Description

[Detailed Description of the Invention] [Summary] Regarding a data display processing method that hides unnecessary parts and displays only the necessary parts when displaying data on a display device, this invention specifies data to be displayed on the same line on the display device. The purpose is to simultaneously display the parts that have been a display control unit that receives instructions for displaying data and displays the data on a display device; and a data reading unit that reads the data from an external storage device. a data processing unit that processes the read data to create data for display, and the data processing unit converts the read data into the predetermined format according to instructions received by the display control unit. The data is compressed by omitting the part other than the part specified by the instruction, and the part specified by the instruction is converted into a format that can be displayed on the display device, and the data is displayed. The display controller is configured to display the data for display on the display device.
[Industrial Application Field] The present invention relates to a data display processing method. For more details. This paper relates to a data display processing method that hides unnecessary parts and displays only the necessary parts when displaying data on a display device. Display of data in data processing equipment. This is often done via a display device. [Prior Art] In most cases, the size of the display screen of currently used display devices is 80 columns in the horizontal direction (size of one line). but. Data that should be displayed on the screen (
(horizontal size) is rarely less than 80 columns, and it is often not possible to display the entire data in the same row at the same time. On the other hand, when the user refers to data, in the data extending horizontally (on the same line) on the screen,
It is more common to refer to the leftmost part of a row and the rightmost part at the same time, rather than to refer to the leftmost part of the row and the data part in the middle at the same time. Therefore, conventionally, if the data has 80 or more columns. The horizontal scroll function of the screen was used to refer to the required part of the data. That is, for example. A screen containing the leftmost portion of the l line is displayed. After this, the screen is scrolled horizontally according to the user's instructions. A screen including the rightmost part will be displayed. Therefore, data on the same line on the display screen was displayed twice, and the user had to refer to the necessary part of the data twice. (Problem to be Solved by the Invention) According to the prior art described above, as the size of data displayed (to be displayed) on the same line increases, in order to refer to data at the left end and right end. It is also necessary to increase the number of scrolls. As a result, there was a problem in that the operability of the data processing device deteriorated. Also, according to the prior art described above. It is impossible to display and refer to the left and right ends of data in the same row at the same time. For this reason. If you absolutely need to refer to both at the same time, print (hard copy) one of them first.
After this, you need to scroll the screen horizontally, print the other side, and use the printout to refer to the left and right edges of the data. Therefore, in order to refer to data simultaneously, it is necessary to print multiple times in addition to scrolling the screen. As mentioned above, there was a problem that the operability of the data processing device deteriorated. An object of the present invention is to provide a data display processing method that makes it possible to simultaneously display designated portions of data to be displayed on the same line on a display device. [Means for solving the problem] Figure 1 is a horizontal diagram of the principle of the present invention. 1 shows a data processing fl device according to the invention;

In FIG. 1, 61 is a processing device, 2 is a display device, 3 is an external storage device, and 4 is a data processing unit 5 is a display control unit. 6 is a data reading section. The processing device 1 consists of a central processing unit (CPU) and a memory. Create and process data. Controls the display device 2 for displaying data. Controls the external storage device 3 for data storage and reading (reading). The display device 2 is for displaying data. For example, data stored in the external storage device 3 and data processed by the data processing unit 4 are displayed. The external storage device 3 stores data created by the processing device 1 or other data processing devices. This data is. It is in a predetermined format suitable for storage in the external storage device 3, etc. The display control unit 5 controls the data display device 2.
The display is performed. It also accepts instructions regarding data display. This instruction is. For example, it may be given by the user's manual input from a keyboard (not shown). Or. It is given in the form of a command. The data reading unit 6 includes the external storage device 3
Read data from. Send to data processing section 4. The data processing unit 4 processes this read data according to the instructions received by the display control unit 5 to create data for display, and displays this data! 11111
Send to Section 5. [Operation] In accordance with the instruction received by the display control unit 5, the data processing unit 4 omits 1 (deletes) a portion of the read data other than the portion (display portion) specified by the instruction.
By doing this, the size of the read data is compressed. The data processing section 4 also has a. Regarding the above specified part. Convert the predetermined format as described above to 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 data. Through the above steps, data for display is created. The data for this display is. For example, if you specify that the left and right ends of data to be displayed on the same line are specified as the display range, it will be assumed that only the left and right ends will be displayed, and the middle part will be omitted. ．． ．． Data for such display is stored in the display control unit 5.
When displayed on the display device 2, the leftmost part is first displayed at the left end of the line, followed by the rightmost part. That is. The part between the left and right ends is omitted. When this part is displayed on the screen, it will be blank (
There are no words that are blank). By compressing data by omitting parts other than those specified by the instructions. Parts determined by instructions can be displayed at the same time. [Embodiment] (Explanation of al1 embodiment) Figure 2 is an explanatory diagram of the embodiment and shows a data processing device. In Figure 2, 7 is a screen memory, 8 is a keyboard, 4 is a

