This code scheme applies to the AS/400 system, System/36, System/38, as well as
the System/370 system. A different DBCS code scheme, called the IBM Personal
Computer DBCS code scheme, is used on the Personal System/55. For details of
the IBM Personal Computer DBCS code scheme, refer to IBM PS/55 publications.
Shift-control double-byte characters
When the IBM-host code scheme is used, the system uses shift-control characters to
identify the beginning and end of a string of double-byte characters. The shift-out
(SO) character, hex 0E, indicates the beginning of a double-byte character string.
The shift-in (SI) character, hex 0F, indicates the end of a double-byte character
string.

Each shift-control character occupies the same amount of space as one
alphanumeric character. By contrast, double-byte characters occupy the same
amount of space as two alphanumeric characters.
When double-byte characters are stored in a graphic field or a variable of graphic
data type, there is no need to use shift control characters to surround the
double-byte characters.
