In absence of potential ambiguity I omit the prefix. Some files have multiple levels of suffix. Eg. Sunset2023.01.03.jpg Sunset2023.02.13.jpg Sunset2023.02.17.jpg Prohibition of multiple periods suggested by HyperGaruda seems unnecessary. (?) Thanks, ... P.

File naming again.

Hello all, Martin Reiser published a syntax for file names. Quoted here. https://en.wikibooks.org/wiki/Oberon/Naming More discussion here. https://commons.wikimedia.org/wiki/Commons:Village_pump/Technical#Pattern_f… Near the bottom, HyperGaruda advised against inclusion of a period except to separate a name extension. Obviously inconsistent with the Reiser syntax. I miss the point. Is there harm from a period additional to the extension separator? Thx, ... P.L.

Ref. http://mail-index.netbsd.org/port-sparc/2023/03/15/msg002546.html "modern compilers are big." My thought was "Not all." "either try adding more swap, or ..." Or port an Oberon system to the bare machine? Haven't replied; for now at least. =8~/ Regards, ...

FOR loop variable

> Some implementations might not necessarily protect the "fixed number of > times", for example if they don't assign the limit expression to a > temporary variable at the start of the loop. YMMV. Literally. :) The mileage can even become infinite.. j := 10; FOR i := 1 TO j DO IF j MOD 10 = 0 THEN INC(j, 10) END (*mileage extension ;-)*) END This is not possible in Oberon-2, but Oberon-07 allows it.

FOR loop variable
by Ala'a Mohammad 16 Mar '23

16 Mar '23

Hi, I'm a beginner in Oberon-2 who had recently picked it up (learning it through practice). and really love the simplicity of the language. I need help to understand the need to declare FOR loop stepping's variable. (i.e x in FOR x := .....). I do not intend to change the language, but The question arises since this variable always (in my short exposure to Oberon-2) is scoped within the FOR loop body. And was trying to answer the question: Is it good design to have FOR implicitly declare its variable (It is not a big issue to declare VARiables), or Is it from the point of uniformity to have all variables declared with VAR? forgive any ignorance on my part Thanks for your time. Ala'a Regards,

Announcement: Astrobe for Cortex-M0
by Chris Burrows 07 Mar '23

07 Mar '23

We have now completed the development of Astrobe for Cortex-M0. We have rewritten the Astrobe Oberon-07 compiler's code generator so that it can now also be used to target ARM Cortex-M0 microcontrollers as well as Cortex-M3, M4 and M7: "The Arm® Cortex®-M0 is the smallest Arm® processor available, with a very small silicon area, low gate count, low power and minimal code footprint. Suitable for analog and mixed signal devices, it allows microcontroller suppliers to offer 32-bit performance at 16- and 8-bit price points. It is ideal for highly embedded applications." https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-cortex… The Personal Edition of Astrobe for Cortex-M0 is available free of charge. See the announcement on the Astrobe Forum for more information: https://www.astrobe.com/forum/viewtopic.php?f=3&t=744 Regards, Chris Burrows CFB Software https://www.astrobe.com

Tool Form in document
by Aubrey McIntosh 02 Mar '23

02 Mar '23

I am writing some documentation, and I wanted to put the Form into the document. I wanted it to work as it would in a Tool viewer, and act on the focus View. I read enough to get down into StdApi, and wrote a small app to edit Containers.GetOpts. I even made a local modification and introduced StdCmds.SetToolMode It is dawn, and I have no success. I can open the document in a Tool viewer, but I want the Form view to act as a tool as soon as the document is opened. -- Aubrey McIntosh, PhD

I backed my Ubuntu installation to 20.04, Focal, ran all the updates and installed wine. Both blackbox versions work. -- Aubrey McIntosh, PhD

Ubuntu 22.04 --> wine --> CPC
by Aubrey McIntosh 20 Feb '23

20 Feb '23

This weekend I upgraded my Ubuntu environment to 22.04, installed wine, and downloaded CPC from http://zinnamturm.eu/downloads.htm 1. I have put the CPC directory tree at /usr/lib/bin/CPC. Where is a better place to put it? 2. I have made ~/.config/autostart/CPC.desktop, attached. It has a /USE command line parameter, so that the distribution directory tree remains pristine. This seems pretty unremarkable, but if you spot anything strange, please mention it. 3. *Oops*. I checked that I could copy attributes by holding down MM in a selection, and dragging the mouse to text with the desired attributes and then releasing MM. This works as I remember from the past when working in the same window, but it does not work across CPC windows. By comparison, this does not work in the Denisov distribution as I have it configured. 4. *Oops*. Text cut and paste does not work. Surely this is a problem somewhere in the complexity of Ubuntu & wine. If anyone has seen this issue, I'd like to know how it turned out. Hint, I can copy text outside the CPC environment & paste it inside the environment. -- Aubrey McIntosh, PhD
