An introduction to the problems involved in conversion of computer dialogues from one computer language to another is presented. Conversion of individual dialogues by complete rewriting is straightforward, if tedious. To make a general conversion of a large group of heterogeneous dialogue material from one language to another at one step is more ambitious. Three possible approaches are seen. Original programs might be fed to some kind of interpretive processor. Or source programs might be read by a background program in some language, then converted to binaries and load modules for the new language. Finally, an entire editing program could be written to convert autonomously, but this task might in the end be too difficult or too constricting to further change. (RB)
