Abstract
An interactive data processing implemented method and apparatus for composing and editing a document in which a user is afforded great flexibility in defining the document geometry and in changing the data presentation characteristics associated with non-continguous portions of the document. According to the present invention, each of the distinct line formats in the document is assigned an abstract format name (i.e., a Named Format) and each line in the document is associated with a distinct format. A Names Format is associated with each fragment of the text in the document. Likewise, an abstract means, referred to as a Named Font, is associated with a wide range of specificable data presentation characteristics which operate over a range of the document defined by the user. The same Named Format and Names Font is used to simultaneously specify different data presentation characteristics for the output device of the system. By a single change in the specification for a Named Format or Named Font, all the underlying data throughout the text which is associated with a Named Format or Font is automatically changed to reflect the modified characteristic specification.
