Description

  The present invention relates to a technique that can handle external characters uniformly in a distributed system of information processing apparatuses without contradiction.

  When information processing systems are decentralized, for example, when it becomes necessary to distribute data between systems in remote locations, it is necessary to unify the handling of character code systems, especially external characters, which differ depending on the hardware. Has become a problem.

  Specifically, if you want to handle data uniformly between different platforms, for example, mainframes connected via communication lines, workstations, and personal computers, the hardware manufacturer between each platform, Or, even within the same manufacturer, the character code system, particularly the character code system other than the standard characters called external characters, differs depending on the model.

  Under these circumstances, when handling characters that are not supported by the standard JIS, a character font must be created for each platform individually using a font editor or the like. They had to rely exclusively on the operator's manual work.

In this regard, in JP-A 3-2467 6 1 JP, matched by comparing the external character that is used in the copy source document file provided with external character management table in the external storage medium, and a nonstandard character existing in the copy destination stores the external character you external character management table, along with copied to the copy destination external character storage means a copy source of the external character if matching external character does not exist, the private character character code and the previous SL in external character storage means It is to be stored before Symbol external character management table in association with the storage position.

  However, since the conventional technology presupposes external character management on the same platform (in the conventional technology, a single type of word processor is assumed), systems having different code systems, such as mainframes and UNIX, are used. The code areas that can be defined by users differ between workstations, and it was impossible to convert external characters when the corresponding code itself did not exist.

  In addition, in the prior art, since the character codes for external characters are managed for each document, extra information is added for each document (for each data), and data distribution based on communication is assumed. When considered, the amount of data increased, which was not realistic.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a system that can handle external characters uniformly between platforms connected by a network.

As shown in FIG. 1, which is a principle diagram, the present invention includes a first character string storage means (1) and a second character string storage means (2) based on a character code system. In a distributed information processing system capable of transmitting character strings as information by connecting them via a communication line (3), a character string output from the first character string storage means (1) is stored in the second character string. The character code management device is provided with code conversion means (4) for converting into character codes based on the character code system in means (2).

  As a second means, the code conversion means (4) converts a character code in the first character string storage means (1) into a character code in the second character string storage means (2). Was provided.

  As a third means, the code conversion means (4) takes out the character pattern from the first character string storage means (1), and uses this character pattern in the corresponding second character string storage means (2). It was assumed that a character pattern processing unit that applied to the character code and output to the communication line (3) was provided.

  As a fourth means, the code conversion means (4) converts the conversion information registered in the code conversion table belonging to the first character string storage means (1) into the second character string storage means (2 The code conversion table belonging to) has a function of transmitting via the communication line (3).

  In the first means, by providing the code conversion means (4), when the first character string storage means (1) outputs to the communication line (3), the second character string storage means ( Since the character code to be registered in 2) is specified, the character code defined by the external character in the first character string storage means (1) is also surely registered in the second character string storage means (2). be able to. For this reason, external characters can be handled uniformly in the distributed processing system connected by the communication line (3).

  According to the second means, by providing a code conversion table as the code conversion means (4), an external character to be registered from the first character string storage means (1) to the second character string storage means (2). The code conversion is extremely easy.

  According to the third means, the character pattern itself is circulated using the communication line (3) using the pattern processing unit, so that, for example, the character pattern created by the first character string storage means (1) is directly used. The second character string storage means (2) can be used, and it is not necessary to regenerate the character pattern for each platform (each character string storage means), and the character pattern can be efficiently managed.

  According to the fourth means, by distributing the information of the code conversion table itself via the communication line (3), it is extremely easy to update the conversion definition between platforms, and unified management of external characters between platforms is more completely performed. be able to.

  According to the present invention, it is possible to handle external characters uniformly between different platforms connected by a network.

Embodiments of the present invention will be described below with reference to the drawings.
[Description of system configuration]
FIG. 2 shows the system configuration of this embodiment. This embodiment is an example of distributed processing in a network such as a financial institution. The head office has an information processing system 5a by a mainframe, an information processing system 5b by a workstation at a regional center branch, and a personal computer at a branch. The information processing system 5c has a different platform.

  In each information processing system, for example, databases 6a, 6b, 6c such as customer lists are constructed. In these databases, the character code systems are different, and the code addresses of the user areas are also different. For example, a JEF code is used for the main frame (6a), an EUC code is used for the workstation (6b), and a shift JIS code is used for the personal computer (6c). Therefore, each external character area code is also different.

  Each of the databases 6a, 6b, and 6c has font files 7a, 7b, and 7c, and character patterns defined in the character codes registered in the external character area are read from the font files 7a, 7b, and 7c. It is displayed on each display device 8a, 8b, 8c.

Each information processing system 5a, 5b, 5c has character code management devices 4a, 4b, 4c. The configuration of this character code management device will be described below.
[Description of Character Code Management Device] FIG. 3 shows the configuration of the character code management device in more detail.

