Description

Description: TECHNICAL FIELD The present invention relates to an output control system capable of simultaneously displaying or printing multilingual character data in an information processing device.

[Conventional technology]

The JEF system is one of the systems for processing Japanese information including kanji and kana characters. This JEF system uses a 2-byte code and incorporates 3418 characters consisting of JIS first-level kanji and non-kanji as basic characters on the hardware so that they can be used at all times.
Further, 10819 characters including extended kanji, JIS second level kanji, and user-defined characters can be used as additional characters when necessary.

Similarly, there are a Korean information processing system and a Chinese information processing system as information systems used mainly for Kanji. For example, one KEF system of the Korean information processing system uses the same 2-byte code as the JEF system.
It incorporates 3403 basic characters consisting of first-level kanji and non-kanji, and makes 10249 additional characters available when needed. Also, one of the Chinese information processing system
The two CEF systems also use 2-byte codes,
Class Kanji 3755 characters, National Non-Kanji 682 characters, National Mark No. 2
It has built-in basic characters consisting of 3008 Kanji, and 3394 additional characters can be used when needed.

FIG. 2 shows an example of a conventional character pattern generating mechanism in a line printer, 21 is a line printer,
22 is a character pattern generator CG having a RAM, 23 is a basic character floppy with built-in hardware, 24 is a second floppy with built-in hardware, 25 is an additional character pattern set file on an external storage device, and 26 is an external storage device. It is the above character pattern master file.

This line printer is a Japanese line printer NL for each JEF, KEF, and CEF system.
P, Korean line printer KLP, Chinese line printer CLP are commonly used. In either case, the basic character floppy 23 stores the basic character pattern, and the second floppy 24 stores a part of the patterns of the additional character as an option (however, CLP).
Then, two basic characters floppy are used). The character patterns of the basic floppy 23 and the second floppy 24 are automatically loaded into the RAM of the character pattern generator CG22 when the line printer is turned on (called initial loading). Further, the additional character pattern in the additional character pattern set file 25 is loaded at the start of the job execution (called preload) only when the JCL definition that defines the execution content of the user job is instructed. On the other hand, the character pattern master file 26 stores the basic character patterns and additional character patterns of the system, and the characters that have not been loaded in the character pattern generation unit CG22 are dynamically loaded at the time of character output. (Called dynamic loading).

These JEF, KEF, and CEF systems have almost the same scale, and are common in that basic characters are standardly equipped on the hardware, and missing characters are supplemented by additional character patterns. ， Each has its own operating system.

Even though Japanese, Korean, and Chinese use the same Kanji characters, each one contains a unique Kanji character, so it must be managed as an independent system to avoid confusion. Because there was. As a result, these national language processing systems had to be treated as completely separate systems using the same 2-byte character code.

[Problems to be Solved by the Invention] As described above, conventionally, each information of Japanese, Korean, and Chinese of the kanji system is processed independently, and further, it is printed by using a dedicated printer or display device. It was displayed and output. Therefore, it is not possible to output a mixed message of national languages on the same screen, such as output of a message in each national language, or output in a national language sentence contrast format in the information translation process.

In order to enable this, it is necessary to have character patterns of multiple languages, identify the type of language of the code system, and convert them to the corresponding character patterns. However, it is necessary to store the character patterns for each language. There is a problem that a storage area becomes necessary and the storage space becomes large.

[Means for solving problems]

According to the present invention, in order to enable simultaneous output of characters of multiple Kanji characters including Japanese, the necessary character patterns are kept to a minimum storage space. Each language is not stored at the same time, only the basic character of one national language such as Japanese is built into the hardware, and the characters of other national languages are handled in the same way as the option characters or additional characters in the Japanese system. The initial pattern, preload, and dynamic load are used to reflect in the character pattern generation part.

According to the configuration of the present invention, in the information processing apparatus having the character pattern generating means and capable of printing or displaying the character data of two or more national languages, the character pattern generating means is one of the two or more national languages. Preselected 1
In case of printing or displaying and outputting only the character data of one selected national language, which has a first area for storing basic character patterns of two national languages and a second area for storing auxiliary character patterns In the second area, an additional character pattern for the preselected basic character pattern of one national language is stored, and when the character data of two or more national languages are simultaneously printed or displayed and output, The second area is characterized in that the character patterns of one of the above-selected one national language are stored, and the character pattern according to the national language can be selected.

〔Example〕

 The details of the present invention will be described below with reference to examples.

The following conditions must be met in order to allow different character codes and character pattern systems in different languages to coexist using the same 2-byte code.

