DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram for implementing an embodiment of the present invention. As shown in FIG. 1, this embodiment comprises a file editing unit 2, a main storage unit 7, a file access unit 10, and an external storage device 13. The file editing unit 2 includes an editing range designation data input changing unit 1 and an editing unit. The external storage device 13 includes a range designation data read / write unit 3, a range designation code setting unit 4, an edit permission determination unit 5, and a range designation code deletion unit 6, and the external storage device 13 includes an edit range designation data storage file 11 and an edit target file 12. have.

When the file editing unit 2 is activated to start editing the edit target file 12, the edit range designation data read / write unit 3 stores the range designation data relating to the edit target file 12 in the edit range designation data storage file 11. Whether or not it exists is checked, and if it exists, the editing range designation data 8 for the file 12 to be edited is read into the main storage unit 7 via the file access unit 10.

The edit range designation data input change section 1 displays the contents of the read edit range designation data 8 in the main storage section 7 if any, and inputs new data only when changing the data, and the predetermined format is entered. Converted to and edit range specification data 8
To update. If the data designating the editing range does not exist in advance, the editing range designation data input changing unit 1 does not display anything, and the data designating the new editing range is converted into a predetermined format and stored in the main storage unit 7. Edit range specification data 8
Enter as.

The range designation code setting unit 4 reads the data 9 of the edit target file from the edit target file 12 through the file access unit 10 onto the main storage unit 7, and the editor is given write permission for the edit target file 12. Then, according to the editing range designation data 8, a code indicating that editing is prohibited is added to the beginning of each line outside the editing range designation.

The file editing unit 2 executes the editing only when the editor is given the write permission for the editing target file 12. At the time of the editing, the head of each line of the data 9 of the editing target file is The edit permission judging section 5 checks whether or not there is a code for prohibiting editing, and if the code to be edited has a code at the beginning, prohibits any editing action on the line. However, only when a certain new line is inserted between consecutive lines to which a code indicating that editing is prohibited is added, the edit permission judgment unit 5 displays a warning sentence and does not prohibit editing. . This newly inserted line is to be edited because no code for prohibiting editing is added. When the editing range is changed during editing, the editing range designation data input changing unit 1 updates the editing range designation data 8.

When the editing of the data 9 of the file to be edited is completed and the file editing section 2 is to be terminated,
The range designation code deletion unit 6 uses the data 9 of the file to be edited.
A code indicating that editing is prohibited is added to the external storage device 13 through the file access unit 10.
Output to the file 12 to be edited. Then, the edit range designation data read / write unit 3 writes the edit range designation data 8 in a predetermined format into the edit range designation data storage file 11 on the external storage device 13 via the file access unit 10. The file access unit 10 reads data from the external storage device 13 into the main storage unit 7, and writes data from the main storage unit 7 to the external storage device 13.

Next, the operation of this embodiment will be described.

FIG. 2 is a flow chart showing the flow of processing in this embodiment, and FIG. 3 is a flow chart for connecting to the connectors A and B of FIG.

First, the file editing unit 2 is activated to start editing. The name of the file to be edited 12 is passed as a parameter to the file editing unit 2 (step 1). The range designation data storage file 11 is searched for the range designation data relating to the file to be edited (step 2). The search result is judged and the next processing is determined (step 3). Then, when the range designation data regarding the file to be edited exists in the range designation data storage file 11, it is read into the main memory 7 through the file access unit 10 (step 4), and the range designation data 8 read into the main memory 7 is displayed. (Step 5).

Next, it is judged whether the range designation data is updated or a new input is made, and the next process is determined (step 6). If the range designation data is updated or newly input, the new range designation data is input (step 7), the range designation data 8 is updated with the new range designation data, or the range designation data 8 is newly created ( Step 8).
Then, the data of the file to be edited 12 is read from the external storage device 13 into the main memory through the file access unit 10 (step 9).

Next, it is determined whether the editor has write permission for the file to be edited, and the next process is determined (step 10). If the write permission is not given to the editor, only reference to the data of the file to be edited is permitted (step 11). In addition, when the editor is given the above-mentioned write permission, FIG.
The processing from step 12 to step 25 shown in is performed. First, it is determined whether or not the range designation data 8 is in the main memory, and the next process is determined (step 12). If there is range designation data 8, a code indicating that editing is prohibited is added to the data 9 of the file to be edited according to the range designation data (step 13). Then, an edit command is input, and when an end command is input, processing for ending is executed. When the processing of one edit command is completed, this judgment is returned (step 14). If a command other than the end command is input, it is interpreted as an edit command, and if there is data passed to the edit command, it is interpreted to determine the edit target range (step 15).

Next, it is judged whether or not a code indicating write prohibition is added to the edit target range, and the next process is determined (step 16). If a code indicating write protection is added to the edit target range, it is determined whether or not the edit command is an insert command and the next process is determined (step 1).
7). Then, when the edit command is an insert command, a warning message is displayed to the effect that the write is prohibited in the edit range (step 18). If the code indicating the write prohibition is not added to the edit target range, the edit command is executed as it is, and the process returns to step 14 (step 19). If the insert command is executed,
Since the range to be edited changes, it is determined whether the range designation data is updated according to the number of inserted rows, and the next process is determined (step 20). When the insertion is performed, the range designation data is updated (step 21).

When the editing end command is input in step 14, it is determined whether the range designation data 8 exists in the main storage unit 7, and the next process is determined (step 22). When the range designation data 8 exists in the main storage unit 7,
The code indicating that writing is prohibited is deleted from the data 9 of the file to be edited (step 23), and the range designation data 8 is written to the edit range designation data storage file 11 via the file access unit 10 (step 24). Further, when the range designation data 8 does not exist in the main storage unit 7, or when step 24 ends, the data 9 of the file to be edited is transferred via the file access unit 10 to the external storage device 1.
3 is written in the file 12 to be edited (step 2
5). When step 25 or step 11 ends, the editing ends (step 26).

By thus specifying the variable target range of the edit target file, editing outside the specified range is prohibited.

In this embodiment, the code indicating prohibition is added to the head of each line outside the specified range. However, a code indicating that the prohibition range starts is added to the head of the first line outside the specified range. , A code indicating the end of the prohibited range may be added to the end of the last line outside the specified range, or a code permitting editing within the editing range may be added instead of the above-mentioned code indicating the prohibited range. Good. Further, the edit range designation data storage file need not be used if a range is designated each time editing is performed and the file is stored in the main storage unit 7.

[0021]

As described above, according to the present invention, the editor can specify the edit target range of the edit target file, and the range that does not need to be changed or the range that cannot be changed can be edited. By excluding it from the range,
The contents outside the editing range will not be inadvertently deleted, changed, or added with unnecessary data. Therefore, the editor can concentrate on the edit target range and can reduce mistakes that the editor does not notice.
