By repeatedly referring to the page information (FIG. 5) existing at the acquired address and acquiring the frame number 5a of the frame existing in the background page, display processing steps S20h to S20h are performed for all the frames existing in the background page. Perform S20m (step S20g). The display processing steps S20h to S20m further include a word processing data display processing step S20.
20h to step S20j and graphic data display processing steps S20k to S20m. The display processing is the same as the above-described background page word processing data display processing steps S20a to S20c.

Finally, the procedure for acquiring the edited data in the present embodiment will be described with reference to the flowchart in FIG. The procedure for acquiring the edited data is as follows: when the edited data is received, the frame type (background page or frame) of the frame in which the edited data exists, the frame number of the frame in which the edited data exists, and the application number of the edited data Returns edit data, and if no edit data exists, returns that no edit data exists.

First, using the frame type / frame number / application number received as input, the data I of FIG.
D is generated (step S21a). Next, the editing data management table (FIG. 8) is searched to determine whether there is an entry whose data ID generated in step S21a matches the data ID 8a in the table (step S21).
21b). If the entry does not exist (step S21c), the process ends assuming that no edit data exists (step S21m). If an entry exists (step S21c), it is checked whether an address or an offset position is stored in the address 8b of the edit data of the existing entry (step S2).
1d). If the address is stored, the editing data existing at the address is returned (step S211). If the offset position has been stored, the document file is moved according to the offset position (step S21).
e), the stamp information is read (step S21f).
The version number 17a stored in the stamp information is checked to determine whether the version number is equal to the version number of the software currently being processed or whether the version is convertible (step S21g). If the version is different from the version of the software that is currently performing the process and is not a convertible version, the process ends assuming that there is no edited data (step S21m). Next, the editing data is read (step S21i). The version number 17a stored in the stamp information read in step S21f is checked (step S21i). If the version number is different from the version of the software currently being processed (in step S21g, conversion is always possible in such a case). Version is assured), and the editing data is converted (step S21).
j) The address of the edited data read is added to the corresponding entry of the edited data management table (step S21k), regardless of whether the conversion is performed or not (step S21l), and the process ends normally (step S211).

(Other Embodiments) Although the document edited in the present embodiment is composed of two types of editing data, word processing data and graphic data, this is not limited to two types, and editing data of applications such as table editing, spreadsheets, graphs, etc. Any kind of edit data may be added, that is, any kind of edit data may be added.

2. In the display procedure of the present embodiment, all the frames existing on the background page are displayed. However, it is also possible to prevent all or any frames from being displayed according to the specification of the user who performs the editing operation. In that case, the time required for display is further reduced.

3. In the display procedure of the present embodiment, all the edit data existing on the background page or the frame are displayed, but all the edit data or only the edit data of any application is not displayed according to the specification of the user who performs the edit operation. It is also possible. In that case, the time required for display is further reduced.

4. In the present embodiment, the information stored in the stamp information is only the version number. However, in addition to the version number, information of the application that created the edited data is also stored in the stamp information, and the edited data of a different application is stored. It is also conceivable to make it possible to read if it can be converted.
