The destination path I gave for the decoded file in EasyOS was nonexistent. In Devuan my working directory for A2 is /home/root/A/. In EasyOS it's /root/A/. Stared at /home/root/A/ repeatedly; didn't register until today; brain was off-line. Compiling the current sources was a needed exercise. Thanks. Also need to add notes about EasyOS and compiling to the wikibook. Thx! ... P.L. -- mobile: +1 778 951 5147 VoIP: +1 778 508 0020 projects: en.wikibooks.org/wiki/User:PeterEasthope

A new programming language "GWD" and its compiler/interpreter.
by Srinivas Nayak 09 Jan '26

09 Jan '26

Dear All, Wishing you all a Happy New year 2026. Here, I would like to share my joy with you. Towards end of 2025, I was working on my little programming language "GWD" and its compiler. It was inspired by our master Niklaus Wirth. It was my wish to create a small language like Oberon, and learn compiler design from Wirth's Oberon compiler. Mainly because it used recursive descent parsing, and syntax driven translation for code generation. I was inspired by his idea of extending Record to support Object Orientation as well. Designing a simple VM was also inspired by him. Kindly have a look at it here: https://github.com/snayaksnayak/gwd I will wait to hear your kind feedbacks. Sincerely, Srinivas Nayak +91 9090406225

ETH Oberon version numbers.

Greetings for the New Year, I happened to find https://semvir.org and linked it in the footnote for the first entry in the glossary. https://en.wikibooks.org/wiki/Oberon/Glossary What I've written is speculative. Another possibility: the Lilith workstation was major 1, Ceres V1 was 2.1, Ceres V2 was 2.2 and PC Native Oberon was 2.3. Hence ETHO 2.3.6 and 2.3.7. People active in the early years are still alive. Can someone provide a more definite explanation? Thanks! ... P.L. -- mobile: +1 778 951 5147 VoIP: +1 778 508 0020 projects: en.wikibooks.org/wiki/User:PeterEasthope

Thanks. Will review. My tests are small. My sketchy thinking: Oberon.Files.Write puts one character at a time into a buffer in memory. After Base64 decoding is complete, Files.Register copies the buffer to persistent storage. (What if the Linux code invoked by Files.Write differs between Devuan and Easy?) Will try again after compiling. Thanks! ... P.L. -- mobile: +1 778 951 5147 VoIP: +1 778 508 0020 projects: en.wikibooks.org/wiki/User:PeterEasthope

Compilation of A2.
by peter＠easthope.ca 28 Dec '25

Hi, greetings for the pending New Year. I'm trying A2 on EasyOS. https://easyos.org/ Where most Linuxes use the commands in util-linux, EasyOS uses the similar commands in BusyBox. To make one start script work in EasyOS and in other Linuxes, UUID is referenced without /dev/disk and other complications. Simplification! =8~) Thus far, the only serious snag on EasyOS is Base64.Decode always trapping. Narrowed to a failure of Files.Write at the first output character. Recompiled Oberon.Files.Mod and saw the new base types noted. With the new types introduced years ago; I wonder why compilation catches the changes only now. Executables don't keep up with sources? Recompilation of Oberon.Files.Mod doesn't solve the Base64.Decode trap. * When does a complete recompilation of the A2 system happen? * Ideas about the trap at Files.Write()? * With A2 on Debian and on Devuan, Base64.Decode works flawlessly. Ideas about the trap on EasyOS. Thanks! ... P. -- mobile: +1 778 951 5147 VoIP: +1 778 508 0020 projects: en.wikibooks.org/wiki/User:PeterEasthope

I run a project to create a native Oberon compiler for Mac (ARM64, Apple Silicon): http://github.com/kekcleader/moc You could support or maybe just with ideas/comments etc.

You can try a java based implementation of Oberon 07, known as OberonC ( https://github.com/lboasso/oberonc) It is a little crippled when compared to the original Oberon, but you can still play with it and get a little taste of Oberon. Another implementation I use is Vishap Oberon ( https://github.com/vishapoberon/compiler) Maybe you can build it from source. This is an Oberon 2 compiler. I hope this helps.
