Abstract:

A typewriting/document editing system includes a signal encoding keyboard for serially entering alphanumeric and control key information characterizing a document being typed into one track of a plural track magnetic storage tape under central processor-stored program control. Each storage record includes an assembled processed line of text augmented by administrative character fields. When document editing is required, all changes (e. g. , deletions, insertions, substitutions, text relocations, and the like) are entered on a batched basis in an edit tape track. The stored text records are then marked with appropriate change descriptions ("Pass 1" operation), and the marked information and edit tape tracks compiled to form the desired revised text which is stored on a second tape ("Pass 2" operation). The revised text may thereafter be derived as desired by automated power typing.
