In this paper we suggest a three-language (3L) paradigm for building the program generator models. The basis of the paradigm is a relationship model of the specification, scripting and target languages. It is not necessary that all three languages would be the separate ones. We consider some internal relationship (roles) between the capabilities of a given language for specifying, scripting (gluing) and describing the domain functionality. We also assume that a target language is basic. We introduce domain architecture (functionality) with the generic components usually composed using the scripting and target languages. The specification language is for describing user's needs for the domain functionality to be extracted from the system. We present the framework for implementing the 3L paradigm and some results from the experimental systems developed for a validation of the approach.

We present the capabilities of the scripting language Open PROMOL and its processor. The intention of the language is to pre-program specifications for modifying programs written in a target language. We use its processor either as a tool for developing the stand-alone reusable components or as a “component-from-the-shelf” in generative tools for generating domain specific programs. The processor itself uses the module (lexical analyser and parser) produced by Lex & Yacc as a reusable component. We describe the generation, computation, control, parameterization and gluing capabilities of the language. We compare our approach with the similar approaches known in the literature.
