Hi, 1- PC.Compile \s * of the following small test module gives no error message, even though module identifier is different. Builder.Compile gives the error "err 4 identifier does not match procedure name" while compiling. MODULE MyTest1; VAR x: REAL; BEGIN END MyTest. (* => should be "END MyTest1." *) 2- I played with W3dWorld stuff and wrote a module about 3d rotation of gears ( inspired from linux gl/gear.c). Initialy, I used ReplaceObject() method of W3dWorld module; I create gear object render it, then create a new gear with different rotation matrix and replace it with th previous one ....... This method seems fairly slow. So, instead of using ReplaceObject() method, I thought that it would be good if W3dWord.Object exports "vertices" and "nofVertices" fields, then object vertices can be changed by applying different matrices at runtime. Then, custom W3dWorld module with these changes, programs works continuously with high speed. Is there any other method that vertices of object can be changed with the program control. Could you add a method of changing the object vertices in W3*** modules in the next versions. I can send the program module as a contribution If it is going to be usefull.

OE03 ( final announcement )
by Philipp.Heuberger＠bluewin.ch 12 May '03

12 May '03

Hi Oberon freaks and friends, since the 2nd Oberon Evening at JLMC2000 a considerable amount of time has passed and the third Oberon Evening OE03 is coming up one month ahead. There has been continuous development of Oberon software during the last two years and I expect strong demand for applications running on comprehensive software systems as the ones that have their origin in the Oberon community. The "Third Oberon Evening" will take place on Monday, the 16 th of June 2003 in Winterthur . The exact place depends on the number of registrations received at the end of the month and will be notified two weeks before the event. The program looks roughly as follows. 18:00 Doors open Reception and Apéro Welcome 19:00 First part "Basics": Commercial Integration & Language Evolution Oberon for .NET AOS/Bluebottle-Oberon to Windows Jaos Zonnon 20:00 Second part "Apps": Wearable Devices Advanced Graphics "AntsInFields" "A timely walk for a Go" 21:00 Informal part "Plans": 22:00 Closing and farewell Thank you very much for your answers and proposals. I am looking forward to the event and I hope to get a reasonable group of people encouraged by the results of comprehensive software development. Please fill in the registration form below and send it in by eMail to philipp.heuberger(a)bluewin.ch well before the end of the month. For questions and comments, please give me a call to the number + 41 1 340 12 88. I am looking forward to your registrations, Philipp Heuberger --------------- r e g i s t r a t i o n f o r m ------------- First Name: Surname: Address: Phone: eMail: For the ones that give a presentation or demo, please send me a final description and how much time you think you need. There will be a printout of the final program including title and abstract. Title: Time: Abstract:

Chris & Edgar, cg> On the contrary, I think the attempt to integrate NetSystem, Dialer and ppp makes for complexity instead of 'modularlity'. OK. Please describe your best plan for organization of authentication parameters in Oberon. cg> 1. there is possibly a loginID and loginPassword to the ISP *before* entereing the ppp level. In general, yes this is possible. What is this server system you are dealing with? cg> 2. these 2 strings can contain any character sequence; therefore NO character can serve as an 'escape' char - at this stage. I do not understand whether we are discussing the handling of the authentication parameters in Oberon or the communication between the remote peer and Oberon. In PAP, the sender specifies the length of a word before sending it. The word can contain any octets and escape characters are never needed. cg> 3. once ppp level is entered 'escape' chars are applicable. RFC 1334 does not mention escape characters for transmission of the userid or password. cg> I'm waiting for a written acceptance (or denial) that the pre-ppp level ISP login and password can't be parsed by using ANY ascii-char (including""") as a token delimiter. The response to item 2 above applies here. cg> PS. How IS the UserID and password parsed in the login dialog with the ISP ? For PAP this is specified in RFC 1334. cg> Apparently by the 'line terminator' - <CR> and/or <LF> and perhaps a time pause ? This is reminiscent of the proprietary system named "First Class". It has only one authentication and not PAP. Just what system are you trying to access? Regards, P. http://carnot.pathology.ubc.ca/

