Problems solved by technology

However, the correction pattern differs depending on the byte column of the character stored in the area, so correction becomes a very cumbersome and difficult operation
In the prior art including the technology of Patent Document 1, there is no improvement scheme for this kind of work

Embodiment Construction

[0026] Such as figure 1 As shown, the work PC 1 is a computer operated by a worker in charge of migration from the current computer 2 to the new computer 3, and is the migration support device of the present embodiment. The work PC 1 acquires the input file 21 and the input program 22 from the current computer 2 , performs predetermined conversion (details will be described later), and outputs them to the new computer 3 as the output file 31 and the output program 32 .

[0027] The current computer 2 (first computer) is a general-purpose host computer.

[0028] The new computer 3 (second computer) is an open server computer.

[0029] The input file 21 (first document file) is a document file including character data, and is legacy software of the current computer 2 . The character data in the input file 21 will be processed according to the character code system of the current computer 2. The current character code system processed by the computer 2 is EBCDIK for the charac...

Abstract

This work PC 1 (migration support device) includes: a character code converting unit (11) that converts an EBCDIK+KEIS code into a UTF-8 code; a program converting unit (12) that converts an input program (22) into an output program (32); an exchange information generating unit (13) which causes the output program (32) to read character data to which the UTF-8 code is allocated, and which generates exchange information E that defines, regarding the read character data, the number of areas on a memory specified by the output program (32) so as to be the same as the number of bytes of a byte sequence expressing the EBCDIK+KEIS code allocated to the character data; and an area storing unit (14) that stores a UTF-8 code allocated to the read character data in the areas the number of which is defined by the exchange information E.

Description

technical field [0001] The present invention relates to the technology of so-called legacy system migration (hereinafter sometimes simply referred to as "migration"), and in particular to the migration technology accompanying character code system switching. Background technique [0002] In recent years, many companies, municipalities, etc. have desired migration services for migrating business systems (legacy systems) previously running on current computers to new computers. As a form of migration, for example, there is an open system running from a general-purpose host computer (or office computer) to an OS (Operating System: operating system) such as WINDOWS (registered trademark), UNIX (registered trademark), or LINUX (registered trademark). Form of server computer migration. In addition, techniques related to migration have been widely disclosed, for example, in Patent Document 1. [0003] However, there are cases where a predetermined character code system is used (f...
