Andrew as a multiparadigm environment for visual languages

Despite numerous innovations in visual languages, relatively little effort has been devoted to integrating visual languages with each other and with textual languages so each can be used for those purposes for which it is best suited. This paper advances a model for multiparadigm language environments which utilizes text in two roles, visual program organization and compiler input. The paper further shows that the Andrew User Interface System is a convenient framework for building language systems on this model. The approach is exemplified with a visual language for specification of string patterns.<<ETX>>