  In the figure, for convenience of explanation, a configuration for distributing external character information from the information processing system 5a constituting the main frame of the head office to the information processing system 5b constituting the workstation of the regional center branch is shown.

  In the figure, the character code management devices 4a and 4b are composed of conversion processing units 10a and 10b, code conversion tables 11a and 11b, and delivery data 12a and 12b. The code conversion tables 11a and 11b and the delivery data 12a and 12b are specifically registered in the RAM or the storage device in a file format.

  The code conversion tables 11a and 11b are tabulated conversion definitions for external characters, for example, which character code of the information processing system 5b on the reception side corresponds to the external character defined in the information processing system 5a on the transmission side. Is specified.

  Here, the functions of the transmission side conversion processing unit 10a and the reception side conversion processing unit 10b are different. That is, the transmission side conversion processing unit 10a reads a character pattern from the font file 7a, converts the character code on the reception side corresponding to the character code to which the character pattern is assigned based on the code conversion table 11a, Is transmitted to the receiving side character code management device 4b through the communication line 3 as delivery data.

On the other hand, when the receiving side character code management device 4b receives the delivery data 12b from the transmitting side character code management device 4a, the receiving side character code management device 4b performs an operation of registering it in its own code conversion table 11b. Through these operations, the code conversion tables 11a and 11b are uniformly updated, and unified management at the time of distribution of external characters is realized.
[Processing flow of sending side conversion processing unit]
FIG. 4 illustrates the processing of the transmission side conversion processing unit 10a in more detail.

  First, the transmission side conversion processing unit 10a checks the validity of the input information such as whether there is a user input error or whether the parameter is correct (step 401).

  Subsequently, the font file 7a is opened and expanded on the memory of the conversion processing unit 10a (402). Next, the code conversion table 11a is read into the conversion processing unit 10a (403).

  Subsequently, the number of character patterns held in the font file 7a is read by the conversion processing unit 10a, and the number is set in its own counter as the number of loops (404).

  Next, external character pattern data is read from the font file 7a (405). Then, the correspondence between the distribution source code system (here JEF code system) of the external character to be distributed (output to the communication line 3) and the distribution destination code system (here EUC code system) is set (406). For example, a user external character registration code address in the JEF code system and a user external character registration code address in the EUC code system are given in advance as the correspondence relationship. It is possible to calculate to which code address of the distribution destination the external character read from 7a is applied. Then, the correspondence obtained in the step 406 is written into the code conversion table 11a developed on the memory (407).

  After repeating the above steps 404 to 407 for the designated external character code, the transmission side conversion processing unit 10a sends the character pattern data obtained through the above processing and the correspondence relationship of the external character code to the delivery data 12a. As a file (408).

Then, the code conversion table 11a updated based on the above is written on the storage device (409), and then the font file 410 is closed (410).
[Structure of delivery data]
FIG. 5 shows the format of the delivery data 12a.

  The delivery data 12 a is composed of a header part 15, a list part 16, and a character data part 17. The “OK flag” located at the head of the header portion 15 indicates the normal end of the character data export, and “0” is registered as the normal end value. In the case of abnormal termination, a value other than 0 is registered.

  “0” is registered as the standard mode in the “code conversion definition execution mode”, and “1” is registered when the update is indicated, and “2” is registered when the update is indicated. In the “original code system length” and “destination code system length”, the code system lengths (7 or 8 bits) of the distribution source and distribution destination are registered, respectively.

  Code names set in advance for each platform are registered in the “distribution source code system” and the “distribution destination code system”. Here, for example, when the distribution source is a mainframe as in the present embodiment and has an EBCDIC code system based on the JEF code and ASCII code, the code name “JefAscii” is designated. When the distribution destination is a workstation that employs the EUC code, the code name “EUC” is designated. The “distribution destination code system” registers a NULL code in the standard mode or the transfer update mode.

  In the “character horizontal size”, “character vertical size”, “letter horizontal size”, “letter vertical size”, and “character data size”, information on the size of characters to be distributed is registered. This is to reflect the character size at the distribution source also at the distribution destination.

  The “number of characters to be exported” designates the number of characters stored as a file in the delivery data. In addition, the length of the code list to be transmitted is registered in the “export code list length”.

In the list part 16, "distribution source character code" and "distribution destination character code" are registered in pairs for the necessary characters. Here, a character code based on the “distribution source character code system” registered in the header section 15 is registered as the “distribution source character code”, and the “distribution destination character code” is registered in the header section 15. Character codes based on “distribution character code system” are registered. As the “distribution destination character code”, a NULL code is registered in the standard mode or the transfer update mode.

  Here, the list part 16 is created including a character code having no character (external character). Therefore, the “export code list length” in the header section 15 described above does not match the number of characters (number of external characters) actually transmitted.

In the character data portion 17, “distribution source character code” and “character pattern data” (font) are registered in pairs.
[Processing flow of receiving side conversion processor]
FIG. 6 shows a processing flow in the receiving side conversion processing unit 10b.

