Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a data display system that hides unnecessary portions and displays only necessary portions when displaying data on a display device, and designates data to be displayed on the same line in the display device. A data display system for displaying data composed of a plurality of lines of the same format on a display for the purpose of simultaneously displaying a portion of the data, wherein a start position and an end position of a portion of the data to be displayed in the horizontal direction are determined. Input means for inputting a mark for designating, and display means for outputting, to a display, data located between a horizontal start position and an end position of data specified by the mark input by the input means. It comprises so that it may have.

[Industrial applications]

The present invention relates to a data display system.
The present invention relates to a data display system that hides unnecessary portions and displays only necessary portions when displaying data on a display device.

Display of data in a data processing device is often performed via a display device.

[Conventional technology]

In most cases, the size of the display screen of the display device currently used is 80 columns in the horizontal direction (the size of one line). However, the data to be displayed on the screen (horizontal size) is rarely 80 columns or less, and it is often impossible to simultaneously display the entire data on the same line. On the other hand, when the user refers to the data, the data extending in the horizontal direction of the screen (the same line)
It is more likely to refer to the left end and right end simultaneously than to refer to the data at the left end and the data in the middle of the row at the same time.

Therefore, conventionally, when the data has 80 columns or more, a necessary portion of the data is referred to by using a horizontal scroll function of the screen. That is, for example, a screen including a left end portion in one line is displayed, and thereafter, the screen is scrolled in a horizontal direction according to a user's instruction, and a screen including a right end portion is displayed. Therefore, the data on the same line on the display screen is displayed twice, and the user has also referred to the necessary part of the data twice.

[Problems to be solved by the invention]

According to the above-described related art, as the size of data displayed (to be displayed) on the same line increases, the number of times of scrolling needs to be increased in order to refer to the leftmost and rightmost data. For this reason, there is a problem that the operability of the data processing device is deteriorated.

Further, according to the above-described prior art, it is impossible to simultaneously display and refer to the left end and right end portions of the data on the same line. For this reason, if it is absolutely necessary to refer to them at the same time, print one of them first (hard copy)
Then, it is necessary to scroll the screen in the horizontal direction and print the other, and refer to the left and right ends of the data using the printed matter. Therefore, for simultaneous reference of data,
In addition to scrolling the screen, multiple printing is required,
As described above, there is a problem that the operability of the data processing device is deteriorated.

The present invention focuses on the fact that a plurality of lines configured in the same format exist in a display device, and enables a data display system to simultaneously display a designated portion of data to be displayed on the same line. The purpose is to provide.

[Means for solving the problem]

FIG. 1 is a block diagram of the principle of the present invention, showing a data processing device according to the present invention.

In FIG. 1, 1 is a processing device, 2 is a display device, 3
Is an external storage device, 4 is a data processing unit, 5 is a display control unit, and 6 is a data reading unit.

The processing device 1 comprises a central processing unit (CPU) and a memory, performs data creation and processing, controls the display device 2 for displaying data, and externally stores and reads (reads) data. The storage device 3 is controlled.

The display device 2 is for displaying data. For example, the display device 2 displays data stored in the external storage device 3 and data processed by the data processing unit 4.

The external storage device 3 stores data created by the processing device 1 or another data processing device. This data is in a predetermined format suitable for storage in the external storage device 3 or the like.

The display control unit 5 displays data on the display device 2 and receives an instruction for displaying data. This instruction is given, for example, from a keyboard (not shown) by a user input or in the form of a command.

The data reading unit 6 reads data from the external storage device 3 and sends the data to the data processing unit 4.

The data processing unit 4 processes the read data according to the instruction received by the display control unit 5 to create data for display, and sends the data to the display control unit 5.

[Action]

The data processing unit 4 omits (deletes) parts of the read data other than the part (display part) determined by the instruction according to the instruction received by the display control unit 5.
By doing so, the size of the read data is compressed.

The data processing unit 4 also converts the predetermined portion from the predetermined format as described above into a format that can be displayed on the display device 2.

As a result of such data processing, only the predetermined portion can be displayed on the display device 2. Therefore, the instruction is information that defines the display range of the data.

As described above, data for display is created. For example, if the data to be displayed on the same line is instructed to specify the left and right edges as the display range, the data for this display shall consist of only the left and right edges, and the middle The part is omitted.

When such data for display is displayed on the display device 2 by the display control unit 5, first, the left end portion is displayed at the left end of the row, and subsequently, the right end portion is displayed. That is, the middle part between the left end and the right end is omitted, and this part is not blank when displayed on the screen. By compressing the data by omitting the parts other than the part specified by the instruction, the part specified by the instruction can be displayed at the same time.

