Abstract

PURPOSE:To shorten the time required for displaying an object list data by clearing storage position information storing 1st data obtained by dividing the total list data into N parts, and at the time of sequentially displaying the divided list data on a display device, starting the display of the list data from respective N-divided position by means of key input. CONSTITUTION:The tile display system is provided with a list data ordering means 1 for rearranging plural list data 5a stored in a storage means 5, a positional information extracting means 2 for reading the list data 5a and registering nine storage positions from 1/10 to 9/10 of the whole list data in a pointer table 5b, a nearby positioning means 3 for obtaining the storage position of list data from the pointer table 5b on the basis of control information specified from a keyboard 6 and displaying the list data stored on the position on its screen, and a sequential display means 4 for displaying the list data on a display device 7 on the basis of an inputted scroll request. Thus, the retrieving time can be shortened even if the volume of data is increased.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for displaying list data arranged in a logical order, in particular, the vicinity of target data is located by an input means, and the vicinity of the target data is located in the logical order from the vicinity. The present invention relates to a list data display method that displays target data by tracing the data.

[Conventional technology]

Conventionally, the display method for this type of list data is to specify the physical location where the list data is stored and display the list data, but the method is to attach a search key to the list data and specify the search key to display the list data. , a direct instruction method in which a specific character string contained in the list data is specified and the list data containing the specified character string is searched and displayed, or the list data is displayed from the beginning on the display device. This was a sequential display method in which the data was displayed on the screen and the screen was scrolled to perform a visual search until the necessary display data was displayed.

[Problem to be solved by the invention]

In the conventional direct display method of list data described above, it is necessary to clarify the physical memory aspect of the target list data, add a search to the list data, or find the exact character string contained in the target display data. The downside is that you need to know.

Furthermore, the sequential display method in which all display data is displayed on the screen from the beginning and the screen is scrolled has the disadvantage that it takes a lot of time to search when the amount of data increases.

[Means to solve the problem]

According to the present invention, there is provided a list data ordering means for rearranging list data stored in a storage device, and a position information extraction means for extracting a storage position of specific list data from among the list data rearranged on the storage device. and sequential display means for displaying the specific list data on a display device starting from the list data.

The present invention, for example, rearranges all display data in a logical order, then directly displays the vicinity of the target display data, such as 3/10ths and 7/10ths from the front, and from there. To provide a list data display method in which target display data is displayed on a screen using a sequential display method.

〔Example〕

Next, the present invention will be explained in more detail with reference to the drawings showing one embodiment of the present invention.

Referring to FIG. 1, the method of displaying list data according to an embodiment of the present invention is to display a plurality of list data 5a stored in a storage device (main storage device or external storage device) 5.
a list data ordering means 1 for rearranging the data by sorting; and a position information extraction means 2 for reading the list data 5a and registering nine storage positions from 1/10 to 9/10 from the front of all displayed data in a pointer table 5b. and a nearby positioning means 3 that obtains the storage position of the list data from the pointer table 5b based on control information specified by the keyboard 6 and displays the list data stored at that position on the screen, and a scroll request inputted from the keyboard 6. The display device 7 is comprised of a sequential display means 7 for displaying the next list data or the previous list data on a display device 7 depending on whether the scrolling is forward scrolling or backward scrolling.

Referring to FIG. 2, the processing in the list data ordering means 1 consists of step 21 of rearranging the list data by sorting.

Referring to FIG. 3, the process in the position information extracting means 2 consists of step 31 of registering the list data storage positions of each of the 10 equal parts of the total number of risk data in the pointer table.

Referring to FIG. 4, the processing in the neighborhood position creation means 3 includes a step 41 of inputting control information from the keyboard, a step 42 of extracting storage device information of the list data from the pointer table, and a step 42 of extracting the storage device information of the list data from the pointer table. Step 43 of displaying the list data on the screen
It consists of

Referring to FIG. 5, the sequential display means 4 performs a step 51 of inputting a scroll request from the keyboard, a step 52 of determining a forward scroll request, a step 53 of displaying the next list data on the screen, and a step of determining a backward scroll request. 54, and step 55 for displaying the immediately preceding list data on the screen.

In the above explanation, it was explained as 10 equal parts, but any N
It is clear from the above explanation that it may be equally divided.

〔Effect of the invention〕

As explained above, according to the present invention, list data is stored in a storage device, and the storage location information of the list data obtained by dividing the total number of list data into N equal parts is revealed, and the list data is stored. When sequentially displaying on the display device, the display can be started from each position divided into N equal parts by keystrokes, so that the time required to display the target list data on the screen can be shortened.
