Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing function of a text editor, in which an input area is set to a designated portion of text being edited, and the inside of the input area is set as an editable or non-editable area, and the outside of the input area is set. The present invention relates to a text editor having a text edit protection function for preventing uneditable text from being accidentally deleted or changed as an uneditable or editable portion.

[0002]

2. Description of the Related Art A conventional text editor manages each text to be edited by a character data string and a line number indicating the position of the character data string to prevent a reduction in editing time or a decrease in processing performance due to a memory constraint. I am trying to In Japanese Patent Laid-Open No. 2-16648 as an example, in addition to managing the text by the text and the line number of each record, the area for storing the record of the text is managed by the chain, and the editing result of the text is stored in the entire text. A method for preventing the influence and shortening the editing time is disclosed.

Further, in Japanese Patent Laid-Open No. 1-306954, a text file in which a text and a line number of the text are integrated is limited to the text size to be edited due to the memory capacity, and the processing performance is deteriorated. It is disclosed that a file and a line number file are separately provided and the line number file is placed in a memory to reduce the number of input / output times to and from the auxiliary storage device and improve the processing performance of the editing process.

In both of the above-mentioned editing processes, the text to be edited is treated in the same way as a part of a series of connected texts in any place on any line, so that the edit object or the editing range is limited to perform editing. I can't do it.
Usually, when creating a standard text, the text may be created by modifying a predetermined part of the template text. In such a case, limit the part to be edited,
It is effective in text protection to limit the editing process to that part. In the above-described conventional text editor, since the entire read text is the editing target, a portion that is not the editing target may be mistakenly deleted or changed.

[0005]

[Problems to be Solved by the Invention] Is it possible to specify an editable area in a text and limit the editable area to that?
Alternatively, it is possible to select whether or not the area other than that area can be edited. Then, by automatically incorporating the edited result into the original text, the text is prevented from being destroyed due to an erroneous operation.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is for a text editor to set an editing work area different from the editing work area of the text itself, corresponding to a designated portion of the text.
