(a2/<platform>/work) versus (a2 > File Manager > WORK).

Hi, In the a2 File Manager, WORK is an alias for work. What is the benefit? Why not just work? Thanks, ... P.L. mobile: +1 778 951 5147 VoIP: +1 604 670 0140 https://en.wikibooks.org/wiki/User:PeterEasthope

Starting A2 from the SVN repository.

Hi, Just expanded the instructions for starting A2 from the SVN repository. https://en.wikibooks.org/wiki/Oberon/A2#Startup_from_the_Repository The instructions are from use in Debian Linux. I don't have access to MS Windows. Instructions for that are extrapolated. Corrections welcome. Editing welcome. Otherwise ask me to correct. Thx, ...

SYSTEM.PTR vs SYSTEM.ADDRESS
by Deadmarshal 01 Nov '22

01 Nov '22

Hi, What is the difference between SYSTEM.PTR and SYSTEM.ADDRESS? As far as I've read they both seem to be void pointers? How does one cast a void pointer in Oberon? for example in C we have: void *ptr; casting and dereferencing: *(int*)ptr; Do you also have a small example of how to use SYSTEM.Get() and SYSTEM.Put() functions? regards

SYSTEM.PTR is a pointer type, managed by the garbage collector, and SYSTEM.ADDRESS is an INTEGER. It is not managed by the garbage collector.

Realloc function and simulating continue and break in Oberon-07 loops
by Deadmarshal 24 Oct '22

24 Oct '22

Hi, I was wondering how one can break and continue loops in Oberon-07? In Oberon-2 there is a LOOP keyword which has EXIT to break the loop, but it is removed from Oberon-07, and the EXIT keyword can't be used in FOR or WHILE loops. I was also wondering if a realloc() function similar to C can be made in Oberon? Because it can be used to create dynamic arrays much like the CPP's std::vector. I am well aware that I could use a linked list for that purpose, but I'm curious about dynamic arrays. Regards

Yes I did promise that, but I recently couldn’t resist and decided to add some new features indeed, for example to allow importing modules in any order. However, all compilers of the repository - including said retro-compiler - are *always* automatically kept in sync with the mainline compiler ;-)

> Being a user, I would welcome closer collaboration. Adding a "retro" flag to the compiler would help Wojtek, just as a reminder: The retro-compiler under Extended Oberon is available at http://github.com/andreaspirklbauer/Oberon-retro-compiler This is your retro flag. It runs as is. Andreas

Naming; was, Re (3): Multiple RETURN in a procedure

Throughout the wikibook I've preserved original content and format as closely as possible. That includes names. In case a page is revised, earlier versions are available via history. From: peter(a)easthope.ca Date: Mon, 24 Oct 2022 06:24:04 -0700 > ... André's tutorials. Also in the wikibook is the ETH bibliography. https://en.wikibooks.org/wiki/Oberon/books The name "books" was on the ETH server. Therefore propagated here. Strictly, a misnomer. The majority of the documents are not books. The title of the page is "Oberon Bibliography". For consistency, I'd prefer this URL. https://en.wikibooks.org/wiki/Oberon/Bibliography The move can be a link allowing access vi both names. https://en.wikibooks.org/wiki/Oberon/Bibliography links to https://en.wikibooks.org/wiki/Oberon/books Or https://en.wikibooks.org/wiki/Oberon/books links to https://en.wikibooks.org/wiki/Oberon/Bibliography Will anyone view the change as disrespectful?

Inevitably, revision and testing reveals further possible improvements. Elusive bugs bite. (The devil is in the details.) Meanwhile other things need attention. A few days soon pass. Time flies when having fun. Regards, ... P.L. mobile: +1 778 951 5147 VoIP: +1 604 670 0140 https://en.wikibooks.org/wiki/User:PeterEasthope
