[Oberon] Export of scalar/non scalar variables.

[Diego Sardina]

Hi there,

> But there is no definition for scalar type.

I asked Prof. Wirth more details about the term scalar type used in the Oberon Report. He replied with:

>> The word "scalar" means "on a scale". It is not a specific technical term.
>> As for Oberon, it is actually synonymous with basic, or with "not
>> structured".

>> Both unstructured and structured variables are supposd to be exported as "read-only".

He also sent me a more recent report with the correct sentence, it is now:

>> Variables are always exported in read-only mode.

This is the reason structured variables are exported in the new Oberon book.
