Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display control device, and more particularly, in a display device of an electronic computer system, a control code for designating a color of a data to be displayed and a blink state is embedded in the data to control the display data. Create,
The present invention relates to a data display control device for editing and displaying.

[0002]

2. Description of the Related Art In a conventional data display control device, a change data receiving section 70 for receiving change data as shown in FIG.
2 and the data comparison unit 70 that compares the change data with the display data displayed on the display terminal when the change data is received.
4, and a display data creation unit 705 that embeds a control code in a necessary portion while transferring the display data to the editing area.
And a data display unit 70 for displaying the display data on the display terminal.
Have six.

When data is displayed using this data display control device, if the data being displayed is updated, the latest data is always displayed with blinking in the corresponding field.

The change data receiving unit 702 fetches the change data 707 received from the outside into an internal buffer and sets the data length, the display format and the like as internal parameters. Change data in this case, regardless of whether there is a change,
Receive data for all fields. FIG. 2 is a configuration diagram of display data. At this point, the control code is set only in the field whose display color needs to be changed.

In FIG. 3, the data comparison unit 703 and the display data creation unit 705 compare the already-displayed data 301 held internally and the update data 302 fetched by the receiving unit for the presence or absence of change for each field. Transfer to edit buffer.

Further, when the changed field is transferred to the editing buffer, the control code is inserted before and after the data corresponding to the field to be transferred is referred to the display data attribute table, and the corresponding display color and The edit data 303 is created by designating the presence or absence of blinking.

The already-displayed data 301 in FIG. 3 is the data currently being displayed, and the display field 1, the display field 2 and the display field 3 are displayed in the display color designated by the control code.

Similarly, the display fields 4 and 5 are displayed in the display color designated by the control code.

The update data 302 is change data, and the display field and the display field are updated display fields.

Whether or not each field has been updated is compared with each other. If the data do not match, it is determined that there is an update.

The data comparison unit 704 and the display data creation unit 705 first transfer the control code to the edit buffer. Next, the display field 1 of the already-displayed data 301 and the update data 302 is compared. Since display field 1 has not been updated, it is determined that there is no update and display field 1
To the edit buffer.

Further, the processing target is moved to the next display field and the already displayed data 301 and the updated data 302 are compared,
Determine whether there is an update. Since the display field has been updated, the value of the control code required for blinking is determined by referring to the display data attribute table before transferring to the edit buffer. To transfer the update field (denoted as'control code ') to the edit buffer, first transfer the control code to insert (in this case'), then the target display field, and then to stop blinking. The control code (in this case) must be transferred.

According to whether or not each display field is updated,
Display data is created in the edit buffer by repeating some of the above processes in all display fields.

The display field of the edit data 303 and the control codes before and after the display field are the control codes inserted by the above processing.

Edit data 3 created in the edit buffer by the data comparison unit 704 and the display data creation unit 705.
03 is displayed on the display device 710 by the data display unit 706.

After being displayed, the edited data 303 is transferred to the already displayed buffer as already displayed data.

FIG. 4 shows already-displayed data 401, updated data 402 and edited data 40 when further changes are made.
3 shows the data structure of 3.

The procedure for creating edit data by data comparison and data transfer is the same, but when comparing each field, the already-displayed data 401 and the update data 402 are used.
Since the data structure of No. 1 is different, when referring to the already-displayed data 401, it is necessary to compare the corresponding fields while skipping the inserted control code.

The data comparison section 704 has individual processing data for all data types, and performs processing while being aware of the control code inserted using that data.

[0020]

When the data being displayed is updated, a function for displaying the updated field in a display color corresponding to the change with blinking in order to improve the discriminability of the changed portion In realizing the above, in the above-mentioned conventional data display control device, when creating display data,
Since it is necessary to transfer each field of the displayed data and the changed data to the edit buffer while comparing them, and to insert the control code according to the presence or absence of the change, it takes time to process and the already displayed data buffer. However, there is a problem that three buffers, a change data buffer and an edit buffer, are required, and the resources of the main memory are squeezed.

A data display control device of the present invention, in a data display consisting of display data and a control code, a change data receiving means for receiving a data change, and a change data display when the change data is received. Data comparison means for comparing the display data displayed on the terminal,
Control code conversion means for converting the control code into a value corresponding to the display color and blink designation of the display data by referring to the display data attribute table regarding the changed data area, and data display means for displaying the display data on the display terminal .

[0022]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the data display control device of the present invention.

As shown in FIG. 1, the data display control device of the present embodiment includes a change data receiving section 1 for receiving change data.
02, and the data comparison unit 1 for comparing the change data with the already-displayed data displayed on the display terminal when the change data is received.
04, a control code conversion unit 105 that converts the control code of the updated field into a blink code, and a data display unit 106 that displays the display data on the display terminal.

The change data receiving unit 102 fetches the change data 107 received from the outside into an internal buffer and sets control codes before and after each field.

FIG. 5 is a configuration diagram of display data according to the present invention. In the figure, 501 is the data structure of already displayed data, and 502 is the data structure edited when the changed data is received.

By setting the control codes before and after all fields at the time of receiving the change data, the structure of the display data can be made the same regardless of whether or not all fields are updated.

By making the structure of the display data the same, there is no need to skip the control code by using the unique processing data for each data type as in the past, and the data of each field performed by the data comparison unit 104. Not only is the comparison much easier, but because the control codes have already been set before and after all fields, there is no need to transfer data or insert control codes using the edit buffer, greatly reducing the processing time. We were able to.

When comparing data, the data formats to be compared are always the same. Therefore, it is not necessary to use processing data unique to each data type, and processing for skipping the control code is also unnecessary.

Further, since the control code of the change data is converted into display data, the edit buffer which has been conventionally used is no longer necessary.

Reference numeral 501 in FIG. 5 is already-displayed data, and 502 is update data. Since both data have the same format, data comparison can be performed by a simple method of comparing the same offsets.

Also, when the update is performed, the display color and blink can be designated only by changing the values of the control codes before and after the update field.

In FIG. 1, the changed data and the already displayed data are compared. If the data is changed as a result of the comparison, the control code before the corresponding display field of the edit data 303 in FIG. 3 is changed to a value indicating blinking, and the control code after that is converted to a value indicating blinking stop.

Further, when the color designation of the change data is defined by referring to the display data attribute table, the control code before the corresponding display field is converted into the corresponding color designation code, and the control code behind is converted. Convert to the color specification code of.

In the update data 502, when the display field is updated, the display data can be created only by converting the control code and control code 'before and after the display field 2 into appropriate values for blinking and color designation.

[0036]

As described above, the data display control device of the present invention changes the display color or blinks to improve the visibility and clarify when the data displayed on the display terminal is changed. In the case of displaying as modified data, it was possible to edit the modified data buffer directly while editing the modified data from the modified data buffer while editing the modified data buffer. With such a configuration, the processing time for transferring the edited data can be shortened, and by editing the display format when the modified data is received, it becomes possible to easily compare the modified data with the already displayed data. Not only does it no longer have to perform processing using processing data that is unique to each type, but since the edit buffer is no longer needed, system resources can be used effectively. With a cormorant effect.
