TIA... > Before I leave the inet connection for the location where CD-based A2 can tackle stuborn wireless modems, let me tell that: Wirth [& apparetly it's a Swiss attribute] uses a minimal number of unambigious concepts. That's how the best science works. In the context of ETHO what is a "PAGE" ?! ETHO provides: * files - which contain the text and possibly the font & colur info of the contained text; * which you can render on the screen, * in frames * of either 'text' * or 'Document' [which are active objects] type. On my leo screen now, I've got a C.Tool from my old N-O system which has a M.P [M.P is a concept you MUST know] " CRGtrace.Font2MrkdVwr Courier8.Scn.Fnt ~ " reading my chosen 'name' reminds me that this M.P does: make the <font specified as the arg> apply the the 'marked' viewer. OK, that doesn't prove that it applies to the WHOLE text. So I'll just mark 'this viewer that I'm writing in now' and klux the M.P. And yes!! The whole viewer's font changes; and I'll now klux back via: CRGtrace.Font2MrkdVwr Oberon10.Scn.Fnt ~ The point of the above, is that a decade ago, when I started ETHO, I made a few utilities by modifying the examples in *apter*.Text This served as a teaching exercise, and gave utilities that I've used since then. You should do the same. And important to your query IIRC the example in *apter*.Text that I used/modified, explained exactly that/why/ how to change the font of the whole frame/viewer including the part that you can't see 'now'. Thanks, == Chris Glur. PS. IMO 'computer-suitable'/step-by-step instructions are not good for explanations to humans. The reader/learner needs to be helped to build an appropriate mental model of the 'system' , to make his/her own 'algorithms', of how to 'get from A to B'.

Hello List.... I want to enlarge the font size of a multi-page document (some documentation). I can do it one visible screen at a time, but is there a way to "select" the entire document and resize the font? TIA... -- Duke

The week-end, inet-access-PC here, doesn't display CD-based A2, after the initial DOS-based <loading Oberon> mesg. I'm guessing the video is incompatible. The during-week-PC 20 Km away, IIRC showed [under Inspect -> USB] the USBmouse & the fake USB CDROM, as "Port1: Port2:". I don't know how to 'associate' "Port1: Port2:" with a <dev> ?! Also under linux I don't know the corrersponding /dev/* for "USB device 00:07.2-2, assigned address 5" eg. when I log the following test results:--- -> move USB connector == Code: 8b 40 24 8b 40 04 85 c0 74 14 ff 40 10 8b 06 8b 40 10 8b 40 <6>usb.c: USB disconnect on device 00:07.2-1 address 3 <--- FROM hub.c: new USB device 00:07.2-1, assigned address 4 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 4 usb.c: USB disconnect on device 00:07.2-1 address 4 hub.c: new USB device 00:07.2-2, assigned address 5 <-- TO WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 5 ------------------------------------ AND CD-A2 won't mount any IDE, and after I install CD-A2 to a partition, my diskette-booter from years of N-O usage, shows blank-screen, when I try to boot the assumed installed A2, and blank-screen for the previously tested ETHN-O partition too. Apparently the video setting is incompatible with the 'installation' but not with the CD version. I move my main IDE between the 2 PCs. Also very strange is that, the PC that runs ETHlinuxOberon with a PS2 mouse, needs a USB mouse for A2. Of course you'd have to `mount <dev>` before you could <eject dev>, but CD-A2 won't mount ANYTHING ?! Thanks, == Chris Glur.

How is ETHO with USB? -> 2252+ is a beast!

Sven wrote: > This 2252+ seems to be a beast ;-) I thought it was designed by <qualicom> and just made in China. Probably the original ones were, and the later models are attempted reverse engineering. I read the: guide_to_configuration_huawei_usb_fwt_macosdriverv2.9.9.doc ==" Confidentiality level FWT For internal use only Product version Total 14 pages Guide to Configuration of Huawei USB FWT Mac OS Driver Prepared by HopeCao (ID: 37496) Date 2008-3-18 ..." This document doesn't identify which model device it refers to ?! BTW it's quiet tricky to convert M$:Word.doc to ETH:Aos format on a linux machine. I took this beast to the laptop-shop to buy a laptop IDE with WinXP installed on the one partition [only for the wireless modem uses]; but the '2252+ failed to install, after as we've repeatedly seen, IDing itself as a CDROM. So apparently this particular device is defective. What a can of worms !! NO wonder everybody just buys a preinstalled box from Wallmart -- and follows the rest of the herd, thinking they can live off of credit from their house mortgage. Thanks, == Chris Glur. PS. the laptop-shop showed me his <VM*> [I can't remember exact names since using N-O for 15 years, where I only need to recognise and not remember] which was running ubuntu-linux under WinXP. He tells me that this <VM*> is available to emulate Win?? under linux. So would I then have a WinXP in some partition, and be able to run the wireless-modem under linux -> emulated WinXP, and be able to switch to ETHOlinux ?

And yes, initial compiling should best be done without the gadgets system. Just use ET.Open <your Source file> . Edit and compile some of the well designed examples in the tutor. Q. where are the examples in the tutor? A. search for "xample" on files *.Text -> System.Directory *.Text == ..... --> either use Find.Tool or Find.Panel or just open each particular *.Text and use the Frame's "Search" from its top menu to find "xample". ==> Chapter5.Text = The Programmer's Guide has: MODULE Example1; MODULE Example2; .. MODULE Example7; .. These are all good/well-designed examples. You can't avoid reading most of the Chapter*.Text files !! Use successive refinement: start with a simple working example, and extend it repeatedly, to get to an interesting [for you] destination.

