Hi Chris, I'm still using a patched Mail.Panel for reading mail with WinAos under XP. I guess it's somewhere in the net where you can download it. But it has a problem now for a couple of days. Reading is still possible, but sending doesn't work because of some new authentification scheme of my ISP :-( Cheers, Edgar

Oxford Oberon-2 Compiler and local procedures
by Martin Bishop 29 Nov '08

29 Nov '08

I translated some Pascal code for "deep binding" (aka closures) into Oberon. MODULE Closure; IMPORT Out; TYPE Function = PROCEDURE (); PROCEDURE A(I: INTEGER; P: Function); PROCEDURE B; BEGIN Out.Int(I,0); END B; BEGIN IF I > 1 THEN P ELSE A(2, B); END; END A; PROCEDURE C; BEGIN END C; BEGIN A(1, C); Out.Ln; END Closure. And here is the output from OO2C: martin@thinkpad:~/Code/Oberon$ oo2c --make Closure.Mod martin@thinkpad:~/Code/Oberon$ cd bin martin@thinkpad:~/Code/Oberon/bin$ ./Closure 1 which is correct. However, here is the output of the same program (renamed to Closure.m so the compiler accepts it) in the Oxford Oberon-2 Compiler (obc): martin@thinkpad:~$ obc -o Closure Closure.m "Closure.m", line 19: local procedure 'B' may not be used as a procedure value > A(2, B); > ^ Why does it not allow B to be used as a procedure value? After a little digging in the obc manual, I find a section that says: The scope of a procedure includes the bodies of all procedures defined at the same nesting level, without the need for “forward declarations”. In fact, such forward declarations are not permitted. I’m guessing this is what is screwing it up, but I don’t really know what that means. Does anyone have an idea as to why oo2c seems to compile the code just fine, and obc does not?

oo2c in ubuntu
by Martin Bishop 25 Nov '08

25 Nov '08

I typically use the oo2c compiler for developing Oberon, but recently (as of the release of Ubuntu 8.10, I believe) oo2c has been removed from the apt repository. Does anyone here know why/know the maintainer? oo2c was the only Oberon compiler in Ubuntu (or debian).

Weps <fmw(a)debian.org>, is apparently not active anymore. Therefore, I orphan this package now. If you want to be the new maintainer, please take it -- see http://www.debian.org/devel/wnpp/index.html#howto-o for detailed instructions how to adopt a package properly. see also: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=379224 The problem is that also the projects home page at sourceforge looks very orphaned (as noted by Stewart Greenhill, an active member of the project, see: http://sourceforge.net/mailarchive/forum.php?thread_name=49221C71.7070007%4… sers.sf.net&forum_name=ooc-compiler) [...] > oo2c was the only Oberon compiler in Ubuntu (or debian). > yes, that's a pity ... regards Bernhard

mail & uidl & etc.....
by Chris Glur 23 Nov '08

23 Nov '08

Because this mailing-list provides a bounce-confirm one expects other to do so too. I'm subscribed to the yahoo-simputer list, which is a disaster: filled with top-posting ONLY and much html. Perhaps posters work from inet-cafes. It's good to be subscribed from a gmail address, since one's relation to a particular ISP may be less permanent that to gmail. But the gmail web-interface is a curse. I general the move to clik-web is a curse ! Is it possible to email a pre-edited mail via gmail, without the multiple web-dialog ? I tried to mudge my "From:" field via Oberon.Text , which of course was stupid, because the ISP must give the return path. So I couldn't make it appear as coming from gmail. Over the years of installing differenet ETH-Oberon versions I got first only TextMail* working then Mail* , but never Mail.Panel . It now, [under Linux-ETH-Oberon] does: --- Trap 5.7 (Index out of range) sp = BFFFEBF0, bp = BFFFEE88, pc = 082FECEF Mail.Synchronize @ 11431 R = : Texts.Reader Ri = : Files.Rider .. uidl = "1203169508.M461068P44407V0800FF01I0299 2358_0.mx07.vox.co.za,S=62" ... user = "crglur(a)absamail.co.za" Oberon.Call @ 4705 Mod = 4034E820H : SysBasetypes.ModDesc ..etc. -------- uidl is a char[63] array, which is full as dumped here. I'm not yet prepared to d/l the whole Linux-ETH-Oberon source suite to debug this. But I'm curious to know what UIDL is ? My Ver 2001 N-O, where I *have* got Mail.Mod, traps differently than 'this' Linux-ETH-Oberon version. I'm guessing that as the mail headers became more bloated the mail-clients adapted. Does anybody use a pre-Win95 mail-client which is still ok ? == Chris Glur.

Enhanced OP2

Is it possible to have Enhanced OP2 running on Linux? That is, without running the Oberon system, or Bluebottle or any of that?

Re (2): [Oberon] simplifying Dialer

Joerg, Thanks for your reply and particularly for the reference to the OSI layers. I've never seen Linux chat and pppd explained so concisely. js> ... provide a kind of "chaining mechanism" (e.g. script) to facilitate things. Precisely what Dialer.Dial does. The last statement of the Dial script is normally "CALL PPPMain.StartInst". When dialing a telephone call this is omitted of course. js> Personally, I would not mix layer 1 and layer 2 functionality in one program ... Understood. The changes I imagine are merely to generalize parameter handling and would affect only the layer 1 capability. Specifically, (1) make the target number an optional parameter of the command rather than a constant in the Dial script and (2) make the device parameter optional. Considering that the syntax is quite specific---"Device0" or "Device1" or "Device2" ... ---the source code would not be excessive. This syntax might be acceptable. "Dialer.Dial" ScriptName [Parameter [Parameter]] "~" Parameter = Device | TargetNumber. Device = "Device0" | "Device1" ... . TargetNumber = Number | "P"Number | "T"Number. (For most modems, "P" and "T" invoke pulse and tone dialing.) Regards, ... Peter E.

simplifying Dialer
by peasthope＠shaw.ca 13 Nov '08

Oberon & Aos users, As I see, Dialer.Mod was designed to operate a modem for establishing a PPP connection. Currently I wonder about generalizing it to also dial a telephone number. Along with all other uses, the Desktop.Tool can be a telephone directory. This is my idea of generalizing the command syntax. If anyone can offer a suggestion or criticism ---thanks. Extant syntax is Dialer.Dial <config> <device> ~ For example "Dialer.Dial carnot Device0 ~". First I wonder about the benefit of the device being a parameter of the command rather than being in the Oberon.Text. For example, config.Init might be Init = { Device0 COM1 19200 } {* device, port and speed *}. Does anyone use more than one <device> with one <config>? Secondly, the number to dial could be a parameter. So the syntax could be Dialer.Dial <config> <device> <number> ~ or Dialer.Dial <config> <number> ~ . The generalized command would allow this to start a phone call. Dialer.Dial Nuvo 2501234567 ~ This command to start a PPP session. Dialer.Dial carnot 6042345678 ~ Of course the access numbers for the Nuvo card would be in the Nuvo Dial script in Oberon.Text. Thanks for any thoughts, ... Peter E.
