Re: Type compatibility rules summary.
Hi, I think you're referring to a question I posted but then deleted because I discovered it had already been answered earlier on this forum. The summary you link to mixes up types and type identifiers, and defines "same type" for two variables but then uses the term "same type" in a context that do...

Another clarification about local names
Hi again, The language definition states: The use of the procedure identifier in a call within its declaration implies recursive activation of the procedure. That would seem to rule this out as legitimate code: PROCEDURE P; PROCEDURE P; END P; (*local*) BEGIN P (*which P does this refer to?*) END P;...

Looking for clarification: local procedures cannot call local procedures, right?
Hi, The following code: PROCEDURE P; PROCEDURE Q; (*local*) ... END Q; PROCEDURE R; (*local*) BEGIN ... Q ... END R; END P; is disallowed by the definition of Oberon07, that is, local procedure R cannot call local procedure Q, since the identifier Q is not local to R and not global....

Re: Oberon Report Update 2016-05-01
Can an open array be the target of an assignment? From the Report: "The type of the expression must be the same as that of the designator" and "Strings can be assigned to any array of characters..." Here's a question: if an open array is assigned to an array of equal base type but shorter length, i...

Re: Nested procedures
Hmm. I think the report should say:Langugae report is now much clear
In addition to its formal parameters and locally declared objects, the objects declared globally are also visible in the procedure (except objects whose identifiers coincide with those of locally declared objects).
