Abstract

PURPOSE:To facilitate output processing by providing a storage part for information for controlling the output of fixed display characters displayed at a specific position in a character screen frame and a storage part for information for control based upon the output of variable display characters. CONSTITUTION:The default area control information which controls the output of fixed display characters displayed at the specific position in the character screen frame is stored in the storage part 9a and the input area control information which controls the output of variable display characters at the specific position in the screen is stored in the storage part 9b. Then a selector 6a reads information out of either of the storage parts 9a and 9b and a control part 5a displays characters on a screen display means 4a according to the information.

Description

[Detailed Description of the Invention] [Summary] A storage unit for default area control information that has a screen display means using a character screen and controls the output of fixed display characters displayed at a predetermined position within the screen frame; a storage section for input area control information that controls the output of variable display characters at a predetermined position; means for selecting the two storage sections; and control information based on one of the two storage sections selected by the selection means. and a control unit that controls display processing.

[Industrial application field]

The present invention relates to a method for outputting characters to a character display.

[Conventional technology]

Generally, when creating forms using a character display 1. The processing task for creating the form operates, and among the characters written on the form, fixed characters that are written in a fixed format are written by the processing task, and characters that change each time are written from the keyboard.

FIG. 3 (al is a block diagram of conventional character output control.

FIG. 3 (bl is an explanatory diagram of the display screen.

In the figure, l is a display screen, 2I to 2. , is an input field, 3 is a default field, 4 is a screen control section,
5 is a task operation area, 50 is a processing task area, 51 is a display task area, 6 is a processing control unit, 7 is an instruction means, 8 is a task storage unit, 80 is a processing task, 8a is a default data display control task, 8b 8c is a display control task for input field data, and 8c is a font attribute table. □The same symbols represent the same objects throughout the figures below.

If you are currently using character display screen 1 with a screen size of 24 lines and 80 columns, there will be 24 x 80 locations (
It is possible to write characters in 1920 locations), of which characters are written from the action task in a defined area, and characters are written in other areas from the keyboard.

Note that the area where characters can be written from the action task is the default field 3, and the area where characters can be written from the keyboard is the input field 2. It is said to be ~2° (indicated by diagonal lines).

In the conventional system, as shown in FIG.
issues an interrupt signal to the task storage section 8, loads the processing task 80 into the processing task area 50 in the task operation area 5, and transfers execution rights.

In this way, when the processing task 80 starts processing and reaches an execution step within the task that requires screen control, ■ If display control is to be performed in the default area, a startup interrupt is issued to the display control task 8a, and the display task It is loaded into the area 51 and the execution right is transferred.

(2) When performing display control on an input field, an activation interrupt is applied to the display control task 8b, the task is loaded into the display task area 51, and the execution right is transferred.

0 As mentioned above, in the conventional method, each task 8 has a work area within the task, and the configuration is such that assembling character types to be displayed and assigning attributes to each separate display position is performed in two steps. .

[Problem that the invention seeks to solve]

However, when outputting characters to the display screen 1, it is generally necessary to specify the font, color, brightness, whether flicker is required, etc., in addition to the screen position and displayed characters. For this reason, conventionally, a font attribute table 8c is provided, and the font, color, brightness, need for flicker, etc. to be adopted are determined by referring to the font attribute table 8c before outputting, which complicates the processing at the time of output. There was a problem with this.

[Means for solving problems]

The above problem, as shown in the principle diagram of FIG. 1, includes a screen display means 4a using a character screen, and default area control information that controls the output of fixed display characters displayed at a predetermined position within the screen frame. a storage section 9a, a storage section 9b for input area control information that controls the output of variable display characters at a predetermined position within the screen, means 6a for selecting the two storage sections 9a and 9b, and selection by the selection means 6a. This can be solved by including a control section 5a that controls display processing based on control information of either of the two storage sections 9a and 9b.

[Effect]

According to the present invention, the control unit 5a that executes the display process retrieves the default area control information or the input area control information from the two storage units 9a and 9b by the selection unit 6a, and based on the agitation, the screen display unit 4a selects the character, Display text on the lid screen.

〔Example〕

FIG. 2 (al is a block diagram of one embodiment of the present invention.

FIG. 2 (bl is an explanatory diagram illustrating a display character control table of the present invention.

In the figure, 51a is a display task area, 52 is a table area,
60 is a processing control unit, 81 is a data display task, 90 is a table storage unit, 91 is a default SR area control table,
92 is an input area control table.

When the activation signal is input to the processing control unit 60 from the instruction means 7, the processing control unit 60 notifies the task storage unit 8 by an interrupt signal, takes out the processing task 80, and stores the processing task prepared in the task operation area 5. It is loaded into area 5o and given execution rights.

When the processing task 80 starts processing and reaches an execution step within the task that requires screen control, it notifies the processing control unit 60 and requests activation of the data display task 81.

The processing control unit 60 takes out the data display task 81 from the task storage unit 8, loads it into the display task area 51a prepared in the task operation area 5, and then hands over the execution right.

After the data display task 81 executes a predetermined initial step, (1) it notifies the processing control unit 60 to successively output the default area control table 91 from the table storage unit 90 (the selector 6a refers to the above processing), and the task It is written in the table area 52 prepared in the operation area 5, and one character is created on the display task area 51a with reference to the default area control table 91 (the display processing means execution control unit 5a refers to the above process). .

That is, the specified screen display position P is, for example,
If the column is iii-iv, the screen control unit 4 sets the default eM area character type as “A B C-iii”.
The display character attribute 1d is displayed in green, large letters, and Roman numerals.

The screen control section 4 outputs the characters created on the display task area 51a on the screen (the screen display means 4a refers to the screen control section 4).

(2) Notify the processing control unit 60 to read the input area control table 92 from the table storage unit 90, write it to the table area 52 prepared in the task operation area 5, and display it with reference to the input area control table 92. Task area 51a
Create text on top. That is, if the specified screen display position is, for example, the second field, the input area character type (
(Number) M indicates alphanumeric characters (8 characters), and display character attribute If displays characters input from the keyboard in green/Bowman font.

The screen control unit 4 outputs the characters created on the display task area 51a onto the screen.

〔Effect of the invention〕

As described above in detail, the present invention has the great effect of simplifying the processing to be performed when outputting data, thereby enabling efficient output processing.
