Multiple character code set input/output conversion system
First Claim
1. A multiple character code set input/output conversion system for a computer system provided with a plurality of computers handling different kinds of character code sets comprising:
- an input character code conversion means for converting character code strings based on a character code set used in a text file into internal character code strings based on an internal character code set commonly used by said plurality of computers, andan output character code conversion means for converting said internal character code strings to other character code strings based on a specific character code set.

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.

9. A multiple character code set input/output conversion system for computer systems handling a plurality of mutually distinct character code sets, comprising:
-
means for establishing a common code set common in said computer systems; means for inputting a first text data described in a first character code set; means for receiving input first text data and converting said first text data into a common text data described by said common code set; means for converting said common text data into a second text data described by a second character code set distinct from said first character code set; and means for outputting said second text data.
