Abstract

PURPOSE:To easily insert a page by finding out the number of liens based on the page length and line base and inputting required codes corresponding to the number of liens in a storing means. CONSTITUTION:A length value corresponding to one page set up in a page length control register T-P-LEN and the values of line bases set up in respective page line space control registers P-LSPs corresponding to a cursor existing page control register C-PAGE from the C-PAGE are fetched from a display control register group DCR 8. The value set up by the T-P-LEN is divided by the line base value to calculates the number of liens to be set. Since the codes corresponding to the calculated number of lines are set up in the page positions corresponding to the original bases, the corresponding number of codes can be set up in the addresses of a P-STA-2-1. Thus, codes can be set up in a buffer memory DB7 only by the necessary number of codes.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an information processing device, and particularly to an information processing device that creates and edits sentences and tables.

[Prior Art] A word processor is a typical processing device that handles text information. Create sentences with a word processor, WA
When collecting data, processing is performed in units of pages. In a device that uses pages as a unit, processes such as creating a new page or deleting a page can be easily performed.

[Problems to be Solved by the Invention] However, devices that use pages as units have drawbacks such as the inability to easily perform editing that spans multiple pages. In order to solve these problems, a device that does not separate text data into pages, but treats it as continuous data, and displays page distinctions when editing on a display device, etc. is considered. , currently widely used. These devices that handle data as continuous data have a drawback in that they cannot easily perform IJit collection on a page-by-page basis, which could be easily done with devices that edit on a page-by-page basis.

Furthermore, when creating a new page, conventional methods have had the disadvantage of using a large amount of data and requiring a large amount of space such as a data area. Furthermore, by changing the line pitch,
When the number of lines in one page changes, the operator must calculate the corresponding number of lines and create a new page, which has the disadvantage of placing a large burden on the operator. Ta.

The present invention has been made in view of the above-mentioned shortcomings of the prior art, and its purpose is to treat text data as continuous data and to provide information that can be inserted or deleted page by page. The purpose of this invention is to provide a processing device. Also,
Another object of the present invention is to provide an information processing device that can effectively utilize data during page insertion processing.

Furthermore, another object of the present invention is to automatically determine the number of page lines in accordance with factors determining the number of page lines, such as page length and two-line pitch, during page insertion processing, thereby reducing the burden of editing on the operator. An object of the present invention is to provide an information processing device that can perform processing more easily.

[Means for Solving the Problems] The present invention provides a storage means for storing sentences, and a storage means in which the number of sentences is small (tt<kb1). The present invention is characterized in that it comprises a page insertion means for inserting a page into the storage means by a predetermined number of input operations.

] represents the starting position and DB[315] represents the final position, forming a continuous buffer memory.

FIG. 4 is a diagram showing a detailed configuration example of the display control register group 8 shown in FIG.
LEN) is a register that holds the length of each page as a value, and for example, 1712 inches is expressed in units of 1.
(12=1 inch). For example, if paper with a length of 10 inches is used as the standard, this page length control register (r-p-uNt
is set to a value of 120. Further, this value can be set using the numeric keys on a keyboard as a general processing means. In the embodiment using the flowchart below, it is assumed that a value of 14 is set as the default value.

Each page line space control register (PLSP[0
] ~P-LSP [nl) sets the line space (distance between lines) of each page in the page length control register (
Similar to TP-LEN), it has a length value in units of 1712 inches. Generally, one line space is 176 inches, and the value is 176 inches = 2.

In this embodiment, 1 line space and 2 line spaces are used, and values such as 2 for 1 line space and 4 for 2 line spaces are registered in each page line space control register group. It is assumed that registration is automatically set in this register group by executing display as part of the display function. These values represent the line space values at the beginning of each page, and it is also possible to change the line space in the middle of each page.

Each page start address control register group (P-5TA[0
]~P-5TA [nl) has the value of the start buffer position and data buffer of each page, and indicates the start buffer address of each page. By referring to this register group, it is possible to know the starting buffer position of each page. Also, like each page line space control register group, these page head address control register groups are set and changed each time display is executed as part of display processing.

The cursor existing page control register C-PAGE is a register that holds the number of pages where the cursor currently exists, and similarly, the number of pages where the cursor currently exists is held as a value in accordance with display processing. It is assumed that the information is updated at any time by the cursor movement 9 indication process.

Referring to each set in the various registers explained above,
The page insertion and deletion processing described below is executed.

FIG. 5 shows an example of how sentences input from the keyboard 4 are displayed on the screen of the display device 9. This is a format line showing the format on the screen of the FML display device 9, and displays margin positions and tab positions.

