The intent of this paper is to illustrate the following general ideas: -- Use of the context free grammar of a programming language as an integrated part of its programming system. -- Reconsideration of the border line between language and system. -- Systematic modularization of programs for the various translation phases. The specific ideas presented in this paper are language independent methods for handling: -- Modularization of programs. -- Separate translation in the form of context sensitive parsing (type checking) of modules. -- Protection of part of a module, e.g. protection of the representation of an abstract data type. The mechanism for modularization is unusual as it is based on the context-free syntax of the language. A module may be a sentential form generated by any nonterminal of the grammar.