Mount command
by Stauber Sven Philipp 26 Aug '10

26 Aug '10

> But no one will advise he how to mount IDE from my CD-A2 installation ? Sorry, overlooked this... FSTools.Mount Prefix Alias dev#part ~ is the A2 command to mount your IDE. Example: FSTools.Mount MyIDE AosFS IDE0#1 ~ Note that at some point in time, the AosFS data structures were modified to support longer filenames. If the mount command above complains about incompatibility of file systems, try: FSTools.Mount MyIDE OldAosFS IDE0#1 ~ ("OldAosFS" instead of "AosFS"!) You can also start A2 commands within the "grey box" (Oberon application) using the command Aos.Call commandName parameters, e.g. Aos.Call FSTools.Mount MyIDE AosFS IDE0#1 ~ (MM on Aos.Call) If you prefer mouse, you can start Menu -> Files -> Partitions (in A2), select the partition to be mounted and press on mount (the tool automatically determines the file system). >Looking at *.c code under linux / mc / mcedit with it's syntax colouring, really makes the code structure much clearer. We would want to often reverse engineer existing C-code; and we should slowly evolve utility/s to help us. The Programmer's Editing Tool (PET) of A2 supports generic syntax highlighting.

Duke, > That's the _first_ thing I tried! To my surprise, nothing showed up. I > then tried *.LOG; *.log; etc - no joy! Otherwise, I wouldn't have > asked the question. :) It's something simple but not obvious. You are using [Open ^] and not [Open]? Did you get Gadgets from the diskette set or from the ftp server? Was the Gadgets release consistent with the system release? Ie., everything was either beta or alpha and not a mixture? There should be a way to open the Gadgets desktop in the User track while leaving the System track visible. That would allow you to follow the System.Log. For now I'm out of ideas. What about using the compiler from the TUI at least until the GUI is more cooperative? And of course, Gadgets can always be troubleshot using traditional methods of inserting landmarks in the source to be monitored in the System.Log. Regards, ...

A few "Oberon.Desk" questions

Hello List... Hope everybody is done coughing British Columbia smoke - if any of you are "in the way". ;) Q1: At the moment, my NO boots with System.Log and System.Tool. I manually "activate" Oberon.Desk, then Builder.Tool to practice hacking Oberon code. I need System.Log while in Oberon.Desk. How do I get that to happen? Q2: Oberon.Desk opens with Gadgets.Panel and Document.Panel. Where do I tell Oberon.Desk to automagically open other panels? As usual, TIA... -- Duke

You manually load-and-display the contents of the files .... > I need System.Log while in Oberon.Desk. How do I get that > to happen? You want to have access to see System.Log , to know what's happening. Presently my System.Log opens as a DocumentFrame by default; IIRC that's determined by the <Init> field in Oberon.Text . On my old system it used to open as a TextFrame. During this 3-day session I mistakenly 'closed' my System.Log Frame and a lot of stuff which had been logged from inet fetches, and which I had not yet saved to file was no longer visible! Fortunately ET.Tool leads to a cmnd which [I don't WANT to remember] which displays a System.Log TextFrame with the contents of the previously closed - and lost to view System.Log Frame. NB, the Frame and the corresponding file differ in 'content' if you have changed to frame and not yet Stored it. Conventionally, one would not save System.Log but I do: usinging it for 'notes which are very HOT and current', especially for V4. When I have'nt used V4 for some time and have forgotten what project/s is current; I just klux the already visible 'System.Log'. IMO all sytems should start with an entry menu or a single token that you can remember: to be the top/entry to the 'task tree'. >Q2: Oberon.Desk opens with Gadgets.Panel and Document.Panel. OK !! I had to think. Do you really prefer Oberon.Desk to the 2-track system? I'd be interested to know if any 'old-users' prefer developing via the Desktop. And I want to investigate A2's IDE, after someone tells me how to mount/save my work !? AFAIK Oberon.Desk is merely 'a' DocetFrame which takes both tracks by default, and has a number of embedded gadgets to allow you to open files/gadgets ...etc. There's little advantage in trying to ape M$-Win. > Where do I tell Oberon.Desk to automagically open other panels? Panels are Gadgets/ActiveObjects/DocumentFrames. To forcefully get the message of this reality, you should 'open a DocumentFrame' on copyPaste an image into it, by exaxctly the same kluxing that copies a text-stretch to a frame: MR the source-image [causes it to go transparent and show that it's selected - IIRC] and ML/MM causes it to be pasted to the destination -- caret. When you MM/MR on a <fileName> in a textFrame/DocetFrame the corresponding <fileName> is displayed as a textFrame/DocetFrame respectively. So, kluxing the "other panels' name" in any DocetFrame "automagically opens that <other panel>"; OR more directly in concept but less directly in action eg: Desktops.OpenDoc FontEditor.Panel Ie. "Desktops.OpenDoc FontEditor.Panel" follows the formal syntax of" : M.P <args> <Module>.<Proc> == "Desktops.OpenDoc" <argumentList> == "FontEditor.Panel" But with kluxing, you just look at the name and THINK 'I want to see the contents of that file displayed'. Thanks, == Chris Glur.
