Abstract

PURPOSE:To curtail the use of a memory, and to easily curtail, correct and modify the coding system by tabling a character deviced by each application program. CONSTITUTION:By a character code table access means 3, a retrieval of a character code table 2 is executed, based on a key requested by a user. In the case the entry corresponding to the key does not exist, it is returned as an error to the user. In the case it exists, from which position the user desires to return it is decided, and in the case a start position is omitted, '1' is adopted as a start position. Also, with regard to return length, as well, it is decided in the same way, and in the case it is omitted, character-string length on the character code table is adopted. Subsequently, a necessary length portion is returned to the user from the start position of the entry concerned.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a unified character management system, and particularly to a unified character management system used in an aggregation program of an information processing device.

[Conventional technology]

Conventionally, the method for editing characters in application nine programs has been to define heading characters and embedded characters in a constant area. In particular, for kanji and control characters, a method of defining them using hexadecimal codes was adopted.

[Problem to be solved by the invention]

In the conventional method described above, each character is defined in a constant area for each application program, so as the scale of the program increases or the number of programs developed increases, the constant area increases and corrections due to character changes become difficult. The problem is that it has a large impact.

An object of the present invention is to provide a unified character management method that can reduce character definitions in each allocation program, reduce memory usage, and facilitate reduction, modification, and modification of coding systems. It is in.

[Means to solve the problem]

The unified character management system of the present invention has a table that stores kanji, alphanumeric characters, and control codes and can be searched by key, and indexes the table to return necessary parts of entries containing the characters. have.

〔Example〕

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

FIG. 1 is a professional diagram of an embodiment of the present invention. This embodiment is composed of a task 1, a one-character code tail 2, and a character code table access means 3'. Task 1 includes process 10, which is a program in processing units, and process f!
! 111 exists, and one process is further composed of a plurality of modules.

FIG. 2 is a diagram showing an example of the contents of process 0. Process 10 includes a main control process 10a, a search process 1°b, and an editing process 1.
0c.

FIG. 3 is a diagram showing an example of the contents of the character code table.

The character code table includes keys 20 used when searching,
It is composed of a character string 21 indicating the length of the character string and a character string 22.

FIG. 4 is a flowchart of the processing performed by the character code table access means, and the operation of this embodiment will be described below with reference to FIGS. 1 to 4.

The character code table access means 3 searches the character code table based on the key requested by the user (
Step 531). If there is no entry corresponding to the key (step 532), an error is returned to the user (step 833). If it exists, please check 1.
step 532), and determine from which position the user wants to return the item.Step S34. ) If +start position is omitted, 1 is adopted as the start position (step 535).

Also, the return length is determined in the same manner at step 836.
), if omitted, the character string length on the character code table is used (step 537). Next, the required length from the start position of the entry is returned to the user (step S
38> and [Effects of the Invention] As explained above, the present invention makes it possible to reduce the number of character definitions in each application program by creating a table of characters defined in each application program, thereby saving memory space. It has the effect of reducing usage and making it easier to reduce, modify, and modify the coding system.