It is a part of the memory of the processing device 1, and includes a primary H product area for data, a single product area for processed data, an accumulation area for non-display force data, and an accumulation area for screen display format data.

These areas are used to create data for display.
Used by data processing section 4. The data read from the external storage device 3 is stored in the primary data storage area.

Data for display is stored in the screen display format data storage area, and is referenced by the screen display section 52 for display on the display device 2. Keyboard 8 is. This is shown as an example of an input device, and is used as a terminal when attached to the display device 2. In this example. Use the input Vt position on the keyboard 8, etc. The user manually inputs the information that defines the display range (necessary part of the data) while referring to the data displayed on one page. Therefore, this information is the same as the data displayed on the same line. In column units. This is information that distinguishes between the displayed part (display column) and the non-displayed part (hidden column). From this, the above information is. It can also be given directly by specifying a hidden column (see other examples). Shikashi. Even in such a case, since there is no difference between display processing and distinguishing between display and non-display data, it can be said that display columns are indirectly defined. Therefore,
In this specification, 2. Even when the above information is given in a form that specifies a part that is not displayed, the "displayed part" is defined as "the part determined by the above information (instructions regarding data display)". We will refer to the ``parts that are not displayed'' as ``the parts other than those determined by the above information.'' The analysis unit 41? Regarding the JI number data. Information on hidden columns is created into a table from the information that defines the display range, and is stored in the storage area for hidden column data in the screen memory 7. That is. ? 3 [For a number (multiple rows) of data, the hidden columns are represented by rows and columns (digits). The BNDS creation unit 42 creates display rows (BND
Create data for displaying S) on display device 2. This data is. The data is in a format that can be displayed on the display device 2 and is stored in the screen display format data storage area of the screen memory 7. This data is. It is displayed on the display device 2 together with the display columns. Due to this. It is possible to perform t1 confirmation of information that defines the display range.

Transfer control to the appropriate process. For example, it accepts information that defines the display range and performs the necessary controls for data processing. The screen display unit 52 displays data for display accumulated in the screen display format data accumulation area of the iI screen memory 7. Display on display device 2. Third
The figure shows the data before processing. The external storage device 3 is . For example, D A S D (D
lrsct Access Storage Device
Consists of e). In the external storage device 3. Data is stored in record units. One record is information that should be displayed on the same line when displayed on display Vt position 2. Below, one record will be explained as one piece of data. In Figure 3, r~...1...A...~
” Like. The number of columns is illustrated to show the size of one piece of data. The illustrations from the 3rd column to the 89th column are omitted. In this case, the size of one piece of data is 103 columns, which is larger than the size of one line of the display device 2, which is 80 columns. Note that this number of columns is not stored in the external storage device W3 together with the data.

Such data is expressed in a predetermined format, such as ASCII code, and remains in this format until it is converted by the converter 44. FIG. 4 is a data display processing flow, and FIG. 5 is a diagram showing an example of data display.

