ABSTRACT:
In a computer system provided with a plurality of computers handling different types of character code sets, a multiple character code set input/output conversion system according to the present invention converts character code strings based on a character code set used in a text file into internal character code strings based on the internal character code set commonly used by the plurality of computers and in turn converts the internal character code strings into character code strings based on a specific character code set. The code conversion means to convert input character code strings to internal character code strings based on the internal character code string and internal character code strings to other character code strings comprises a plurality of code conversion programs which convert character code strings into internal character code strings and internal character code strings to character code strings, a plurality of conversion tables with arrays of addresses for invoking code conversion programs and table registers where pointers to applicable conversion tables are set.
