Abstract

PURPOSE:To attain automatically the screen addressing at each digit at the multistage display, by providing a multistage mode discrimination function and a screen address control function for said mode to a display controlling device. CONSTITUTION:Various address registers for multistage display control are assigned to an RAM in a controller performing a CRT display control and a keyboard input control. A register TZAA consists of address registers 201AS, 201AE, 201BS, and 201BE storing each row address of the upper end row and the lower end row of a paper-tablet shaped areas A, B on a display screen. A register TZBA consists of registers 202S and 202E storing the addresses of the upper end row and the lower end row of an area in which the write is done at present. A register TZCA stores the next write location in the row represented with a register in the TZBA. The screen addressing at each digit is executed automatically with those registers.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display control device suitable for use in a Japanese world processor having a multi-column editing function.

[Technical background of the invention and its problems]

In recent years, a ``multi-column'' II collection function has been added to one of the document collection functions of Japanese world processors. This is a method in which the two-dimensional space on the CRT display screen or printing paper is divided into multiple stages, and the character strings of the document are folded and printed within the divided areas as shown in Figure 1. In addition, calibration is also performed within this divided space. When editing this multi-column set, C
RT The display screen is rarely used from the left corner to the right corner, and depending on the configuration of one column, the character string of the document is displayed within a narrow digit range from the top line to the bottom line. Displayed again.

When displaying characters on a CRT screen using the multi-column display function described above, there is no problem with display control if the finger is added to the address control device each time at one character position. After adding the display address to , the character string is transferred.19 In the case of a control method that automatically increments the address on the control device side, at the beginning of each digit of the multi-column display, The problem is that the screen address must be added each time, and therefore, when multi-column display is performed using address control using the conventional control method, the display rewriting speed decreases and the load on the host device increases. occurs.

[Purpose of the invention]

The present invention was developed in view of the above circumstances, and it is possible to automatically specify a screen address for each digit during multi-column display, thereby reducing the load on the host device.
Furthermore, it is an object of the present invention to provide a display control device 1 capable of improving the - side display rewriting speed.

Ding [Summary of the Invention] The present invention provides a multi-column mode function and a screen address control function for the multi-column mode in a display control device.
When the above-mentioned multi-column mode is set, the top and bottom line positions of 1 column are added, and the data is sent sequentially after the first screen address is specified. This is configured so that the second screen address is incremented for the character code string, and when it exceeds the bottom line position, the next screen address is automatically set to the top line position of the next digit.
This makes it possible to omit the screen address for each digit from the host device, thereby reducing the load on the host device and improving the screen display rewriting speed.

Here, the operation in one embodiment will be explained with reference to FIGS. 1 to 4. When the multi-stage light display mode cross key FKx provided on the key-code input device 1ar is operated,
The key information associated with this key operation is the CRT/KB controller 105° and system path (C-BU8).
is sent to CPUJ## via. CPU J00
When it receives this key manual information, it sends a friend's foot guide message information 111 to the CRT/1 (B controller 1011) instructing the operator to input information on the top and bottom O row positions of each row. When the CRTAB controller 105 receives this guide message and message information, the CRT AB controller 105
eat control and output the guide meeting information on the CRT display screen. Following the guide message and message on the CRT surface, the operator presses the key on the input device 1.
When each line position information va' is input using the cursor movement key and data input key on 07, the input line position information is sent to CPU J 00 and taken into the CPU. At this time, if there are columns of products, the row position information of the top and bottom ends of each column is manually inputted successively. CPU J 00 is the line position information according to the above key manual @
[When received, it sends a % command to the CRT/Kl controller 1ott and displays the position information of each line that has just been imported.
l The data is transferred to be set in the work area of the required memory in the CRT/KB controller 105. The CRTAB controller 105 interprets the commands from the CPU J o and reads the TZAA shown in FIG.
Register (201, :101, 101B1.2
Set to 01B (01B). At this time, for example, if only the row position information of the top and bottom ends of one strip-shaped area A is input, the row position information of the top end of that area is set in the address register section j OJ A, and the row position information of the bottom end is input. The information is set in the address register section 2o1, and the remaining address register section 201B.

j　O1Bg are all in the clear state.

Also, when the row position information of the upper and lower ends of the two strip-shaped areas A and H is input, the row position information of the upper end of the area A is stored in the address register section J01A, and the lower end of the area A is input. The row position information of the upper end of the area B is stored in the address register 20 J Al, and the row position information of the upper end of the area B is stored in the address register @
20 JB.

Then, the row position information of the lower end of the area B is set in the address register section 101B.

CPU J #0 then issues a command to the CRT/k II core controller 105 to enter the multi-column display mode, and thereafter transfers the top screen address and the character code string to be displayed. When the CRT/KB controller 1-5 receives the above command, it sets a control flag indicating the multi-column display mode and starts display control operation in the multi-column display mode according to the processing procedure shown in FIG. First, in which strip-shaped area does the digit position information of the first screen address that has been transferred be included? (201, 101, 201B,

Check whether it has been exceeded or not. Here, the contents of the LA section are T

If this kind of operation is repeated, the CPU
The character code string continuously transferred from the CRT/i (B controller 105 controls the address and is continuously written in the strip-shaped areas (A, B) as shown in Fig. 1. It will be inserted and output.

Since the multi-column display control is performed as described above, each time the digits of the multi-column display are updated, the CPU JO# returns ii! There is no need to transfer 1TkJ address,
Therefore, the load on the CPU J00 is reduced, and
Display rewriting processing speed can be improved.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to automatically specify the screen address for each digit during multi-column display, thereby reducing the load on the host device and It is possible to provide a display control device that can provide display information at JltA speed.