■Terminal processing reception section 5! but. Accepts processing input from the user via the keyboard 8 of the terminal. ■When it is necessary to read data for the relevant processing, that is, when data stored in the external storage device 3 is used. The display control section 5 notifies the data reading section 6 of this fact. ■The data reading unit 6 reads necessary (specified) data from the external storage device 3. The data is stored in the primary M product area of the N-plane memory 7 and the processing data storage area. If there is no need to read data, that is, if new data is created by the user, the above processing is not performed. The read or manipulated data is displayed on the display device 2.
is displayed. That is, the converter 44 converts the data into a format that can be displayed on the display device 2. The screen display section 52 displays this on the display device 2. This display is. For example, it will look like Figure 3 (Record 1: etc. will not be displayed). In this case, the entire 108 column data cannot be displayed simultaneously on the display device 2 where one row has 80 columns. ■Now, the leftmost part of one piece of data rsHOUH IN''
and the rightmost part rUR I AGE I and rRIEKI
It is necessary to refer to J at the same time, and the user inputs this information. That is, the #l end processing receiving unit 51 receives a request from the user for display processing from the keyboard 8 of the terminal, in other words, information defining the display range. This means that a request has been made to hide a column of part of the data. The information that defines the display range is. As shown in the second and sixth lines of FIG. 5, input is made by positioning a predetermined pair of marks "<...>" in the range (column) to be displayed. This input requires horizontal scrolling of the screen. This scrolling function is provided in the display control section 5. ■If the above request is made. The analysis section 4l. A notification is received from the terminal processing reception unit 5l. Analyze the request and create a table related to the hidden power column in the M product area of the hidden column data of screen memo I77. At this time, as shown in Figure 5, if the display range shown in the second line is specified for the data in the third line, this specification will extend to the line immediately before the next display range specification (line 6). It is considered to be valid and to define its display range. Therefore, the specification on the second line specifies the display range for the third to fifth lines. The 6th line specifies the display range from the 7th line onwards (up to the last line). By performing such an analysis by the analysis section 4l.
This makes it easier to input information that defines the display range. If the above request is not made. No further processing is performed. ■When the above request is made, that is, when there is a hidden column, the BNDS creation unit 42 and data compression unit 43
This is known from the notification from the i-unprocessed reception unit 5l, and the following processes ① and ② are performed. If there are no hidden columns, the following processes ■ and ■ will not be performed. ■The BNDS creation unit 42 stores the data for displaying rBNDS<...><...> in the screen memory 7 in the screen display format data as shown in the second and sixth lines of FIG. Create it in the specified area of the area. This process is performed based on the notification from the terminal processing reception unit 5l. Or, i! surface memory 7
This is done by referring to the hidden force ram data storage area. ■The data compression unit 43 compresses the data in the primary data storage area of the screen memory 7 based on the table regarding hidden columns. It is stored in the processing data storage area of the screen memory 7. Since the data in the primary storage area of the screen memory 7 is left as is, it is possible to respond to changes in the information defining the display range without performing processing ① or ②. (2) The conversion unit 44 converts the data after pressure tm into a displayable format, and creates data for display in a predetermined area of the screen display format data storage area of the II screen memory 7. At this time, a table regarding hidden columns is referenced to confirm hidden columns.

[Phase] The screen display unit 52 displays data for 5 displays on the display device 2. The result of this display is. The result will be as shown in FIG. In Fig. 5, 21 is a screen,
``Lth line'', ``column position'', etc. are not displayed on the screen. As is clear from the comparison with Figure 3. In Figure 5,
In the 3rd to 5th lines, the 11th to 89th columns of the data in Figure 3 are omitted, and in the 7th to 9th lines, the 33rd to 89th columns of the data in Figure 3 are omitted. It has been done. These columns are based on the information that defines the display range of the second and sixth lines. This is a hidden column. In addition. The display of the read data etc. in the process ■ is also
Process the data in the processed data storage area of the I-side memory 7■
This is done by processing in the same way as and 0. Therefore, reading or editing of data is performed on both the primary data storage area and the processed data storage area of the screen memory 7. (bl Explanation of other embodiments Figure 6 is an explanatory diagram of another embodiment. This embodiment is an example in which information defining the display range is given as a command. Non-display columns are known in advance. In this case, the display range can be specified using a command.In other words, a command to instruct non-display (B N D S) and an operand indicating a non-display column are input on the command line.In this operand, the 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 data are given. is set as a hidden column.As a result, the display shown in Figure 6 is obtained.In this case as well, the predetermined mark "<...>" obtained by converting the command BNDS and the operand is displayed along with the data. It is also possible to obtain a display as shown in Fig. 5 by specifying the number of valid data of the command using the operand. Various modifications are possible according to the main idea.
