evaluation Message #1 Posted by Jack Stafford on 4 Sept 2002, 3:26 a.m. would some of you evaluate my RPN for windows and comment here or email? Euclid's RPN @ www.livingsoftware.net Thank you Jack

Re: evaluation Message #2 Posted by Christof (Davis, CA) on 4 Sept 2002, 3:36 a.m., in response to message #1 by Jack Stafford Any chance of a port to wince? (2.0, 2.0, or 2000 for HPC) for that matter, any existing ports? Nice calc so far, though. I tend to want a certian amount of direct code compatibility with the 41/42 series, but overall it's workign so far.

Re: evaluation Message #3 Posted by Jack Stafford on 4 Sept 2002, 3:50 a.m., in response to message #2 by Christof (Davis, CA) Thank you, keep me posted please Yes, I'm working on Pocket Euclid now Jack

Re: evaluation of Eucl;id - Congrats! Message #4 Posted by Vieira, Luiz C. (Brazil) on 7 Sept 2002, 12:02 a.m., in response to message #3 by Jack Stafford Hello, Jack. Great job! Which environment did you use to develop it? Delphi? Congratulations! I'm more to HW than to SW, but I am always amazed with any good SW expression. Success!

Re: evaluation of Eucl;id - Congrats! Message #5 Posted by Jack on 7 Sept 2002, 3:36 a.m., in response to message #4 by Vieira, Luiz C. (Brazil) Yes Delphi 6, how did you know? thank you for your good wishes Jack

Re: evaluation of Euclid - Congrats! Message #6 Posted by Vieira, Luiz C. (Brazil) on 7 Sept 2002, 10:42 a.m., in response to message #5 by Jack Hi; I'm not sure you'll agree with me, but I believe that development tools MUST be friendly, easy to use, so they will allow the developer to focus on the solution, not on how to use the tool itself. Delphi (as its Linux counterpart, Kylix) has proven to be friendly and powerful, not specifically easy to learn, but "easy to use". I would use Delphi to develop such applications, mostly because I'd have to learn it first, and I know it can be done... I like to use TK/GTK under Linux environment, but sometimes the functionality of the final product leads to a harder, bigger source code. I believe Delphi allows faster development in some specific cases. Anyway, simply knowing Delphi or any other tool will not lead to such final products as Euclid; the looks made me think of Delphi, but your own efforts are far beyond the scope of this brief analysis. That said, congrats again for the great job.

Re: evaluation of Euclid Message #7 Posted by Gordon Dyer on 6 Sept 2002, 3:35 p.m., in response to message #1 by Jack Stafford Euclid is a very nice calculator BUT I am an HP-11C user and would love to see a version which emulates the 11C including the key layout and key legends. Exclude the programming functions (for now), but include as many of the key functions as possible and keep the key legends the same as the HP-11C. I would like to see an option to turn on a display of the stack and storage register contents, this can be implemented in a seperate window. I will report any bugs if I find them. Anyway thanks for the good calculator.

Re: evaluation of Euclid Message #8 Posted by Jack Stafford on 6 Sept 2002, 11:21 p.m., in response to message #7 by Gordon Dyer I actually tried to steer away from emulating any particular HP calulator, although the HP-11C would be my choice too. I did try to keep the HP key legends where I could and stay within the three character convention (something that can easily typed). Euclid does have the stack display in a seperate window you mentioned you would like to see included. (use "STK" to display) Financial functions will be included soon. I'd be interested in what additional functions would be desirable. Thanks for your comments, Jack

Re: evaluation of Euclid Message #9 Posted by Christof (Davis, CA) on 7 Sept 2002, 2:21 a.m., in response to message #8 by Jack Stafford The only time I ever use windows is on the HP320LX and Jornada 720 handheld, though I did boot into a windows machine to try this. Programming is a fairly large want for me, and a good full run of statistics functions. Trig work is done - for me, at least- in places where I need a lot of portability. So that's not a huge issue in general. Onc eoyu get into solvers and such, it's almost time to use a regular CAS on the laptop. I think it would be really very sweet to have a selectable "style". say- a 15C type function set and a 12C type function set.

Re: evaluation of Euclid Message #10 Posted by Andrés C. Rodríguez (Argentina) on 7 Sept 2002, 7:12 p.m., in response to message #8 by Jack Stafford I have not seen your Euclid calculator, I assume from comments posted here that it is a nice and well done application. I hope you will be successful with the¨PocketPC version, because there are some RPN calculators for PocketPC, but I would like to use a RPN application which resembles the HP11C (well, a 41C or 42S would be better, but it may be too much to ask for!). None of the current PocketPC calculators I know about is close enough, BizCalc is acceptable, but is equivalent to a 12C and the keyboard layout is awkward in my opinion. By the way, there is a nice product for PalmOS, called MathU or MathUPro, from Creative Creek. very good, but only for Palms...

Pocket Euclid Message #11 Posted by Jack Stafford on 8 Sept 2002, 4:26 a.m., in response to message #10 by Andrés C. Rodríguez (Argentina) I don't see me doing an emulation of any particular HP-calculator with pocket Euclid either. Aside from the programming features which don't exist, Euclid is still way short of the HP-11 or any other real HP machine. My intent for Euclid was to be an RPN alternative to the "windows calculator". To provide a calculator with some teeth for the typical user in a form thats convienent to use alone or from within other applications. I knew that this is not a "typical Users" group but I also knew from hanging out here for the last several months that this was a great bunch of friendly, helpful people. I wanted to see how this "in the know" group would respond to my implementation of Euclids rather basic function set and I am grateful for eveyone's kind wishes and helpful remarks. I wish I could contribute more but I'm not much of an authority on math or machine. I'll be lurking here though, I do still have most of my HP's (35, 65, 67, 97, 12C, 15C, LX-100, and the 620LX). I was about to break ranks and buy a Compaq IPAQ but I waited long enough, it seems now it will also be an HP. If HP dosen't include RPN on the IPAQ then Pocket Euclid will! Cheers! Jack

Re: evaluation Message #12 Posted by thibaut.be on 18 Sept 2002, 9:19 a.m., in response to message #1 by Jack Stafford Hi, Congratulations, I really like your calculator. 3 tiny remarks on my side, that should not shadow the great appreciation I have for your work a) it would be great if the key legends were as similar as possible to the original HP calcs and if the layout were similar to the voyager series b) it would be great if you could set up 2 or 3 different layouts, one 11C/15C like, one 12C like and for the fans 16C like. These layouts could be toggled ob clicking on a button voyager logo like... c) I appreciated very much the register window. I might be wrong, but the T register(or U register on your calc, seems you added one) does not copy to Z (or to T) when the stack goes down one level : very useful for constant calculations. Anyway my congratulations ! it's easy making remarks on something you have not developed !
