If the DBCS field is surrounded by shift-in and shift-out characters, then use
GRAPHIC EXTERNAL. This is identical to
GRAPHIC, except that the first and last characters (the shift-in and shift-out) are not loaded.
The syntax for the
EXTERNAL data type is:
GRAPHIC indicates that the data is double-byte characters.
EXTERNAL indicates that the first and last characters are ignored. The
graphic_char_length value specifies the length in DBCS (see "GRAPHIC").
For example, let [ ] represent shift-in and shift-out characters, and let # represent any double-byte character.
To describe ####, use
POSITION(1:4) GRAPHIC or
To describe [####], use
POSITION(1:6) GRAPHIC EXTERNAL or
POSITION(1) GRAPHIC EXTERNAL(2).