Win32 Plugin Oberon , status report V

Hi everyone, although I was really working hard on the new WinPluginAos, it is not yet all done. I had some problems with deadlocks and with tracing bugs I have produced while not thinking deep enough before making changes to the garbage collection parts etc etc... [which wasn't only bad, I have really learned a lot!] Today it seems to be quite stable. I will give a more detailed overview when I have done some more steps in the next days. Some of you mentioned, that they need a version before easter (this year). It is too early to publish the current version now but for those who need an intermediate release: Please contact me (friedrich(a)gsf.de) Felix. -----BEGIN PGP SIGNATURE----- Version: PGP 8.0 (Build 294) Beta iQA/AwUBPb0WlkxdycIDx9VEEQLNcQCfV6Vvh6xm8wgomQ6Fy1fuGjXFq0IAn1qT 3wWElF69eNppXaSyxI2tKEhL =rmRz -----END PGP SIGNATURE------- Felix Friedrich Institut für Biomathematik und Biometrie GSF - Forschungszentrum für Umwelt und Gesundheit, GmbH Ingolstädter Landstraße 1, D-85764 Neuherberg Tel: ++49 89 3187 2436 email: friedrich(a)gsf.de --

Not at this point. You *MUST* know your correct user name and passphrase in order to authenticate via CHAP. If you don't, you're stuck. One remaining possibility is that your passphrase contains a special character, and you don't have it properly quoted. The one to be careful with is '\' -- it needs to be doubled (as \\) to pass through the parser. (And, of course, it *is* case-sensitive.) Another remaining possibility is that your peer doesn't actually want you to use CHAP, but rather to use PAP. Just change the name of the file from chap-secrets to pap-secrets to see. One last possibility is that your chat script is actually causing the problem. Most modern ISPs do *not* want you to log in via the chat script before starting PPP. Instead, you just dial the number, wait for CONNECT, and then launch straight into PPP -- no "login:", no password. Sorry I can't help more than that ... ---------------- end of expert opinion. ----------- I'm waiting for a written acceptance (or denial) that the pre-ppp level ISP login and password can't be parsed by using ANY ascii-char (including""") as a token delimiter. > es> ... using an escape syntax (%, \, 0x, ... whatever you > like).

This is the syntax in EBNF (to the > best of my small skill). Well, the first consideration must be reliability to work with any valid input. This consideration must over-ride symmetry and ease of use. Chris Glur -- PS. How IS the UserID and password parsed in the login dialog with the ISP ?

Doug, dd> Does anyone else share this dream? Probably many people in some sense. You must be familiar with the work of Douglas Engelbart. In case anyone is interested, a short biography is here. http://www.iath.virginia.edu/elab/hfl0035.html Abstract objectives persist through a long evolution of technologies! dd> Does anyone else share this dream strongly enough to kick around what it would take to form a company to sell such a device? So many ingredients are needed for commercial success and any of these ingredients are unappealing to people with a technical background. Luck and opportunity can also have decisive roles ... and success is ephemeral. dd> ... Oberon be the underlying OS for pen based displays ... Very appealing, yet a long persistent effort will be needed to get a practical result. Regards, Peter E. http://carnot.pathology.ubc.ca/

08 May '03

Hello Oberon'ers I am newly in this group and shortly would like to present me. My name ist Bruno Hürlimann an I am working with Oberon native (Version 22.6.02) and I am creating a graph for medical purpose. I am living in Zurich and I am interessted to find personally contact for example in form of the Oberon-User-Group, which existed earlier. My first two short Questions: 1) Where I can find the difference between Oberon native and Bluebottle? 2) Does Oberon native run on VMware? Greetings Bruno Hürlimann Verena Conzettstr. 15 8004 Zürich 01 291 56 45 079 762 46 01

Chris, Edgar, es> I guess Chris, Peter and me are the only people in the whole world using Oberon PPP so I think we can decide what to do :-) Good! es> 2. I (or a collaborator) adds a PPPMain.SetUser with an escape feature. Can we keep all the authentication in one command? Separation of NetSystem.SetUser and PPPMain.SetUser seems unOberonian. es> 1. Somebody who feels responsible for NetSystem.SetUser implements or allows to extend it More to my taste. es> ... using an escape syntax (%, \, 0x, ... whatever you like). I still think the syntax with ':' and '@' isn't bad. My preference is for symmetry between the arguments and to quote each argument rather than introduce escape characters which I will forget. This is the syntax in EBNF (to the best of my small skill). "NetSystem.SetUser1" { AuthenticationVector } "~". AuthenticationVector = ServiceType ServiceName user password. (A blank separated list of elements.) ServiceType = string. ServiceName = string. user = string. password = string.
