MIGRATION SUPPORT SYSTEM

摘要

PROBLEM TO BE SOLVED: To facilitate a conversion of a program targeted for migration in the migration accompanied by a switch to a different character code system.SOLUTION: A working PC1 (migration support device) comprises: a character code conversion unit 11 that converts a character code from an EBCDIK+KEIS code to a UTF-8 code; a program conversion unit 12 that converts an input program 22 into an output program 32; an exchange information generation unit 13 that causes the output program 32 to read character data having the UTF-8 code allocated, and thereby generates exchange information determining the number of areas on a memory specified by the output program 32 as same as the number of bytes of a byte string expressing the EBCDIK+KEIS code allocated to the character data as to the read character data; and an area storage unit 14 that stores one UTF-8 code allocated to the read character data in areas composed of the number of areas determined by the exchange information E.SELECTED DRAWING: Figure 1