II L” displayed on the format line FML is the left margin position, “R” is the right margin position, °
゛t" indicates a tab position, and °°." indicates a character input position. In this embodiment, 18 lines in addition to the farm line FML serve as a display area for displaying text. The cursor CR is displayed on the screen like "°". Note that "°" is EOF.
A special code indicating (endof file),
Indicates the final input position of the input string. Note that in an actual device, this part may not be visible. When the cursor exists at this EOF position, when a new character is input to the buffer memory 7 position of this EOF, the EOF moves one position backward in the buffer memory 7.

The lines expressed as “<+−−−−−−1” represent page changes, and in this Figure 5, one page is represented by pages 1, 2, and 3, each consisting of 7 lines. The pages are distinguished by a page change symbol.This page change line does not exist as data in the buffer memory 7 and is displayed on the screen according to the page length and line space conditions. "Th" is a special code that indicates indentation and indicates left alignment.

FIG. 6 shows an example after pressing the special key PAGE INS on the keyboard 4 to execute the page insertion process in the example shown in FIG.

In Figure 5, page insertion processing is performed on page 2 where the cursor CR is located, and in Figure 6, the text on page 2 is moved to page 3, and a new page consisting of a carriage return is added to page 2. This shows how page 2 has been created.

FIG. 7 is a diagram showing the screen after executing the page deletion process by pressing the special key PAGE DEL on the keyboard 4 for page 2 where the cursor CR of FIG. 5 exists. FIG. 7 shows how all of the sentences that existed on page 2 in FIG. 5 have been deleted, and the subsequent sentences have been compressed (moved up) and displayed.

FIG. 8 is a diagram showing an example of a special case of page insertion, and shows a change in line space at the end of page 1 [L2
] is entered. Normally, the default line spacing is line spacing 1 (176 inches between lines), but if you change the line spacing in the middle of a sentence by changing the line spacing, you can [ It is assumed that settings can be made to indicate a two-line space as shown in [L2].

Regarding changing the line space, there is a key corresponding to this in the special key group of the keyboard 4, and by pressing that key and using the corresponding number key, one line space can be changed anywhere to concentrate on MA. shall be. FIG. 8 is an example in which the line space is changed to 2 at the end of page 1, and is a diagram showing the screen display after page insertion processing is performed on page 2. .

In Figure 6, the newly created page 2 is made up of one page with seven carriage returns.
In FIG. 8, three carriage returns constitute one page.

FIG. 9 shows the contents of the buffer memory 7 when the display shown in FIG. 5 is performed, and similarly, FIG. 10 is shown in FIG. 6, FIG. 9 is a diagram showing the contents of the buffer memory 7 for each display screen in FIG. 8. FIG. The character string displayed as shown in the figure is continuously stored in the buffer memory 7, and
There are special codes ``CR'', ``i'', ``
c', "eof", and "n" are included. "C.
R” is a special code indicating a carriage return,
The character string after this code ``'CR'' is displayed from the next line.=Ii'' is a special code that indicates the indentation range in the buffer memory 7, and from IIi'' to °°
The range surrounded by "i" is treated as an indent.+
+C" is a special code that indicates the indent setting column position, and the number of columns is stored as a numeric string within the range surrounded by this "C". Here, a is °C'"1011

Next, an example of the operation of the apparatus of the present invention shown in FIG. 1 will be described in detail with reference to the flowcharts in FIGS. 13 to 16.

FIG. 13 shows the entire processing procedure when one key on the keyboard 4 is pressed, and by repeatedly executing this processing procedure, character processing such as the above-mentioned or other text creation/editing is performed. .

First, in step S1, a key input from the keyboard 4 is waited for, and if it is determined that a certain key has been pressed, key capture processing is executed in the next step S2. In this import process, a key code corresponding to the pressed key is extracted and it is determined in step S3 whether or not the key code corresponds to the general key 81 (shown in the second figure).

When the key code is that of the general key KBI, key set processing is executed in step S4. In this key set process, a key code is set in the buffer memory 7 according to the cursor position set on the display screen.

On the other hand, the key code is B for general keys and special keys other than Bl.
2 (as shown in the second figure), the process advances from step S3 to step S55 to execute special processing corresponding to the key code.

For example, if the input key is the PAGE INS key, which is a special key, page insertion processing is executed.

This detailed explanation will be given using the flowcharts that follow. When the contents of the buffer 1 memory 7 are changed by the above key set processing and special processing, the next step S6
The contents of the sofa memory 7 are displayed on the display device 9 through the screen display process, and the cursor information check process in step S7 is performed. This completes the process for pressing one key and returns to step S1 again to wait for the next key to be input.

