A syntax directed editor is an editor oriented towards a particular language. This paper describes a general table-driven syntax directed editor and an algorithm for automatically generating a syntax directed editor for a language from a description of that language. Aside from the convenience of a syntax directed editor, it is also a very efficient parser. No syntactic error recovery is required since the editor does not permit the user to make syntactic errors. Some of the implications of syntax directed editors for data structure manipulation and two dimensional languages are briefly discussed. (Author)
