.CHAPTER INTRODUCTION .skip RUNOFF (RNO) is a PDP-11 program to facilitate the preparation of typed or printed manuscripts, such as memos, manuals, etc. The user prepares his material on any regular PDP-11 terminal, and writes it onto a file using an appropriate editor. The user includes not only textual material, but also case and formatting information. RUNOFF then takes the file and reproduces it onto the line printer, terminal or other file to produce a final copy or final file image. It performs the formatting and case shifting as directed, and will also perform line justification, page numbering and titling, etc., as desired. .skip The principal benefit of such a program is that files prepared for use with it may be easily edited and corrected. Small or large amounts of material may be added or deleted, and unchanged material need not be retyped. After a set of changes, the program may be operated to produce a new copy which is properly paged and formatted. Documentation may thus be updated as necessary without requiring extensive retyping.
