Modules.Mod.txt for Project Oberon (New Edition 2013)

It looks like Modules.Mod.txt has arrived at http://www.inf.ethz.ch/personal/wirth/ProjectOberon/ (But the compiler modules are misnamed: they have lost the X (i.e. ORSX.Mod.txt => ORS.Mod.txt) in the links on that page but seem to be still available on the server under their 'X' forms.) Warm regards, ~Simon

Export of scalar/non scalar variables.

Hi! In Oberon language report 2013 there is rule: > Variables cannot be exported, with the exception of those of scalar types in read-only mode. But there is no definition for scalar type. Also in Project Oberon 2013 (which uses Oberon-07/13) module ORS exports array variable: MODULE ORS; TYPE Ident* = ARRAY IdLen OF CHAR; VAR id*: Ident; END ORS. Array of char - scalar? Thanks, Alexey.

For anyone new to the system, OberonText.html is invaluable. Google found a link to it but I haven't. Each of http://www.ethoberon.ethz.ch/betainst.html and http://www.ethoberon.ethz.ch/betadocu.html could have a link. Group can be multiple. Configuration = Group . should be Configuration = { Group } . ? Regards, ...

A few comments about the Web page, primarily for ETH staff. The title of the page cited in the Subject is "Introduction to ETH Oberon / PC Native alpha and beta release". In referring to both alpha and beta, the title is perfectly appropriate. I've used the alpha for years and found the documentation almost indispensable. In the page we read this. "Latest PC Native Beta Release (08.12.00) [next beta early 2003] - Download - Documentation - FAQ - Change log Latest PC Native Alpha Version (updated often) - Change log - Download" Having the Documentation link under the Alpha heading, just as under the Beta heading, would be legitimate and helpful. The order of the links in Alpha and Beta cases is inconsistent. Should be "Download ... Change log" or "Change log ... Download" in both cases. In the Alpha case, "updated often" is false and should be deleted. Best Regards, ...
