Abstract

PURPOSE:To simplify a program without being conscious of printer environment. CONSTITUTION:A JCL is stored in a JCL storage device 2. When an OS in an OS part 10a is started by a user program, a JCL input part 11 inputs the JCL from the device 2 and transfers the JCL to a file definition sentence judging part 12. The judging part 12 refers to the JCL inputted by the input part 11 and judges the existence of 'KANJI' (Chinese character) printer file definition sentence. When the definition sentence exists, a code conversion part 13 converts an output record 4a from an one-byte code into a two-byte code while referring to a conversion table 20 and transfers the converted result to an output part 14. However, when no definition sentence exists, the output record is transferred to the output part 14 as it is without executing code conversion and the output part 14 outputs the received code 4a to a 'KANJI' printer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer control system for an information processing device.

[0002]

2. Description of the Related Art In the conventional printer control system, when a 2-byte code is input and output to a Kanji printer for printing, an output record must be created in 2-byte code.

Next, a conventional example will be described with reference to the drawings.

FIG. 4 is a block diagram showing a configuration in the case of printing a conventional ANK character, and FIG. 5 is a block diagram showing a configuration in the case of printing a conventional example of Kanji characters.

The printer control system shown in FIG. 4 includes a CPU 1b for information processing and a Kanji printer 3 for printing ANK characters with a 1-byte code and printing Kanji with a 2-byte code. The CPU 1b is configured to include an OS unit 10b in which an operating system (hereinafter referred to as OS) operates and a user program unit 30b in which a user program operates. When outputting ANK, the user program unit 30b operates the 1-byte code output program 31a to operate the Kanji printer 3
The output record 4a was output to.

The control system of the printer shown in FIG. 5 has the same configuration as that of FIG. 4, but the user program section 30b of the CPU 1b.
When outputting a kanji, the program 31b for outputting a 2-byte code was operated to output the output record 4b to the kanji printer 3.

According to this method, when outputting both a 1-byte code and a 2-byte code, two types of byte codes are output, a 1-byte code output program 31a and a 2-byte code output program 31b. To do 2
One program was needed.

[0008]

In the conventional printer control method described above, the 1-byte code output program 31a and the 2-byte code output program 31b are separately created from the beginning depending on the conditions such as the environment. In order to output the 1-byte code output program 31a to the Kanji printer 3, the 2-byte code output program 31b has to be modified or newly created, which is troublesome, time-consuming, and expensive.

[0009]

A printer control system according to the present invention comprises a JCL storing means for storing a JCL file definition statement for designating an operating system, and a conversion table in which a 1-byte code and a 2-byte code are associated with each other. And a JC for sequentially inputting JCL from the JCL storage device
1 from an L input means, a file definition statement determination means for determining the presence or absence of a Kanji printer file definition statement from the JCL input by the JCL input means, and a user program input from the determination result of the file definition statement determination means. It has a code conversion means for converting an output record, which is a byte code, into a 2-byte code by referring to the conversion table, and an output means for outputting the code converted by the code conversion means to a Kanji printer.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, FIG. 2 is an explanatory diagram of the conversion table shown in FIG. 1, and FIG.
2 is a flowchart showing the operation of the OS unit shown in FIG. 1.

In the printer control system shown in FIG. 1, a CPU 1a for information processing, a JCL storage device 2 such as a magnetic disk device for storing a JCL file definition statement for designating an OS, and an ANK character as a 1-byte code. It is composed of a kanji printer 3 which can print and print kanji with a 2-byte code.

The CPU 1a includes a conversion table 20 that associates 1-byte codes with 2-byte codes, an OS section 10a on which an OS operates, and a user who operates a 1-byte code output program 31a, which is a user program. It is composed of a program section 30a. The user program section 30a has a program 31 for outputting a 1-byte code.
The output record 4a from a is output to the OS unit 10a.
The OS unit 10a includes a JCL input unit 11 that sequentially inputs JCL from the JCL storage device 2, a file definition statement determination unit 12 that determines whether or not there is a Kanji printer file definition statement from the JCL input by the JCL input unit 11, and a file. A code conversion unit 13 that converts the output record 4a input from the determination result of the definition statement determination unit 12 into a 2-byte code using the conversion table 20, and an output unit that outputs the code converted by the code conversion unit 13 to the Kanji printer 3. It is composed of 14 and.

The conversion table 20 includes a 1-byte code storage unit 21 for storing a 1-byte code and a 2 corresponding thereto.
A 2-byte code storage unit 22 for storing a bytecode,
1-byte code storage unit 21 and 2-byte code storage unit 22
And one entry 23.

Next, the operation of the printer control system of the present invention thus constructed will be described. First, the JCL is stored in the JCL storage device 2. From the user program,
When the OS of the OS unit 10a is started, in step 31, the JCL input unit 11 causes the JCL storage device 2 to delete the JCL.
Is input and passed to the file definition statement determination unit 12. In step 32, the file definition statement determination unit 12 refers to the JCL input by the JCL input unit 11 and determines whether or not there is a Kanji printer file definition. If there is a Kanji printer file definition statement in step 32, the code conversion unit 13 refers to the conversion table 20 in step 33, converts the output record 4a from a 1-byte code to a 2-byte code, and outputs it to the output unit 14. Pass to. If there is no Kanji printer file definition statement in step 32, code conversion is not performed and the output record 4a is passed to the output unit 14 as it is. In step 34, the output unit 1
4 is output to the kanji printer 3.

[0016]

According to the printer control method of the present invention, by adding a conversion table for converting a 1-byte code into a 2-byte code, it is possible to make the program simple because it is not necessary to be aware of the printer environment. There is.
