The ability of the computer to generate output not included in the input may be used for linguistic as well as for computational input. The ability to accept linguistic data and process it according to a certain program seems to be a promising field for investigation. Progress in this field may strengthen the assumption that the computer can be considered as a model for at least that part of the human brain that contains "knowledge of language(s)." If, for example, a program can be written for all inflected forms (in an inflectional language), when the input is an entry-word, the program will be stronger than any published conjugation chart. In programs for generating or transforming sentences, well-built sentences that have never before been heard or written may be generated without any restriction. Students may explore the field for themselves in an inductive way with the computer acting as a reliable "informer." As an illustration of the preceding, two examples are given for the generating ability of the computer: inflection Hebrew verbs and the extra-position transformation of Hebrew sentences. An explanation is given for each example as well as charts printed by the computer. Programs such as these might be useful for students of foreign languages. It is suggested that they might also show how far a computer can help to formulate grammar. (AMH)
