Abstract

PURPOSE:To standardize and convert into parts a software by decomposing and defining a data format as a type of a sentence, directly editing a fixed part of the editing data by the type of the sentence and editing by a variable program. CONSTITUTION:An application program 1 sets a code of a bit of information displayed on a CRT5 in a table, activates a CRT editing program 2, converts to the JIS data from the code set by the application program 1 and the display control data is extracted from a sentence type table and added. A CRT communication program 3 converts the display control data into a code sequence proper to the device. In a sentence type entry table, the existence of the type of the sentence is registered in a sequence of the number of the type of the sentence and from the number of the type of the sentence, the sentence type table can be immediately referred. The sentence type table is an aggregate of the display control data to the display information. In order to divide a display screen into the sentence types, the division may be performed for a line or a column unit or a combination of other optional display information. Thereby, the data format processing can be unitedly performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data format designation method in a system that outputs data in various formats to a ledger or screen.

[Conventional technology]

Conventionally, in the data format specification method, each output program handles the data format and edits and processes the data, and the method of processing is also fixed as a constant in the program. There were many cases where the methods of handling were inconsistent.

[Problem that the invention seeks to solve]

In the conventional processing method described above, (1) changes in data format require modification of individual programs; (2) when replacing with another device of the same type with a different interface, the data format may also change. (3) Because data formats are not centrally managed,
There were problems such as the inability to share data even if the format was the same, and (4) the logical separation of program processing functions was inconsistent, making it impossible to promote software standardization and componentization. .

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention (1) decomposes and defines the data format as sentence patterns; (2) divides the editing data into a fixed part and a variable part; (3) The program is divided into a program that processes device-specific data formats and a program that processes logical data formats. It is characterized by doing.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram showing program processing for CRT data format editing in one embodiment of the present invention. The application program 1 sets the code of information to be displayed on the ORT 5 in a table, and starts the CR7 editing program 2. The CRTfi collection program 2 converts the code set by the application program 1 into JIS data, extracts 1 display control data (display color, display coordinates, blink control, ruled line display, etc.) from the sentence pattern table, and adds it. The CR7 communication program 3 converts display control data into device-specific code sequences.

FIG. 2 is a related diagram of tables necessary for editing the data format of FIG. 1.

The screen entry table is a table that shows the location of the screen sentence pattern table that corresponds to the display screen number.The 0 screen sentence pattern table shows what kind of sentence patterns the screen is made up of.The 0 sentence pattern entry table is a table that shows the location of the screen sentence pattern table that corresponds to the display screen number. The location of sentence patterns is registered in numerical order, and you can immediately refer to the sentence pattern table from the sentence pattern number.0 The sentence pattern table is a collection of display control data for display information.0 To divide the screen into sentence patterns, divide the screen by row or column. It is also good as
The 0 edit data code type table, which may be a combination of any other display information, is a table that classifies display information into code types, and is a 0 edit data code attribute table in which the locations of the edit data code attribute tables are registered in the order of the edit data codes. is the edited data (J that can actually be displayed on the CRT)
The 0 edit data code table is the information displayed on the CRT, in which the number of registrations (data written in IS code), attributes such as display size, half-width/full-width, numeric/character data, and location of edited data are registered. It is a collection of clothing items classified into clothing according to the editing data code type.

〔Effect of the invention〕

As explained above, the present invention defines a data format by encoding it as a sentence pattern in a table or file, and when outputting information, edits the data format of a ledger or screen based on the definition of the sentence pattern. (1) Data format processing can be processed in a unified manner. (2) Device-specific processing can be localized, making it possible to become even more independent from the device.

(3) When modifying the data format, the logical separation is clear, and there is an effect that it is only necessary to modify the edited/processed data without modifying the program.

[Brief explanation of drawings]

FIG. 1 is a diagram showing the process in which a CRT data format is edited by each program according to the present invention, and FIG. 2 is a diagram showing the relationships among tables necessary for editing as shown in FIG. l: Application program. 2: CR7 editing program, 3: CR7 communication program, 4: Line protocol handler. 5: CRT,

Claims (1)

[Claims] In printing and display systems such as computers, printers, and CRT devices, the data format on a ledger or screen is encoded and defined as a sentence pattern in a table or file, and the sentence pattern definition is used when outputting information. A data format specification method for output information that edits the data format of the ledger or screen.
