The present paper introduces and discusses bidirectional contextualgrammars as a straightforward generalization of externally generatingcontextual grammars without choice. In essence, besides ordinaryderivation steps, the bidirectional contextual grammars can also makereduction steps, which shorten the rewritten strings. This paperdemonstrates that these grammars characterize the family of recursivelyenumerable languages. In fact, this characterization holds even interms of one-turn bidirectional contextual grammars, which can changederivations steps to reduction steps during the generation process nomore than once.
