Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a common control method for output display sentences in a data processing system, which automatically selects and creates output display sentences such as Japanese or English characters based on the display type of a display terminal.

Traditionally, when designing a screen processing application (business program), when trying to display output such as labels or messages in Japanese, the difference between Japanese and non-Japanese text depends on whether the display terminal device used can display Japanese. It was often necessary to make sure that the display screen could be used for both the language and text. There was also a similar problem with the output of error messages.

The present invention enables an application (business program) to be designed completely independently of the display type of such a display terminal device.
The output display sentence processing is separated from the application and integrated into a common control unit, and by identifying the display type of the display terminal during program execution, the screen is automatically selected to display Japanese text or non-Japanese text, It is designed to enable appropriate output display, and as a configuration for this purpose, the application control unit is used in data processing systems that are connected to display terminals with different display types, one for displaying kanji and one for displaying alphanumeric characters. and an application processing unit, and the application control unit receives processing request information and terminal display type information from any display terminal, analyzes the processing request information, and adapts a business program necessary for processing. The application processing section then instructs the processing result using a display content code and returns control to the application control section, and the application control section transmits the processing result to the processing. When the request is sent back to the display terminal, the display screen is created by selecting either a Japanese text or an English text based on the terminal display type information, display content code, etc. It is something.

FIG. 1 is a conceptual explanatory diagram of the present invention. In the figure, 1 is a screen buffer that communicates between the display terminal and the data processing device. 2 is an application control unit, which has the function of centrally controlling all processing requests from each display terminal;
In particular, the present invention includes a function to select and control the output display sentence format. Reference numeral 3 denotes an application, ie, a business program, that corresponds to the processing requests of the display terminal. 4 is an example of a Japanese text display screen sent to a Kanji display terminal, and 5 is an example of an English text display screen with the same content sent to an alphanumeric display terminal.

When the application control unit 2 receives a processing request from a terminal, it selects an application necessary for the processing and executes the processing. Application 3 performs editing processing on the screen buffer 1 to finally compose the processing results on the screen.
A display text such as a label or a message is not created, but only a display content code and a screen display position are instructed, and control is passed to the application control section 2.

The application control unit 2 identifies the display type of the display terminal that received the processing request, that is, whether it is a kanji display or a non-kanji (alphanumeric) display, and prepares a display content code in advance according to the type. The dictionary table is looked up, converted into final character screens as shown in screens 4 and 5, and sent to the requesting terminal.

FIG. 2 is a block diagram of a data processing device implementing the method of the present invention.

In the figure, 6 is a central processing unit, 7 is a storage device, 8 is a transmission control device, 9 is a kanji display terminal for displaying Japanese sentences, and 10 is an alphanumeric display terminal for displaying alphabetic characters. Further, the central processing unit 6 is provided with an application processing unit 11 and an application control unit 12, and the storage device 7 includes a message reference block for managing processing requests from each terminal. MRB13
, an output display text table 14 for Japanese and English texts, and a screen buffer 15 that functions both as an input/output buffer and as a working memory.

Processing request information from the display terminals 9 and 10 is stored in the screen buffer 15 via the transmission control device 8. The processing request information consists of an input message, a control word, a terminal display type, a line address, etc. The application control unit 12 sets the MRB 13 for each piece of processing request information. MRB
In addition to processing request information, the area includes an area for saving when an interrupt occurs, an area for working, and the like.

Processing requests from display terminals 9 and 10 are processed screen by screen. Once the MRB is set for each request, message analysis is performed for it.
Business program modules necessary for processing are organized for each screen content to be processed, and a queue is formed for the application processing section 11. The application processing unit 11 has a large number of modular business programs, and sequentially executes processing based on a queue of processing requests.

When the application processing unit receives instructions from the application control unit and completes all business program processing for one screen, the application control unit 12 determines the display type of the terminal previously stored in the MRB 13. Table 14 of Japanese and English sentences, depending on whether they are kanji or non-kanji (alphanumeric characters)
, the data in the screen buffer 15 is replaced with either Japanese text or English text. The screen information that is subject to this display sentence selection control is distinguished by a flag for each screen data, but it is also possible to distinguish it by screen area information, such as a Japanese text area and an alphanumeric text area. good.

Completed output screens are queued and sent to their corresponding display terminals.

The present invention has been described in detail above, but according to the method of the present invention, when designing an application, it is only necessary to consider the processing and reference of screen data, without having to be aware of the details of the output display format. This makes it much easier to manage the system, making it easier to manage the system and increasing efficiency.

Claims (1)

[Scope of Claims] 1. A data processing system to which display terminals of different display types, one for displaying kanji characters and one for displaying alphanumeric characters, is connected, comprising an application control section and an application processing section, the application control section receives terminal display type information along with processing request information from an arbitrary display terminal, analyzes the processing request information, matches a business program necessary for processing, and causes the application processing unit to execute the processing; The processing unit instructs the processing result using a display content code and returns control to the application control unit, and when the application control unit returns the processing result to the display terminal from which the processing request was made, the terminal display An output display text common control method characterized in that a display text of either a Japanese text or an English text is selected based on type information, a display content code, etc., and a text screen is created.
