Abstract

A method is described of operating only on the text portion of Revisable Form Text Document Content Architecture (RFTDCA) documents, while preserving the format information, footnotes, and non-text objects, while taking up a minimum of storage space in memory and on disk. All current word processors which convert to/from RFTDCA are EBCDIC-based programs, which are capable of handling extremely large files. All of their internal datastreams are in some fashion structured similar to RFTDCA. DisplayWrite 1 is the only word processor whose datastream is not structured similar to Revisable Form Text that attempts Revisable Form Text conversions. When it does this, however, all footnotes and non- text objects are lost, and the format information must be saved to a separate file on disk.

This text was extracted from a PDF file.
At least one non-text object (such as an image or picture) has been suppressed.
This is the abbreviated version, containing approximately 61% of the total text.

Method to Save Format and Non-Text Information in Word Processor

A method is described of operating only on the text portion of Revisable Form Text Document Content Architecture (RFTDCA) documents, while preserving the format information, footnotes, and non-text objects, while taking up a minimum of storage space in memory and on disk. All current word processors which convert to/from RFTDCA are EBCDIC-based programs, which are capable of handling extremely large files. All of their internal datastreams are in some fashion structured similar to RFTDCA. DisplayWrite 1 is the only word processor whose datastream is not structured similar to Revisable Form Text that attempts Revisable Form Text conversions. When it does this, however, all footnotes and non- text objects are lost, and the format information must be saved to a separate file on disk. This new method preserves all format information, footnote pages, and non-text objects, without using any additional space on disk. The RFTDCA document is shown in the figure. The input steps are as follows: Step 1: Pick up necessary information from format unit.

Step 2: Convert text units to internal form (text only).

Step 3: Ignore remainder of RFTDCA document. After the text portion of the document is brought in, the user may make any modifications which he desires. When the user wishes to save the document back out to revisable form, he is instructed to always save it back to the original. The following steps take plac...
