Cooperating grammar systems

A new language generating mechanism is defined. It is derived from a generalization of the two-level substitution mechanism and involves several (incomplete) grammars which communicate with each other by introducing variables for which they have no productions themselves. When the grammars are context-free, this yields an alternative definition for the context-free programmed grammars. When the grammars are EOL (parallel) a class is found lying (strictly ?) between ETOL and CFP.
