Hello Guenter & others,

In LinuxAos 7086, the Oberon subsystem encounters a problem at Oberon.Init.

Screenshot at http://easthope.ca/LinuxAosOberon7086.png .

The transcript from the terminal  follows.  Rev.6518 and 6661 work without this fault.

Regards,                               ... Peter E.

v6.0 of the Astrobe Oberon development system which allows you to develop embedded software for ARM Cortex-M3 and Cortex-M4 microcontrollers has now been released.

The latest (May 2016) revision of the Oberon language is fully supported and there is a new 'custom' linker feature that allows you to target microcontrollers other than NXP devices e.g. the STM32F100 used in the STM32 Discovery kit.

For more information see the announcement in the Astrobe Forum:

Dear Darek!

These modifiers are necessary for the another version A2-system, which is using cooperative multitasking.
https://en.wikipedia.org/wiki/Cooperative_multitasking
Look for example in sources folder Coop.*.Mod

Why do we need cooperative multitasking - I do not know Grin

Out of interest, for me - there were inline procedures is the speed in C macros, but safely.

Look SVN-repository comments for get more information. Also you can use FoxDocumentation to produce .html documentation, for example:
Compiler.Compile -d=*.html -i  oc/FoxDocumentationBackend.Mod ~

Best...

Hi,
 Browsing the source code of A2 system I came across these4 two modifiers:
   - UNCOOPERATIVE
   - UNCHECKED
what is their meaning?

Is there any newer version of the Active Oberon Language report? The "current" version
is from 2004. I know that Felix and his team has extended the compiler greatly (I use some of
these features) but I am not sure about the rest of the community.

Would be possible to publish an updated  version of the report?

Cheers,
 Darek

The latest revision of the Oberon Language report is 1.10.2013 / 4.3.2016. Changes since Revision 1.10.2013 / 18.3.2015 are:

Section 4 Declarations and scope rules

The following paragraph has been removed:

Quote
The scope rule has the following amendments:
1. If a type T is defined as POINTER TO T1 (see 6.4), the identifier T1 can be declared textually
following the declaration of T, but it must lie within the same scope.
2. Field identifiers of a record declaration (see 6.3) are valid in field designators only.

Section 8.2 Operators

set is qualified further:

Quote
The set {m .. n} denotes {m, m+1, ... , n-1, n}, and if m > n, the empty set.

Section 8.2.4 Relations

Quote
The relations <= and >= no longer apply to the type SET.

Section 9.8 For statements

Quote
The TO 'end' expression of the FOR statement is evaluated at every loop.

The Oberon report has been updated. <= and >= no longer apply to SET arguments AFAICS. (See section 8.2.4)
