Abstract

A method is described to preserve advanced datastream Revisable Form Text Document Content Architecture (RFTDCA) controls within the text of a simple, ASCII-based, word processing datastream so that a document can be brought in and returned to the advanced datastream without loss of data. Most word processors that interchange via the RFTDCA use a similar datastream internally to allow for the preservation of all controls in text, including those which the specific product may not recognize. This provides data integrity when these documents are interchanged. These word processors are all EBCDIC based, and have the capability of handling very large documents (> 100000 bytes). DisplayWrite 1 is the only word processor whose datastream is not structured like RFTDCA that will convert to and from RFTDCA.

Method to Preserve Unrecognized Controls in Text Portion of a DOCUMENT

A method is described to preserve advanced datastream Revisable Form Text Document Content Architecture (RFTDCA) controls within the text of a simple, ASCII-based, word processing datastream so that a document can be brought in and returned to the advanced datastream without loss of data. Most word processors that interchange via the RFTDCA use a similar datastream internally to allow for the preservation of all controls in text, including those which the specific product may not recognize. This provides data integrity when these documents are interchanged. These word processors are all EBCDIC based, and have the capability of handling very large documents (> 100000 bytes). DisplayWrite 1 is the only word processor whose datastream is not structured like RFTDCA that will convert to and from RFTDCA. However, it will only save a finite subset of the controls which appear in the text units of a RFTDCA document. This new method allows for the preservation of all multi-byte controls in these text units, in a small (document size limited to 32767 bytes), ASCII-based word processor. When a RFTDCA document is converted, all multi-byte controls which do not have an equivalent control in the word processor's internal format are encapsulated in the proper internal form for the word processor so that they will not be acted upon. If the control is too long, then it is broken into multiple pieces which are...
