Description

[Detailed Description of the Invention] [Summary] In a processing device that edits a program or document, when displaying the program or document to be edited at a desired position in the edited data, a positioning assigned to the edited data in advance is used. By controlling the display positioning based on the relative positioning information in the area corresponding to the data mark or the total amount of edited data, you can easily and easily open the desired page as if you were inserting your finger into a book. This makes it possible to quickly position the display to be edited.

[Industrial application field]

The present invention provides an editing data display positioning control method;
In particular, the present invention relates to an edited data display positioning control method that enables the display positioning of edited data to be executed with a simple operation in a processing device that edits a program or document.

In recent years, increasing the productivity of programs executed by computers has become increasingly important. Therefore, it is desired to develop a design document that is easy to structure and a programming language that is similar to human language. Accordingly, it is desired to facilitate creation/editing of the design document or program.

[Conventional technology]

In conventional program development, design specifications are described using a flowchart or the like, and coding is performed while referring to the flowchart based on predetermined horizontal text rules depending on the programming language.

However, conventional flowcharts are not necessarily suitable for structured programs, and it is difficult to intuitively grasp the control structure of a program using flowcharts and source programs.

Therefore, the control structure is expressed with graphical symbols, the scope and level of control are clearly indicated with control lines, and a logic diagram that allows sufficient text to be written corresponding to the graphical symbols is created for the program. It is considered to be used for development and maintenance. This logic diagram can be used as a design document, and if the text part follows predetermined rules, it can also be used as a source program through translation processing, which improves program productivity. This is considered to be extremely useful for improving readability and maintainability.

However, if it takes time to create/edit a logic diagram, it increases the burden on the designer and reduces production efficiency, so it is important to create/edit such logic diagrams as easily and quickly as possible. It is hoped that

Therefore, a processing device is being considered that uses a computer to create/update logic diagrams while displaying them on a display screen. However, when editing or decoding programs or documents such as logic diagrams, it is necessary to frequently edit or update them. It is necessary to change the display of the data to be decoded.

Conventionally, when positioning the display of a program, document, etc., an operator memorizes the line number or page number of the desired display position in advance, and then instructs the display to be switched by specifying the line number or page number. Alternatively, the display could be positioned by scrolling by moving the cursor on the editing screen.

[Problem that the invention seeks to solve]

Conventionally, when editing a program or document, etc., when positioning the display at a desired position, the positioning is done based on a rough guide, such as positioning it approximately in the middle of the entire edited data, or positioning it toward the rear. It was not possible to specify. In addition, there is a problem that the operation is cumbersome because a person has to memorize line numbers, page numbers, etc. and specify them each time.

The present invention aims to solve the above-mentioned problems, and when editing a program or document, it is possible to open the desired page by inserting a bookmark in a book or by pressing and opening the page with your finger. Another object of the present invention is to provide a method that allows the display positioning of edited data displayed on a display to be easily performed, thereby improving the operability of an editing processing device.

〔Example〕

FIG. 2 is an explanatory diagram of display positioning processing according to an embodiment of the present invention, FIG. 3 is an example of a hardware configuration of a processing device according to the present invention, and FIG. 4 is a logical diagram creation process according to an embodiment of the present invention. An example of a display editing screen in the apparatus, FIG. 5 shows an overall processing configuration diagram according to an embodiment of the present invention, and FIG. 6 shows a processing explanatory diagram of an embodiment of the present invention.

First, according to the example shown in FIG. 2, a display positioning processing mode according to an embodiment of the present invention will be described.

As shown in FIG. 2A, the process related to the positioning mark is activated by placing the cursor 42 on the pattern C1 displayed on the display screen using a position pointing device such as a mouse and clicking the pattern. By this activation, the input frame 20 for mark processing is displayed.

For example, four marks M1 to M4 are prepared as positioning marks, and one of these marks is used as an operation target. In this example, mark M4 is displayed in a different color from the others and is the target of operation. This operation target is automatically selected according to the order of the operated marks, but it can also be changed by moving the cursor 42 and clicking.

When the cursor 42 is aligned with the "Set" area in the mark processing input frame 20 and clicked, the line number indicated by the current pointer CP in the edit data 19 is displayed on the currently valid positioning mark M4 of the operation target. Set. Note that this line number can also be set by inputting numbers from the keyboard.

When clicking in the "jump" area in the mark processing input frame 20, the display is positioned at the position to which the positioning mark M4, which is the operation target, is attached. Clicking in the "clear" area cancels the line number set in the positioning mark M4 that is the operation target.

“Previous mark” in mark processing input frame 20
When clicking in the area, display positioning is performed at the position of the positioning mark in front of the current pointer CP in the edit data 19. Second
In the example of the edit data 19 shown in FIG. 3C, display positioning is performed at the position of the positioning mark M4. Furthermore, when clicking in the "next mark" area, the display is positioned at the position of the positioning mark M2 after the current pointer CP.

In the display positioning according to the present invention, for example, a summing processing input frame 21 as shown in FIG. 2B is used. The summing process is started by placing the cursor 42 on the pattern C2 displayed on the display screen using a position pointing device such as a mouse and clicking. The summing processing input frame 21 displayed by this activation is provided with an area A1 for each of the positioning marks M1 to M4 and an area A2 for the current pointer CP.

If the total number of lines of the edit data 19 is, for example, 500 lines, the widths of the areas for each positioning mark M1 to M4 and the area for the current pointer CP are associated so that 500 lines is 100%, Therein, the positions of each positioning mark are displayed P1 to P4, and the position of the current pointer CP is displayed P5.

For example, the positioning mark M1 is assigned to the 50th line, so the position display P1 is
It is placed at 50/500 or 10% from the left edge. The display P5 of the current pointer CP is that the current pointer CP is currently on the 310th line, so
It is located 310/500 from the left edge.

When the cursor 42 is placed, for example, at position a shown in FIG. The line containing a shown in is displayed. When clicking at position b shown in FIG. 2B, the display is positioned at position b shown in FIG. 2C, which is the position of the positioning mark M2.

On the other hand, if you place the cursor 42 at position c shown in Figure 2B and click, this position will become the current position.
Since this is an area for the pointer CP, the display position is set by the following position calculation.

Now, if the x-coordinate of the 0% position is x ₀ , and the x-coordinate of the 100% position is x ₁₀₀ , then the length of 500 lines is (x ₁₀₀
−x ₀ ). If the coordinates of c indicated by the cursor 42 are x _c , then 500×(x _c −x ₀ )/
The line to be displayed is determined by calculating (x ₁₀₀ −x ₀ ). As a result, in the case of c shown in FIG. 2B, the position of c shown in FIG. 2C is displayed, and similarly, in the case of d shown in FIG.
The location will be displayed.