Next, the special processing in step S5 in FIG. 14 will be explained in detail.

In this embodiment, descriptions of special processing other than page insertion and deletion will be omitted; however, character insertion and deletion.

Various types of editing are performed. As shown in FIG. 14, first, in step 510, it is checked whether it is the PAGA INS key. If the PAGE INS key is pressed, the process advances to step Sll, where page insertion processing is executed (page insertion processing will be described in detail with reference to FIG. 15).

If a key other than the PAGA rNs key is pressed in step SlO, the process advances to step S12, where the PAGE
Check whether the DEL key is pressed. PAGEDEL
If the key is pressed, the process advances to step S13, where a page deletion process is executed (the page deletion process will be explained in detail using FIG. 16).

The above process creates a special code, PAGE INS key.

The PAGE DEL key and other special key processes are executed and the process returns to the main routine. FIG. 15 is a flowchart illustrating details of the page insertion process described in step Sll above. First, in step SL5, from the value set in the page length control register T-P-LEN and the cursor existence page control register C-PAGE, the CPA
The line space value set in each page line space control register group P-LSP corresponding to GE-1 is taken out. The value set in the page length control register T P LEN is divided by the line space value set in each page line or base control register. As a result, the number of lines to be set is calculated. In the example shown in Figure 5, the page length control register (7 lines in total and calculated with a line space of 1, the total length of the page is 7X2 = 14. The unit of 1 indicates 1/12 inch.) is set to 14, and the cursor existence page register C-
Two pages are set in PAGE, and each page space control register takes out the line space value set in P-LSP[2-11. Since the line space of the second page is 1, P-LSP [2-11
The value is set to 2. The number of lines is 14/2=
It is calculated as 7. From this calculated number of lines, in step S17, seven codes ``'OR'' corresponding to the number of lines calculated in step S18 are set at the page position corresponding to the original page. At the address of P-5TA [2-1] of the address control register group,
Set the corresponding number of codes “°cR”. A commonly used method for setting is to move subsequent buffers by the number of times the buffer is set, and then set the code "CR" at the buffer position created by eight shifts.The required number is set in step S17. The corresponding code ``'OR'' is set in the buffer memory 7. This completes the page insertion process and returns to the main routine. By the display processing of the main routine, the screen after the page insertion processing is executed is displayed as shown in FIG. 6, and the page insertion processing ends.

Also, to explain the case where there is a change in line spacing in the middle of a sentence using the example in Fig. 8, register P-LSP [
2-1] has a line space of 2, so 4 is set as the value. Since the total length is 14, the number of lines is calculated as 14/4·3. From this calculated value 3, three codes "CR" are set in the buffer memory 7 in the same manner as in the example described above.Display is executed in the same manner and is displayed in FIG.

The state of each buffer 7 memory is shown in Figure 1O and Figure 1, respectively.
Shown in Figure 2.

As explained above, according to the present invention, a new page can be created.

Next, the page deletion process in step S13 in FIG. 14 will be explained using FIG. 16.

First, in step S18, the address set in each page start address control register corresponding to the number of pages set in the cursor existing page control register C-PAGE minus 1 is retrieved. The address set here becomes the deletion start address. [: PAGE+1 The address set in each page start address register becomes the address of the final address of deletion +1. These two addresses are taken out, and data between these two addresses is deleted from the buffer memory 7 in step S19.

To explain specifically using the example of FIG. 5, a value of 61 is set at the top address of the page.

This corresponds to the start address of page 2 of the buffer 7 memory 7 in FIG. Furthermore, the value 214 is set in the address of (:PAGE+1). This is the start address of page 3.

In step S19, these two addresses 61 to 214-
The data between 1 and 1 is deleted from the buffer memory 7. This process is a well-known process in which the buffer memory 7
This is executed by moving the data from the address 214 of ``EOF'' to the address 61 of ``EOF''. These page deletion processes in step S13 are completed, and the process returns to the main routine. The display is executed in the main routine,
A message indicating that the page has been deleted is displayed as shown in FIG. FIG. 11 is a diagram showing the inside of the buffer memory 7 corresponding to FIG. 7.

As explained above, l) Even in an information processing apparatus that does not have a buffer structure in units of pages, it is possible to edit and delete pages in units of pages.

2) By setting a carriage return code when creating a new page, you can insert pages using the buffer more effectively.

3) The number of lines is automatically determined based on the page length and line space, making it easier to insert pages.

In this example, the indent special code "i", the indent position special code "Coo", and the line space change special code "1" are used, but codes that can identify these may also be used.

[Effects of the Invention] As explained above, according to the present invention, pages can be inserted extremely easily.
