ASCII JIS Kanji double-byte characters are being converted to EBCDIC. ASCII JIS Kanji double-byte characters are enclosed within the shift-out escape sequence ESC $ @ or ESC $ B, and the shift-in escape sequence ESC ( B or ESC ( J. The character after the $, with the specified ordinal value, is not valid for a JIS Kanji shift-out sequence. For translation modes containing both single-byte and double-byte data, the erroneous escape sequence will be converted using single byte ASCII to EBCDIC conversion tables. Data will continue to be converted in this manner until a valid Shift-out escape sequence is encountered.

For translation modes that convert pure double-byte data only, the erroneous character and the escape character will be inserted without conversion and the conversion routine will move to the next character assuming it to be a valid first double-byte character.
