Abstract

Conversion of a double-byte representation of a character in a first interchange code to a double-byte representation of the character in a second interchange code is taught. The double-byte representation is used to provide column and row indices into a conversion array. This occurs through comparison of the first and second bytes of the representation to first and second national language verification arrays, respectively. The first byte is compared against the first national language verification array to return a first value. The second byte is compared against the second national language verification array to return a second value. The first and second values are then evaluated against first and second range limits, respectively, which, if met, validate the returned values as indices into a national double-byte translation table.
