Abstract: A document preparation program for use in connection with a word processing facility includes a succinct identification and listing of designated parts of a memorandum or document, each unique part having access to an associated file which contains the basic text and formatting controls for that particular part. The user of the program may readily assemble a document from the parts inventory displayed on a master screen by mere cursor reference or by keying the name of designated parts and have the newly created document displayed, or printed in most cases without reference to additional screens.