  The receiving side character code management device 4b first checks the validity of the delivery data 12b received via the communication line 3 (601), and then reads the delivery data 12b into the conversion processing unit 10b (602).

  Next, the user's own font file 7b is read and expanded on the memory (603). Next, the code conversion table 11b is read and is also expanded on the memory (604).

  Subsequently, the conversion processing unit 10b sets this as the number of loops in its own counter based on the number of external characters obtained from the delivery data 12b (605). Next, when the information regarding the character size obtained from the delivery file 12b is different from the stored size of the font file 7b owned by the delivery file 12b, enlargement or reduction processing is performed (606). Further, if the data format of the character pattern (font) is different, the format is converted so as to conform to its own format (607).

  After completing the above processing, the received external character is stored in its own font file 7b developed on the memory. Subsequently, the code correspondence relationship between the distribution source code system and the distribution destination code system obtained from the delivery data 12b is written in its own code conversion table 11b developed on the memory (609).

  After the processes in steps 605 to 609 are repeated for the number of characters set in the counter, the code conversion table 610 expanded in the memory is written back to the storage device (610), and the updated font file 7b is closed ( 611).

  In the above description, the information processing system 5a of the mainframe is the transmission side and the information processing system 5b of the workstation is the reception side, but any information processing system 5a, 5b, 5c may be the transmission side and the reception side. That is, the contents of the personal name database 6c including newly created external characters input at the branch (information system 5c) are reflected on the regional center branch (information system 5b) and the head office (information system 5a) through the communication line 3 to reflect them. It is also possible to display on the display devices 8b and 8c.

  Thus, the distribution of the external character code converted through the communication line 3 is realized, and the character pattern (font) itself can be distributed, so that it is not necessary to recreate the external character for each platform. A database of names including external characters can be managed in a unified manner between platforms with different code systems.

Also, the conversion processing units 10a and 7b periodically repeat the flow shown in FIG. 4 and FIG. 6 so that when an external character is updated on any platform, this is quickly reflected on the other platform. Can do.
[Process for distributing the conversion table itself]
In the above explanation, the distribution between platforms including character patterns (font data) has been described when distributing external character information, but only the contents of the code conversion table 11a are performed without distributing character patterns and additional information on characters. It may be distributed through the communication line 3.

  FIG. 7 shows an outline of processing when only the code conversion table 11a is distributed between platforms. For convenience of description, the schematic configuration will be described with reference to FIG. Therefore, in FIG. 7, system A shows processing in the transmission side character code management device 4a in FIG. 3, and system B shows processing in the reception side character code management device 4b in FIG.

  First, the transmission side conversion processing unit 10a of the transmission side character code management device 4a determines whether or not the character to be converted is a rule conversion, for example, a character within the range of JIS. As a result, in the case of a character defined in JIS, rule conversion is possible, so that the character code corresponding to the partner system is converted and transmitted by the rule conversion program owned by itself.

  If it is not subject to rule conversion, for example, if it is an external character or a manufacturer-specific character, it is determined whether or not it exists in the memory transfer conversion table. Here, the memory transfer conversion table refers to the case where the conversion rule is transmitted to the receiving system together with the data to be distributed, and the rule is expanded in the memory in the receiving system.

  If the character does not exist in the memory transfer conversion table, it is determined whether or not the character exists in the external code conversion table 11a. Here, when performing conversion using the external code conversion table 11a, the transmission-side conversion processing unit 10a converts the character code based on the code conversion table 11a and transmits the character code to the reception-side system.

  On the other hand, if the character does not exist in the external code conversion table 11b, the default conversion of the irregular conversion character is performed. This is a process of setting a code to which a code meaning a character that cannot be converted in advance is assigned.

  The reception-side character code management device 4b performs the same processing as the transmission-side character code management device 4a. Here, when the external code conversion table 11b is inconsistent with the external code conversion table 11a on the transmission side, there is a possibility that default conversion of irregular conversion characters may be performed depending on the character code. Therefore, in this embodiment, the code conversion table 11a itself is transmitted as the delivery data 12a to the receiving side character code management device 4b through the communication line.

  FIG. 8 shows a format when the contents of the code conversion table 11a are transmitted as delivery data 12a. This file is composed of a header portion 20 and a data portion 21. The header portion 20 includes “file identification name”, “header length”, “number of character code correspondences”, “reserved area” (128 bytes), “ Corresponding character code system number "and" character code system information tables (1) to (20) ".

  In the data portion 21, a character code correspondence table between character code systems is registered. In the receiving side character code management device 4b that has received this file as the delivery data 12b, the receiving side conversion processing unit 10b reads it and updates its own code conversion table 11b.

In the above description, an example in which a character pattern (font), character information associated therewith, and a code conversion table are distributed between the character code management devices 4a, 4b, and 4c via the communication line 3 has been described. As shown in Fig. 5, only font files 7a, 7b, 7c
Alternatively, it may be distributed on a physical storage medium such as a floppy disk.
