The present paper discusses the uniform generation of languages by scattered context grammars. More specifically, it demonstrates that every recursively enumerable language can be generated by a scattered context grammar, G, so that every sentential form in a generation of a sentence has the form y_1\ldots y_m i, where u is a terminal word and each y_i is a permutation either of two equally long words, z_1 \in \{A, B, C\}^* and z_2 \in \{ A, B, D\}^*, where A, B, C, and D are G's nonterminals. Then, it presents an analogical result so that u precedes y_1\ldots y_m. @ARTICLE{ author = {Alexander Meduna}, title = {Uniform Generation of Languages by Scattered Context Grammars}, pages = {231--235}, booktitle = {Fundamenta informaticae}, journal = {Fundamenta Informaticae}, volume = {2001}, number = {45}, year = {2001}, location = {Warszawa, PL}, ISSN = {0169-2968}, language = {english}, url = {http://www.fit.vutbr.cz/research/view_pub.php?id=6184} }
