Abstract

Page layout code in so-called "universal" document file formats (such as RTF) is customized to make the file format more universally compatible with word processor applications software across a spectrum of different manufacturers. The invention groups word processor applications into a "target list", and then customizes the page layout code so that document files distributed in the customized file format will be as universally receivable as possible within the word processor applications on the target list. A preferred embodiment of the invention customizes RTF code using "framing" techniques. For example, an empty paragraph of plain flowing text is inserted at the start of the document to enhance the compatibility with Microsoft Word. An empty frame is inserted at the start of the document to enhance compatibility with Corel WordPerfect. Other tuning is disclosed representing enhancements of compatibility with other commercial word processing packages.
