Abstract

PURPOSE:To facilitate the production/change of the output data by using the output data separated the general character strings from the control character strings for each screen and displaying the data on a screen after coding the data. CONSTITUTION:In a screen control system where the characters are displayed on a screen for execution of the control, a WCC (write control character) byte part 1-0 includes the WCC serving as a command for writing on the screen, an SBA (set buffer address) and a field address. Both the SBA and the field address are used for designation of a buffer address prior to a specific order action. For instance, the head SBA (1, 1) in a control character group 1-2 instruct to store a general character string 1-1, etc., out of the buffer address of the coordinates (1, 1). Here the character group 1-2 also doubles as a character group that points the writing positions of various control jobs and these control contents. Thus the string 1-1 is separated from a series of control character groups 1-2 and coded in the output data 1. Then these string 1-1 and the group 1-2 are displayed in a coding mode.

Description

[Detailed Description of the Invention] [Summary] A screen control method in which characters are displayed on the screen for control. When coding general character strings and control character strings into output data separated by screen, The purpose is to understand the image of the column and easily create and change it, and it is equipped with output data that separates the general character strings to be displayed on the screen and the control character groups that perform various control instructions on a screen-by-screen basis. The general character strings in this output data are displayed in almost the same arrangement on the screen, and control characters are associated with each corresponding position on the screen to write input prohibition/permission, etc., and the instructed control is performed. Configure it as follows.

[Industrial application field]

The present invention relates to a screen control method that displays characters on a screen and performs control.

In recent years, menu screen methods have been used to improve the usability of man-machine ink faces.
In order to display a large amount of information on one screen, the number of control characters has increased, making it difficult to create screen data.

[Prior art and problems to be solved by the invention] Conventionally, output data for displaying data on a screen is processed using WCC (Write Control) as shown in FIG.
rolCharacter) consists of a set of hide, order (2111 characters), and general characters. When displaying general characters on the screen, as shown in Figure 4 (b), the general characters are displayed on the screen in accordance with the display position (display coordinates) specified by the order and whether or not the specified screen input is possible. In addition to displaying the screen, it was also possible to control whether or not the screen could be operated manually.

For this reason, when creating a menu screen by coding a program by looking at output data that includes a mixture of orders and general characters, as shown in Figure 4 (b), it becomes difficult to grasp the image of the entire screen, and There were problems in that it was difficult to change the screen data and it was difficult to change the screen data.

The present invention enables easy creation and modification by grasping the general character string image of the entire screen when coding general character strings and control character strings into output data separated into m screens. The purpose is

[Means to solve problems]

Means for solving the problem will be explained with reference to FIG.

In FIG. 1, output data 1 is W CC (Writ
e Control Character) Hide part 1
-0. -e Consists of character string I-1 and control character group 1-2.

The general character string 1-1 is a character string to be displayed on the screen.

The control character group 1-2 is a character group that instructs various controls such as input prohibition/permission.

Screen 2 is for displaying characters and the like.

The character string display section 3 extracts the general character string 1-1 from the output data 1 and displays it on the screen 2.

The control character writing unit 4 writes the control character group 1-2 of the output data l.
and writes the specified control (input permission/prohibition control, etc.) at the specified position.

[Effect]

As shown in FIG. 1, the present invention includes a general character string 1-1 that is displayed on the screen for each screen in the output data 1, and a series of character strings that are not displayed on the screen but that instruct input permission/prohibition. The control character group 1-2 is coded separately, the character string display section 3 displays the general character string 1-1 on the screen 2 in almost the same manner as it was coded, and the 'llJ character writing section 4
Input prohibition/permission is written at the position immediately before the corresponding general character designated by the coordinates coded by the control character group 1-2.

Therefore, when coding output data 1, you can work while looking at the layout, which is almost the same as if only the -general character string l-1 was displayed on screen 2, and you can grasp the image of the entire screen and easily output it. Creation of data 1 It is now possible to make changes.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be explained in detail using FIGS. 1 to 3.

In FIG. 1, the Wcc hide section 1-o sends a WCC (Write Cont.
roleCharacter), SBA (Se
tBuffer Address) and a field address.

The SBA and field address are used to specify the hardware address prior to a particular order operation. For example, the first " in the control character group N-2 in Figure 2
SBA (1,l) ゞinstructs to store a general character string 1-1 etc. from the hasher address of locator 1 (1,1).

The general character string 1-1 is displayed on the screen 2 as shown in the upper part of Figure 2.
It is a collection of general characters coded exactly as shown above.

The control character group (order sequence group) 1-2, as shown in the lower part of FIG. 2, is a character group that indicates the position where various controls are written and the contents of the control.

Next, the operation of the configuration shown in FIG. 1 will be explained in detail using an example of coding the output data shown in FIG.

In Fig. 2, firstly, -enCC 3BA (1, 1) coded at the beginning of output data 1 writes the following general character string 1-1 etc. from the buffer address (1, 1) and displays screen 2. This is an instruction to display it on top.

Second, the general character string 1- coded from the third line
1 is displayed on the screen as shown in FIG. 3 by the character display section 3 in FIG. 1 at the line and digit position as coded. Therefore, when coding the general character string 1-1 of the output data 1 in Figure 2, the general characters can be coded in the same arrangement as displayed on screen 2, even if they are not displayed on screen 2. If you do this, you can easily create and change the screen while understanding the image of the entire screen.

Third, the control character group 1-2 coded in the lower row is
The control character writing unit 4 shown in FIG. 1 writes the various control instructions in a manner that they are embedded in the corresponding positions.

(For example, "5BA (1, 1), SF,
,1) 'c table"'!". SF, X'EO' is “
"Screen input prohibition instruction"(X'EOma). Therefore, until the "screen input prohibition instruction" is written to the buffer address (1, 1>) and the screen permission instruction "SF, χvC8ma" is written next, Screen input is prohibited.

As described above, -C character string 1-1 and control character group 1-
By separating 2 and coding it into output data 1, you can easily create a menu screen by looking at the coded general character string 1-1 and judge the overall layout.
It is possible to change it.

FIG. 3 shows an example of a display screen in which the output data 1 shown in FIG. 2 is displayed on the screen 2. Here, since the general characters displayed on the display screen have the same arrangement as the general character string 1-1 coded in the output data 1 in Figure 2, there is no need to display them on the screen 2 as a display screen. By looking at the general character string 1-1 coded in the output take 1, the menu screen can be easily created and changed.

On the other hand, if the conventional output data structure shown in Figure 4 (a) is adopted, it is necessary to code as shown in Figure 4 (b) in order to code the same screen as the display screen in Figure 3. It is extremely difficult to predict the entire display screen in the coded state.

〔Effect of the invention〕

As explained above, according to the present invention, output data is provided in which general character strings and control character strings are separated for each screen, and the output data is coded and displayed on the screen. 1, the output data 1 can be easily created and changed while viewing the overall image in the same layout as the general character string 1-1 displayed on the screen 2.
