Abstract

PURPOSE:To perform the conversion of large capacity with a single operation and at the same time to produce an application program having the high maintenance property by building a conversion program into a format converter and performing the control of conversion of the character codes. CONSTITUTION:A format equivalent to one screen is registered to a conversion format 10, and a conversion instruction is read out of the format 10 by a format converter 12. Then the converter 12 carries out the format 10 and the conversion data 11 based on a conversion program and an instruction, and outputs the result of conversion to an output device 5. The conversion program contained in the converter 12 includes such basic instructions for decision of conditions, the branching, the repetition, the call of a subroutine, etc., in addition to the conversion of formats. Thus the execution or non-execution of the format 10 can be selected and also the repetition of the same format can be carried out. As a result, about 25 lines (one screen), for example, can be printed with a single operation. Then the change of an application program is not required.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a format conversion device, and particularly to a format conversion device for data output to character display devices such as computer peripherals such as CRT terminals and printers. .

[Prior Art] FIG. 3 is a block diagram showing a conventional format conversion device. In the figure, (1) is an application program that performs certain processing, (2) is a conversion format that determines the arrangement of conversion stops, and (3) is a block diagram showing a conventional format conversion device. ) is the conversion data stored as a digital signal, (4) is the conversion format (2)
, a format converter that performs format conversion based on the converted data (3), and (5) an output device to which the format-converted data is supplied.

Next, the operation will be explained. When displaying using the output device (5), it is common to divide the display into fixed parts such as heading parts and space parts, and other variable parts. FIG. 4 shows an example of the display, in which (6) is a fixed part for setting headings and spaces, and (7) is a variable part such as the date.

These fixed parts and variable parts are registered in advance in the conversion format (2), and the conversion data (3) is added to these fixed parts and variable parts.
) and input it to the format converter (4), the fourth
An output result as shown in the figure can be obtained by the output device (5).

[Problems to be Solved by the Invention] Since the conventional format conversion device was configured as described above, one block is short, about 1 line or 2 to 3 lines, and multiple blocks (for example, one screen) are used. If you want to display the conversion format (2) and conversion data (3)
It is necessary to switch and use it repeatedly, and as a result,
In addition to the complexity of the application program structure,
There were problems such as the need to change the app application program in order to make corrections.

This invention was made to solve the above-mentioned problems, and its purpose is to obtain a format conversion device that can print, for example, about 25 lines (for one screen) in one operation. .

[Means for Solving Problem 1] A format conversion device according to the present invention is a format conversion device that outputs character data from a format converter based on a conversion format and conversion data, and a conversion program is built into the format converter. The system also controls character code conversion.

[Function] In the present invention, the conversion program built into the format converter incorporates basic instructions such as condition judgment, branching, repetition, and subroutine calls in addition to format conversion, and executes the conversion format. , you can select not to execute it, and you can also execute (repetition of the same format).

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is a block diagram of one embodiment of this invention, (1),
(5) is the same as described above.

In FIG. 1, (11) is provided separately from the application program (1)! A conversion format with a built-in L conversion command, (12) is conversion data consisting of conversion target data corresponding to the conversion format (11) and data that controls the conversion format (11), and (12) has a conversion program built-in. This is a format converter that executes conversion format (11) and conversion data (12) based on a conversion program and outputs character data.

Next, the operation will be explained. Conversion format/to (10
) is registered with a format for one screen, the conversion command in the conversion format (10) is read out by the format converter (12), and the format converter (
12) executes the conversion format (10) and conversion data (11) as instructed according to the conversion program, and outputs the conversion result to the output device (5). FIG. 2 shows the relationship between the conversion data (U) and the conversion format (lO) resulting from this execution.

Although the above embodiment has been explained using an example of an output device of a computer peripheral device, it goes without saying that the present invention can also be applied to a general-purpose character communication device.

[Effects of the Invention] As described above, according to the present invention, in a format conversion device that outputs character data from a format converter based on a conversion format and conversion data, a conversion program is built in the format conversion device. ,
Since character code conversion is controlled, a large amount of conversion can be executed in one operation, and the structure of the re-application program can be simplified by creating a conversion format separately from the application program. At the same time, it is possible to produce application programs in parallel, and by changing only the conversion format, output results with different images can be obtained, which has the effect of making it possible to create application programs with good maintainability.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing an embodiment of a format conversion device according to the present invention, FIG. 2 is an explanatory diagram showing the relationship between the conversion format and conversion data according to the invention, and FIG. 3 shows a conventional format conversion device. The block diagram in FIG. 4 is an explanatory diagram showing an example of display in a conventional format. In the figure, (10) is a conversion format, (11) is conversion data, and (12) is a format converter. Note that the same reference numerals in each figure indicate the same or equivalent parts.