〔Example〕

(A) Description of an embodiment FIG. 2 is an explanatory diagram of an embodiment, showing a data processing device.

In FIG. 2, 7 is a screen memory, 8 is a keyboard, 41 is an analysis unit, 42 is a BNDS creation unit, 43 is a data compression unit, 44 is a conversion unit,
Reference numeral 51 denotes a terminal processing reception unit, and 52 denotes a screen display unit.

In this embodiment, an instruction for displaying data, that is, information for defining a display range is input to a keyboard (or input device) 8.
Is an example given through

The screen memory 7 is a part of the memory of the processing device 1,
It includes a primary storage area for data, a storage area for processed data, a storage area for non-display column data, and a storage area for screen display format data. These areas are used by the data processing unit 4 to create data for display. The data read from the external storage device 3 is stored in the primary storage area of the data. The data for display is stored in the storage area of the screen display format data, and is referred to by the screen display unit 52 for display on the display device 2.

The keyboard 8 is shown as an example of an input device, and is provided as a terminal along with the display device 2. In this embodiment, information defining a display range (required portion of data) is input by using an input device such as a keyboard 8 while referring to the data once displayed on the screen. Accordingly, this information is information for distinguishing data displayed on the same line into a displayed portion (display column) and a non-displayed portion (non-display column) in column units.

For this reason, the information can be directly provided by designating the non-display column (see another embodiment).
However, even in such a case, there is no difference in distinguishing the data between display and non-display in the display processing, so it can be said that the display columns are indirectly defined. Therefore, in the present specification, even if the information is given in a form of designating a part that is not displayed, the “displayed part” is replaced with the “information (instruction for data display)”.
The "portion not determined" is referred to as "the portion other than the portion specified by the information".

The analysis unit 41 tabulates information relating to the non-display columns from the information defining the display range for a plurality of data, and accumulates the information in the non-display column data accumulation area of the screen memory 7. That is, for a plurality of (multiple rows) data, the non-display columns are represented by rows and columns (digits).

The BNDS creating unit 42 creates data for displaying the display row (BNDS) of the non-display column on the display device 2.
This data is in a format that can be displayed on the display device 2 and is stored in the storage area of the screen display format data in the screen memory 7. This data is displayed on the display device 2 together with the display columns. As a result, it is possible to confirm the information defining the display range.

The data compression unit 43 omits (deletes) the non-display columns from the read data based on the table relating to the non-display columns, compresses the data (the size, that is, the number of columns), and processes the result in the screen memory 7. The data is stored in the data storage area. For this purpose, the data compression unit 43 refers to the primary storage area of the data in the screen memory 7 and the storage area of the non-display column data.

The conversion unit 44 converts the compressed data stored in the processing data storage area into data in a format that can be displayed on the display device 2 and generates the data for display, and stores the screen display format data in the screen memory. Accumulate in the area. That is, image data is created by referring to a character generator or the like.

The terminal process receiving unit 51 receives a process from an input device such as the keyboard 8 of the terminal, and passes control to the corresponding process. For example, information for defining a display range is received, and control necessary for data processing is performed.

The screen display unit 52 displays the display data stored in the storage area of the screen display format data in the screen memory 7 on the display device 2.

 FIG. 3 is a diagram showing data before processing.

The external storage device 3 is, for example, a DA such as a magnetic disk device.
It consists of SD (Direct Access Storage Device). In the external storage device 3, data is stored in record units.

One record is information to be displayed on the same line at the time of display on the display device 2. Hereinafter, one record will be described as one data.

In FIG. 3, the number of columns is shown in order to indicate the size of one piece of data, such as “〜... 1... The illustration from the 31st column to the 89th column is omitted. In this case, the size of one data is 103 columns in terms of the number of columns, which is larger than the size of one column of the display device 2 of 80 columns. The number of columns is not stored in the external storage device 3 together with the data.

Such data is represented in a predetermined format such as an ASCII code, and keeps this format until it is converted by the conversion unit 44.

FIG. 4 is a data display processing flow, and FIG. 5 is a diagram showing an example of data display.

The terminal process receiving unit 51 receives a process input from the keyboard 8 of the terminal by the user.

When data reading is necessary for the processing, that is, when data stored in the external storage device 3 is used, the display control unit 5 notifies the data reading unit 6 of this fact.

The data reading unit 6 reads necessary (designated) data from the external storage device 3 and stores the data in the primary storage area of the screen memory 7 and the storage area of the processed data.

When data reading is unnecessary, that is, when new data is created by the user, the above processing is not performed.

