a separate post.
