Re: Oberon Competition - Win a $US50 Amazon Gift Voucher

I'm not sure if I'm qualified to partecipate because I don't have Astrobe and neither a platform to test the code. MODULE Quiz; VAR a1*, a2*, init: ARRAY 1000 OF INTEGER; i: INTEGER; PROCEDURE Init*; BEGIN a1 := init; a2 := init END Init; BEGIN FOR i := 0 TO LEN(init) - 1 DO init[i] := i END END Qui...

Re: Nested procedures

Then we've lost the ability to make mutually recursive procedures if both of them are nested? :-(

Re: Updated Oberon Language Report (Revision 1.10.2013)

In my opinion BYTE and INTEGER shouldn't be assignment compatible, I don't see the need to assign an integer value to byte and viceversa because they are used for different stuff (except for the integer constant). Maybe Wirth did this to avoid a new type conversion function

Re: Nested procedures

I contacted Prof. Wirth and he stated that the report does not restrict variables to strictly-local-or-strictly-global access: In Oberon-7 "intermediate level" objects are permitted. However, in my new implementation they cannot be accessed, except from the level in which they are declared. Uhm, I'...

Declarations and Scope Rules [...] Variables and record fields marked with a minus in their declaration are read-only in importing modules. 4. Declarations and Scope Rules [...] Variables and record fields marke...

Re: Exported pointer variables

Uhm, I don't get your interpretation, then you consider public field identifers in a record as read only variables?

Re: Exported pointer variables

Hi, I've studied the Oberon-07/11 report in depth and my interpretation about the export mark is different. The report talks about the export mark in three places, in Declarations and scope rules (Ch. 4), Record Types (Ch. 6.3) and Modules (Ch. 11). In the first one, the export mark refers only to t...
