Abstract

PURPOSE:To avoid such an inconvenient case where an edited document is inadvertently erased by providing a document editing flag register which shows that the document which is not stored in a recording device is stored in a document buffer. CONSTITUTION:A document editing part 12 judges that the key input shows a document editing process instruction and then turns on the flag of a document editing flag register 13. Then the part 12 applies an editing process to a document buffer 11. In case it is judged that the key input instructs the storage of the document data within the buffer 11, the flag of the register 13 is turned off. Then the part 12 stores the document data into the buffer 11. Furthermore if the key input shows the erasion of the contents of the buffer 11, a document calling part 14 judges whether the flag of the register 13 is kept on or not. If so, a signal is sent to a warning part 16 and a warning message is displayed on a display device 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device that protects created documents.

(Prior Art) In a conventional document creation device, a document once created can remain in a battery-backed RAM (document buffer) until the document is deleted. but,
For example, when you call up another document instead of the currently created document that has not been saved, when you select and call up the other document, the first document that has been written to the document buffer will remain unsaved. The newly recalled document will be written to the document buffer.

(Problem to be Solved by the Invention) In cases other than intentionally specifying document preservation as described above, there have been cases in which a created document is deleted without warning.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a document creation device that does not inadvertently erase edited documents.

[Structure of the Invention] (Means and Effects for Solving the Problems) The present invention is directed to documents that have been edited, such as newly created, configured, added, etc., and are not stored in a recording device such as a floppy disk drive. A document editing flag register is provided to indicate that the document is stored in the document buffer, and a warning is issued when the document in the document buffer is to be deleted according to the flag in the document editing flag register. This is to prevent the edited document from being deleted.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a partial circuit configuration of a document creation device according to the present invention, where 11 is a document buffer that temporarily stores a created or edited document, and 12 is a document buffer that directly edits the document buffer 11. a document editing section; 13, a document editing flag register that holds a document editing flag indicating whether the content of the document stored in the document buffer 11 has been edited by the document editing section 12; 14, a document editing flag register 13; 15 is a document storage unit that stores the document data stored in the document buffer 11 in a floppy disk device (not shown), which is an external storage device. ,1
6 is a warning unit that generates a warning message that the contents of the edited document buffer 11 will be deleted without being saved; 17 is a display device that displays and outputs the result of the document editing process and the warning message from the warning unit 16; 18 is the document editing section 12 and the document calling section 14 according to the instructed processing.
and a processing branching unit 18 that selects either one of the document storage unit 15 and executes an operation.

With the above configuration, its operation is as follows.

FIG. 2 shows the contents of processing during document editing, which is executed in response to input from the keyboard, which is not shown in FIG.

When a key is pressed manually from the keyboard, the document editing section 1
Step 2 first determines whether or not the key input is a document editing processing command as shown in step S01. If the determination result is YES, the contents of the document data stored in the document buffer 11 will be changed by editing processing, and a warning will be required when deleting the document, so the document will be edited in step SO2. The unit 12 turns on the flag in the document editing flag register 13. Thereafter, as shown in step S03, the document editing section 12 performs actual editing processing on the document buffer 11 corresponding to the key human power, and this operation is thus completed.

If it is determined in the above step SQL that the key input is not a document editing processing command, the process proceeds to step SO4, and this time whether the key input is an instruction to save the document data in the document buffer 11? It will be judged whether or not. If it is determined that storage is instructed, then the process proceeds to step SO5, where the document storage section 15 turns off the document editing flag register 13, assuming that a document deletion warning is not necessary. Thereafter, in step 806, the document editing section 12 performs actual storage processing on the document buffer 11 corresponding to the key manual power, and this operation is thus completed.

Furthermore, if it is determined in step SO4 that the key input is not a document storage processing command, the key input is assumed to be a process for deleting the contents of the document buffer 11, such as document recall, full text deletion, and multi-window cancellation. The process then proceeds to step S07. In step S07, the document retrieval unit 14 reads and determines whether or not the flag in the document edit flag register 13 is on. If it is on, a signal is sent from the document retrieval unit 4 to the warning unit 16. be done. At this time, data of a warning message such as "The document being created has not been saved" is sent from the document editing section 12 to the warning section 16. A warning message is generated and displayed on the display device 17 as shown in step SO8. Following this warning display, it is determined in step SO9 whether there is a key human power to instruct cancellation. If there is a key input, this means that the user does not want to erase the contents of the document buffer 11, so nothing is done and this operation process ends. After issuing this cancellation instruction, the user can save the document data in the -H document buffer 11, and then perform the initial keystroke again. When the document data is saved, the flag in the flag register 13 is reset to OFF. If there is no key to instruct the cancellation, this means that the user has recognized the warning and has determined that it is OK to delete the document data.The process then proceeds to step 510 to delete the document data in the document buffer 11. After completing the operation process, the process according to the initial key input is performed.

Note that if the document calling unit 14 determines in step SO7 that the flag in the document edit flag register 13 is not on but off, the document data stored in the document buffer 11 has not been subjected to editing or other processing. Therefore, it is determined that there is no need to display a warning message, and the process directly proceeds to step SIO. Then, in step SLO, the document data in the document buffer 11 is erased, and after this operation process is completed, the process according to the initial key input is performed.

Note that in the above embodiment, a warning to delete the document data stored in the document buffer 11 is issued by display output on the display device 17, but the present invention is not limited to this. You can also do this.

[Effects of the Invention] As detailed above, according to the present invention, by editing a document by creating a new one, configuring it, adding it, etc., a document that has not been saved in a recording device such as a floppy disk device is stored in the document buffer. A document editing flag register is provided to indicate when the document is being edited, and a warning is issued to the user when deleting a document in the document buffer according to the flag in the document editing flag register. It is possible to provide a document creation device that can always notify whether or not the storage process has been performed, and can prevent the edited document from being inadvertently deleted.
