2947	 SITAR An Interactive Text Processing System for Small Computers	 SITAR a low-cost in teractive text handling and text analysis system for nontechnical users is in many ways comparable to in teractive bibliographical search and retrieval systems but has several additional features. It is implemented on a PDP time-sharing computer invoked by a CRT with microprogrammed editing functions. It uses a simple command language designating a function a file and a search template consisting of the textual string desired and strings delimiting the context in which the hit is to be delivered. Extensive experience with SITAR shows that the combined powers of simple commands string orientation circular file structure a CRT with local memory and conversational computing produce a system much more powerful than the sum of its parts. information retrieval text editing minicomputers CRTs time sharing bibliographic search and retrieval literary analysis linguistic analysis command languages
