Abstract

PURPOSE:To protect important display data without erasing when the data need to be scrolled by leaving display data with a protection attribute on a display screen and erasing display data which does not have the protection attribute from the display screen when the data are scrolled. CONSTITUTION:When the entire screen is already used for display at the time of the scrolling of display contents corresponding to screen data inputted to a display device 3, lines which are scrolled disappear from the display screen, but the important data which need to be displayed at all times are given the protection attribute and then left on the screen irrelevantly to the scrolling. Thus, the scrolling process is performed and the protected data are accumulated in the upper part of a screen memory. When the protected data occupies the majority of the display screen and an area for data display in a normal process decreases to interfere with the execution, a warning message is displayed and an operator inputs a command which make the protected data on the screw invalid to display the specified protected data which are made invalid.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device having a display device for displaying information.

[0002]

2. Description of the Related Art In a data processing device for performing processing of displaying data input from a data input device such as a keyboard or processed data on a display screen of a display device,
When displaying new display data on the display device, if the display data on the display screen is already full, the screen is scrolled and the oldest display data is erased from the display screen, thereby creating a display area on the display screen. After securing it, the new display data was displayed.

When the user wants to confirm the amount of internal memory available in the data processing device, the process being executed is temporarily suspended and the amount of internal memory available from the keyboard or the amount of memory in use. I input the display command, etc., and confirmed that the result was displayed on the display screen.

[0004]

However, when scrolling occurs when new display data is displayed on the display device, the display data erased from the display screen is important and there is a case where it is desired to keep it.

When the user wants to check the amount of internal memory available in the data processing device, the process being executed is interrupted each time the internal memory amount available from the keyboard or the like It was troublesome to input a display command for the amount of memory in use and display the result on the display screen. Further, when the memory is insufficient, the user does not know that it is in that state, so that it is not possible to prevent the occurrence of an error such as inexecutability due to lack of memory by starting a certain program.

The present invention has been made in view of the above conventional example. For example, when scrolling is required for display data on the screen of a display device, important display data can be protected without being erased. An object is to provide a data processing device.

【Example】

(Embodiment 1) FIG. 1 is a block diagram showing the configuration of a data processing apparatus according to a first embodiment of the present invention. The configuration of the first embodiment will be described below with reference to this figure. .

A host computer 1 is connected so as to be communicable with the terminal device 2 via a predetermined interface.

The terminal device 2 connects the input device 4 and the display device 3 via a predetermined interface. An input device 4 is used to input data, a redisplay instruction, an erase instruction, etc. to the terminal device 2. The screen memory 2a provided in the terminal device 2 displays screen display data. In the data processing device thus configured, the screen memory 2a
The screen data of is displayed on the display device 3.

When scrolling the display contents according to the screen data input to the display device 3, if the entire screen is already used for display, the scrolled line disappears from the display screen. Among the data displayed on the screen,
There is also important data that you want to display at all times, in which case it remains on the screen regardless of whether it is scrolled. In this way, in order to protect the display on the screen, by specifying the range of data to be protected and giving the protection attribute to the specified range, it is possible to distinguish whether or not the data may be erased when scrolling. To do so. If the protection attribute is active, overwriting is prohibited or the protected data is prevented from being lost from the screen memory by scrolling.

When scrolling, the terminal device 2 checks the protection attribute of the line to be scrolled, skips the line having the protected data, and checks the next line. Also,
If there is no protected data in that row, that row is deleted.

As the processing is performed by such a procedure, the protected data is accumulated above the screen memory.

Further, since the protected data occupies most of the display screen and the area of the data display in the normal processing is reduced, the warning message is displayed when the execution is hindered. Then, from the operator, the input device 4
By inputting a command to invalidate the protected data on the screen, the display of the protected data designated as invalid is invalidated, and the data display area in the normal process is increased to enable execution.

The processing of the data processing apparatus of this embodiment will be described below with reference to the flow charts shown in FIGS.

FIG. 2 is a flow chart showing an example of the procedure for setting the protection attribute of the display data of the data processing apparatus of this embodiment.

At step A1, a range area of data to be protected is designated.

At step A2, the attribute of the protected data is set to the data in the designated range area.

FIG. 3 is a flow chart showing an example of the re-display processing procedure of the protection attribute data in the data processing apparatus of this embodiment.

At step B1, it is judged whether or not a command for redisplaying the protected data is inputted from the input device 4.
Then, if it is input, the process proceeds to the process of displaying the protected data, that is, step B2 and thereafter. If not entered,
The process ends without doing anything.

At step B2, the attribute of the protected data set in the screen memory is searched.

In step B3, it is checked whether or not there is protected data having the attribute of protected data. And
If there is no protected data, the process ends. If there is, the process proceeds to step B4 for displaying.

In step B4, the redisplay program 2b displays the data having the protection attribute on the display device 3.

FIG. 4 is an example of a flowchart showing a processing procedure regarding protected data when the screen is scrolled in the data processing apparatus of this embodiment.

In step C1, if the display device 3 scrolls one line, it is determined whether or not the first line disappears from the screen memory 2a. If it disappears, the process related to the protected data is performed, and therefore, the process proceeds to step C2 and thereafter. If it does not disappear, the process ends.

In step C2, it is judged whether or not the pointer indicating the lost line is "0". If "0", the process proceeds to C3 and thereafter, and if not "0", the process proceeds to C5.