(1) In order to allow the hardware side to recognize the same 2-byte code as different characters, a memory area for storing data is provided for each language, and a dedicated memory area is provided.

(2) A shift code is provided to identify the type of national language when outputting characters.

(3) A function is provided to identify the loading location when loading character patterns.

a represents a JEF identification ID, 20 represents a KEF / CEF additional character pattern set, and 20a represents a KEF / CEF identification ID.

The host 1 is a Japanese line printer NLP (hereinafter simply N
2) Print command and JEF or KE
Supply character data of F and CEF codes. JEF, K
Each code of EF and CEF is composed of 2 bytes. Furthermore, regarding printout data, JEF, KE
A shift code is used to identify the type of F or CEF. This shift code is inserted at the boundary position where the code system is switched or at each code.

In the NLP 2, the print processing unit 3 identifies the print command from the host 1, and the character pattern generating unit 4 converts the character data into the character pattern and executes the printing. The print processing unit 3 simultaneously identifies the code system type of the character data based on the shift code, and selects the corresponding table from the JEF code conversion table 4a or the KEF / CEF code conversion table 4b. The character pattern generation unit 4 uses the selected code conversion table (4a or 4b) to convert the code of the input character data into the address of the character pattern memory 5 and read the character pattern from the corresponding address.

The character pattern memory 5 uses the initial loading of this character pattern set at power-on, the preloading of auxiliary character patterns at the start of job execution, and the dynamic loading of additional character patterns at the time of character output. The pattern is registered. Therefore, the character pattern memory 5 has 4 Kbytes of JEF basic character areas 6 and 10.
It is divided into K-byte auxiliary character areas 7.

The contents of the JEF basic character floppy 8, that is, the JEF basic character pattern set is initially loaded in the JEF basic character area 6 when the power is turned on. Similarly, the auxiliary character area 7 is initially loaded with the contents of the auxiliary floppy 9 for JEF or KEF / CEF depending on whether the output is single Japanese information or multilingual information.

That is, in the case of single Japanese information output, the JEF auxiliary character pattern set is initially loaded using the JEF auxiliary floppy, and in the case of multi-language information output, KEF / CEF additional character floppy is used. A set of character patterns and CEF character patterns are initially loaded as supplementary characters to the base character.

The JEF auxiliary floppy and the KEF / CEF auxiliary floppy are identified by the file name, and the storage area at the time of initial loading is determined.

In this way, the NLP 2 is initialized with the character pattern generation function depending on whether Japanese information is output or multilingual information is output.

Next, in order to make up for the lack of the initialized character patterns,
At the start of execution of a user job, the additional character pattern set specified by the user is added to the additional character pattern file 18 according to the contents defined by the user in JCL (job control language).
Preloaded from.

The additional character pattern file 18 includes a JEF additional character pattern set 19 and an additional character pattern set 20 for KEF / CEF. These are the job management unit 1
Under the control of 0 and the data management unit 11, it is selected by referring to the JEF identification ID 19a and the KEF / CEF identification ID 20b and transferred to the NLP 2.

The print processing unit 3 of the NLP 2 stores the transferred additional character pattern set in a predetermined position of the auxiliary character area 7 of the character pattern memory 5 according to each ID. At this time, the JEF code conversion table 4a and the KEF
The code / address conversion pair data is registered in the corresponding one of the / CEF code conversion tables 4b.

The JEF character pattern master file 13 holds JIS first level, JIS second level, extended Kanji and character pattern sets of user-defined characters, and the KEF character pattern master file 14 has KEF first level, KEF second level, Holds extended Kanji and user defined character pattern sets, and the CEF character pattern master file 15 is the first national standard.
It has character patterns of character class, national standard 2nd class, extended kanji, and user-defined characters.

The JEF character set management information file 16 holds a code table of usable characters in the JEF code system. Similarly, the KEF / CEF character set management information file 17 holds a code table of usable characters in the KEF and CEF code systems.

The character set management unit 12 manages the files 13 to 17 and functions when creating a pattern set of supplementary characters or additional characters. When the data management unit 11 detects a character that NLP2 does not have when outputting the character,
The corresponding character pattern is extracted from the master files 13 to 15 and dynamically loaded.

〔The invention's effect〕

As described above, according to the present invention, by handling character patterns of other national languages as supplementary character patterns for basic character patterns of one national language, character data in which multiple languages are mixed can be efficiently used with a small character pattern memory capacity. In addition, it is possible to print or display at low cost, and it is possible to expand the range of information processing as compared with the conventional printer or display device dedicated to a single language.
