Each line within a nlxx-file is regarded as a natural language instruction.
The single exception of the first statement is that the textual description of a Feature or Behaviour in the header of nlxx-files are ignored for text execution.
A natural language instruction may be represented by any sequence of characters.
A single instruction line may contain any number of data values or references on data values or data objects.
All values and references must be indicated by corresponding symbols.
All characters within two quotation marks are regarded as a data value (e.g. This is a "A data value") or as a reference on a data value (e.g. This is a "StandardCustomer::Name").
All characters within the < and > symbol are regarded as a declaration of a Dynamic Data Object (e.g. An < order > is created).
All characters within two apostrophies are regarded as a reference on a Dynamic Data Object (e.g. The 'order' contains the order number "123").