The read or created data is displayed on the display device 2. That is, the conversion unit 44 converts the data into a format that can be displayed on the display device 2, and the screen display unit 52 displays this on the display device 2. This display is, for example, as shown in FIG. 3 (record 1: etc. are not displayed). In this case, it is impossible to simultaneously display the entire data having a size of 108 columns on the display device 2 in which one line has 80 columns.

Now, it is necessary to refer to the left end part “SHOUHIN” and the right end parts “URIAGE” and “RIEKI” of one piece of data at the same time, and the user inputs this fact. That is, the terminal processing receiving unit 51 receives a request for display processing from the keyboard 8 of the terminal by the user, in other words, information specifying a display range. As a result, the non-display request for a part of the column of the data is made.

The information defining the display range is input by positioning a pair of predetermined marks "<...>" in the range (column) to be displayed as shown in the second and sixth lines of FIG. . This input requires horizontal scrolling of the screen. This scroll function is provided in the display control unit 5.

When the request is made, the analysis unit 41 receives the notification from the terminal processing reception unit 51, analyzes the request, and creates a table relating to non-display columns in the non-display column data storage area of the screen memory 7. At this time, as shown in FIG. 5, when the display range as shown in the second line is specified for the data in the third line, this specification is applied to the line immediately before the next display range (the sixth line). Is valid and shall define the display range. Therefore, the second line defines the display range for the third to fifth lines, and the sixth line defines the display range for the seventh and subsequent lines (up to the last line). By performing such an analysis by the analysis unit 41, input of information defining the display range can be simplified.

 When the request is made, the above processing is not performed.

When the request is made, that is, when there is a non-display column, the BNDS creating unit 42 and the data compressing unit 43 know this from the notification from the terminal processing receiving unit 51, and perform the following processing.

If there are no hidden columns, the following processing is not performed.

The BNDS creating unit 42 stores data for performing the display “BNDS <...><…>” as shown in the second and sixth lines of FIG. 5 in a predetermined area of the screen display format data storage area of the screen memory 7. Create in the area. This processing is performed based on a notification from the terminal processing reception unit 51 or by referring to the storage area of the non-display column data in the screen memory 7.

The data compression unit 43 compresses the data in the primary storage area of the data in the screen memory 7 based on the table relating to the non-display columns, and stores the data in the storage area of the processed data in the screen memory 7. Since the data in the primary storage area of the screen memory 7 is left as it is, it is possible to cope with a change in information defining the display range without performing any processing or processing.

The conversion unit 44 converts the compressed data into a displayable format and creates data for display in a predetermined area of the screen display format data storage area of the screen memory 7. At this time, the table relating to the non-display columns is referred to, and the non-display columns are confirmed.

The screen display unit 52 displays data for display on the display device 2. The result of this display is as shown in FIG. In FIG. 5, reference numeral 21 denotes a screen, and "first line", "digit position" and the like are not displayed on the screen.

As is clear from the comparison with FIG. 3, in FIG. 5, in the third to fifth lines, columns 11 to 89 of the data in FIG. 3 are omitted, and the seventh to ninth lines are omitted. In FIG. 3, columns 33 to 89 of the data in FIG. 3 are omitted. These columns are set as non-display columns according to the information defining the display range on the second and sixth lines.

In addition, the display of the read data etc. in the processing,
The processing is performed by processing the data in the storage area of the processed data in the screen memory 7 in the same manner as in and. Therefore, the reading or creation of data is performed on both the primary storage area of the data in the screen memory 7 and the storage area of the processed data.

(B) Description of another embodiment FIG. 6 is an explanatory diagram of another embodiment.

This embodiment is an example in which information defining a display range is given as a command.

If the non-display column is known in advance, the display range can be defined by a command. That is, a command for indicating non-display (BNDS) and an operand indicating a non-display column are input to the command line. This operand provides information that defines the display range in a manner that specifies a non-display column.

For example, when the command BNDS (11:89 106: LAST) is input, the 11th column to 89th column and the 106th column to the last column of the data are set as non-display columns. Thus, the display shown in FIG. 6 is obtained. Also in this case, a predetermined mark "<...>" obtained by converting the command BNDS and the operand is displayed together with the data.

The display as shown in FIG. 5 can be obtained by designating the number of valid data of the command by the operand.

Although the present invention has been described with reference to the embodiments, the present invention can be variously modified in accordance with the gist thereof.

〔The invention's effect〕

As described above, according to the present invention, in the data display processing on the display device, the unnecessary portion of the data is hidden and only the necessary portion is displayed only by inputting the characters for the instruction. Can be displayed on the same line at the same time, so that the operability of the data processing device can be improved and the user can easily refer to the data.
