Adaptable Systems Linguistic and Processing Properties. Part Two

As continuation of the research results [Tod-05.3] in this paper metalinguistic tools used in the process of introduction of new constructions (data, operations, instructions and controls) are developed. It was done the overview of extensible languages according used extension mechanisms, presented by different types of extenders. Extensions in languages and systems are defined according different phases of translation such as lexical analysis, syntactical control, semantic analysis, translation into intermediate language, and link phase. It was presented a lot of extensible languages and systems and examples of usage of different types of extenders. The generalization schemes of evaluation of adaptable languages and systems are discussed. Development of the research in Adaptable Programming Basis [Tod-05.1,2,3] is presented. These results analogically with [Tod-05.2,3] are obtained by the team, composed from the researchers D. Todoroi [Tod-05.4], Z. Todoroi [ZTod-05], and D. Micusa [Mic-03]. Present results are included in the book [Tod-06]