At step C3, it is judged whether or not there is protected data in the line indicated by the pointer. Then, if there is protected data, the process proceeds to step C4 and thereafter. If not, the line indicated by the pointer may be erased, and the process proceeds to step C11.

At step C4, the pointer indicating the erased row is incremented by 1 so that the pointer indicates the next row.

At step C6, it is checked whether or not the pointer exceeds the allowable range of the screen memory.
Here, if the pointer exceeds the allowable use range, the line cannot be displayed on the screen. Therefore, in that case, the process proceeds to step C7 for outputting a warning message. If the allowable range of use is not exceeded, the line can be output to the screen. Therefore, the process proceeds to step C8 and subsequent steps for performing normal processing of checking the protected data and outputting to the screen.

At step C7, a warning message indicating that the pointer exceeds the allowable range of the screen memory is displayed on the display device 3.

At step C9, the protected data attribute associated with the protected data in the screen memory is cleared. The selection of the protection data to be cleared may be designated by the operator from the input device 4, or the protection data to be automatically cleared may be selected. As a method of selecting the protected data to be automatically cleared, for example, the operator may give a priority value of importance as an attribute of each protected data, and when selecting, the one with the lower priority may be selected. . Then, the display of the cleared protected data is invalidated, and the data display area in the normal process is increased to make it executable.

At step C10, the pointer indicating the erased row is cleared.

At step C11, the top row of the memory is erased, and the process ends.

At step C5, it is checked whether or not there is protected data at the pointer destination indicating the lost row. Then, if there is protected data, the process proceeds to step C4. If not, the line may be erased, and the process proceeds to step C12.

At step C8, it is checked whether or not there is protected data at the pointer destination indicating the lost row. If there is protected data, the process returns to step C4 to check the next line. If not, the line may be erased, and the process proceeds to step C12.

At step C12, the line indicated by the pointer is erased. Then, the process ends.

Although not shown in the figure, the user can freely set the value of the allowable use range of the screen by the protected data.
It can be set from the input device 4 or the like.

An external storage device is added to the terminal device 2,
When a warning message is displayed when the protected data is lost, add a switch to erase or save the protected data and select save to automatically register the protected data in the external storage device, or as necessary. Accordingly, by outputting the data to the printer and then deleting the protected data from the screen, important data can be saved more reliably.

Further, even if the screen disappearance data which cannot be redisplayed conventionally, is judged by the user to be important,
They can be protected and redisplayed easily and efficiently.

The switch can be realized, for example, by inputting an instruction from the input device 4 in advance and setting the information in the internal memory.

As described above, according to this embodiment, the following effects can be obtained. That is, when new display data is displayed on the display device, when scrolling occurs, or when display data erased from the display screen is important, protection can be performed by appropriately adding a protection attribute.

(Embodiment 2) In the second embodiment of the present invention,
An example of a method that can more easily notify the user of the usage status of the internal memory of the terminal device 2 will be shown.

The processing procedure of the second embodiment will be described below with reference to the flow charts shown in FIGS.

FIG. 5, the display device 2 in the terminal device 2,
That is, it is a flowchart showing an example of a basic parameter setting procedure for controlling the brightness of the display in accordance with the usage status of the internal memory.

In step D1, the user sets the number of steps for decreasing the brightness of the display in advance, for example, three steps.

In step D2, it is set what percentage of the total brightness is to be decreased in each of the set number of steps.

In step D3, each step is made to correspond,
Set the memory consumption.

Next, FIG. 3 is a flow chart for explaining an example of a processing procedure for controlling the brightness of the display device 2, that is, the display, in the terminal device 2 in accordance with the use condition of the internal memory.

At step E1, the current capacity of the internal memory is checked.

In step E2, it is judged whether the used memory capacity is 70% or more of the entire memory. If it is 70% or more of the entire memory, the process proceeds to step E3. If it is not 70% or more of the entire memory, the process proceeds to step E8.

At step E3, it is judged whether the used memory capacity is 80% or more of the entire memory. If it is 80% or more of the entire memory, the process proceeds to step E4. If it is not more than 80% of the total memory, the process proceeds to step E5.

At step E4, it is judged whether the used memory capacity is 90% or more of the entire memory. If it is 90% or more of the entire memory, the process proceeds to step E6. If it is not more than 90% of the total memory, the process proceeds to step E7.

In step E8, since the available memory capacity is sufficient, the display brightness is set to the default.

In step E5, the brightness of the display is set to the brightness which is one step lower than the default, which is preset in the processing procedure of FIG.

In step E7, the brightness of the display is set to the brightness which is preset by the processing procedure of FIG.

In step E6, the brightness of the display is set to the brightness preset by the processing procedure of FIG.

An example of the processing procedure for controlling the brightness of the display in accordance with the usage status of the internal memory has been described above. However, instead of lowering the brightness of the display, a color is selected and its hue is strengthened. Good. By doing so, it is possible to prevent the display from becoming difficult to see due to the decrease in the brightness of the display.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

As described above, according to this embodiment, the following effects can be obtained. That is, in the present embodiment, when it is desired to check the memory usage status, the user does not need to perform processing such as inputting a command for checking the memory usage status after interrupting the temporary processing, and the Since the usage status of the memory can be checked from the display screen, when the memory is insufficient, you do not know that it is in that state, so you can start a program and prevent errors such as inability to execute due to insufficient memory. The memory can be used effectively.

[0061]

As described above, according to the present invention, for example, when it is necessary to scroll the display data on the screen of the display device, important display data can be protected without being erased.
